Comprehensive and Detailed Explanation:

In postpartum hemorrhage with a firm uterine fundus and intact placenta, a common cause is trauma such as a vaginal or cervical tear. Uterine atony (A) typically presents with a boggy uterus. The absence of systemic instability or coagulopathy makes options D and E less likely.

Toronto Notes 2023 – Obstetrics, Postpartum Hemorrhage:

“Continued bleeding despite a firm fundus and intact placenta should raise suspicion for genital tract trauma, especially cervical or vaginal lacerations.”

MCCQE1 Objectives – Obstetrics > Postpartum Complications:

“Candidates must differentiate causes of postpartum hemorrhage and identify when bleeding is due to trauma vs uterine atony.”

====================================================

The levonorgestrel-releasing intrauterine system (LNG-IUS) is the first-line treatment for heavy menstrual bleeding, particularly in women with risk factors for endometrial hyperplasia and contraindications to systemic hormones (e.g., morbid obesity, diabetes, OSA).

Toronto Notes 2023 – Gynecology, “Abnormal Uterine Bleeding” Section:

“The LNG-IUS is highly effective in reducing menstrual bleeding and improving hemoglobin levels. It is particularly recommended in women with obesity, chronic anovulation, or contraindications to estrogen.”

MCCQE1 Objectives (Obstetrics and Gynecology > 82-1: Abnormal Uterine Bleeding):

“Candidates must consider the LNG-IUS as a preferred non-surgical treatment for chronic heavy menstrual bleeding when endometrial pathology has been excluded.”

Oral contraceptives (C) are not first-line in morbid obesity due to increased thromboembolic risk. Cyclic medroxyprogesterone (D) is less effective than LNG-IUS. Hysterectomy (A) is definitive but should follow failure of conservative therapy.

Fibroadenomas can grow slightly or fluctuate in size. A minimal increase (from 1.5 cm to 1.7 cm) over six months is clinically insignificant. No malignant features are reported, and the previous biopsy confirmed benign nature. Annual follow-up is appropriate.

Toronto Notes 2023 – Obstetrics and Gynecology, “Breast Disorders” Section:

“Fibroadenomas are benign breast masses that may slightly enlarge. Routine imaging follow-up at 6 to 12 months is appropriate for lesions with benign imaging and histology.”

MCCQE1 Objectives (Obstetrics and Gynecology > 82-3: Breast Mass):

“Candidates must distinguish between benign and suspicious masses and determine appropriate intervals for follow-up imaging.”

Repeat biopsy (A) or surgery (B) is unwarranted without suspicious change. MRI (C) is not needed in stable, benign lesions. Tamoxifen (D) is not used for fibroadenomas.

====================================================

Dog bites from animals of unknown rabies status, especially from endemic regions and in patients with uncertain immunization status, require immediate post-exposure prophylaxis (PEP) including both rabies immunoglobulin and vaccine. The decision is urgent given the fatal nature of rabies.

Toronto Notes 2023 – Infectious Diseases, “Rabies Exposure”:

“Rabies PEP is indicated for bites from animals with unknown vaccination status or those showing abnormal behavior, particularly in endemic regions. PEP includes both vaccine and immunoglobulin.”

MCCQE1 Objectives (Public Health > 64-1: Rabies and Animal Bites):

“Candidates must recognize indications for rabies post-exposure prophylaxis.”

Ciprofloxacin (C) is not the antibiotic of choice (amoxicillin-clavulanate is preferred). Hydrogen peroxide (E) can be cytotoxic. Debridement (B) and CK (D) are not immediate priorities here.

====================================================

Comprehensive and Detailed Explanation:

Travel to rural Cambodia poses a high risk of malaria, which can be life-threatening in pregnancy. Antimalarial prophylaxis is strongly recommended for pregnant women traveling to endemic regions. Chloroquine or mefloquine (depending on resistance patterns) may be used in pregnancy under specialist guidance.

Toronto Notes 2023 – Infectious Disease / Travel Medicine:

“Malaria prophylaxis is indicated in pregnant women traveling to endemic regions. The risk of severe malaria and poor fetal outcomes is high.”

MCCQE1 Objectives (Public Health > 65-3: Travel Medicine and Pregnancy):

“Candidates must provide preventive care to pregnant travelers including vaccination and malaria prophylaxis.”

Tetanus boosters (D) are given every 10 years. Hep B Ig (B) is for acute post-exposure prophylaxis. Ciprofloxacin (C) is contraindicated in pregnancy.

The most important pre-vaccination history to elicit is any previous anaphylaxis to vaccine components. mRNA COVID-19 vaccines (e.g., Pfizer-BioNTech and Moderna) may contain polyethylene glycol (PEG), a potential allergen. This is a contraindication to administration.

Toronto Notes 2023 – Infectious Disease & Immunization Chapter:

“Absolute contraindications to mRNA COVID-19 vaccination include a documented anaphylactic reaction to a component of the vaccine such as polyethylene glycol (PEG).”

MCCQE1 Objectives – Population Health > Preventive Medicine > Immunizations:

“The candidate must be able to assess for contraindications prior to immunization, including anaphylaxis to previous vaccines or components.”

Breastfeeding and occupational exposure (Options B and D) do not preclude vaccination. Current immunosuppression (Option C) may affect vaccine efficacy but is not a contraindication unless specifically advised.

====================================================

The symptoms — visual hallucinations, attention deficits, gait instability — suggest dementia with Lewy bodies (DLB), which may show bilateral frontal or parietal atrophy on imaging.

Toronto Notes 2023 – Psychiatry, Neurocognitive Disorders:

“DLB presents with fluctuating cognition, visual hallucinations, parkinsonism, and attention deficits. Imaging may show frontal or parietal atrophy but is not always specific.”

MCCQE1 Objectives – Psychiatry > Neurocognitive Disorders:

“Candidates must recognize the characteristic features of DLB and support diagnosis with imaging when appropriate.”

Cerebellar atrophy (A) is linked to ataxia but not hallucinations. Subdural hematoma (B) causes abrupt decline. Mediotemporal atrophy (D) is typical of Alzheimer’s. Option E is incorrect — imaging can support the diagnosis.

Comprehensive and Detailed Explanation:

Cognitive behavioral therapy (CBT) is the most effective first-line treatment for somatic symptom disorder. It helps patients reframe dysfunctional thoughts and improve coping strategies for perceived physical symptoms.

Toronto Notes 2023 – Psychiatry, “Somatic Symptom and Related Disorders”:

“CBT is first-line for somatic symptom disorder. Antidepressants may be considered if comorbid depression or anxiety is present.”

MCCQE1 Objectives (Psychiatry > 71-2: Somatic Symptom Disorders):

“Candidates must manage somatic symptom disorder with appropriate psychosocial interventions.”

Citalopram (B) or amitriptyline (E) may be used adjunctively if mood symptoms are prominent. Risperidone (C) and ERP (D) are not indicated.

—

Comprehensive and Detailed Explanation:

This patient presents with the classic triad of normal pressure hydrocephalus (NPH): gait disturbance (often wide-based and magnetic), cognitive decline, and urinary incontinence. The combination, especially with the gait being most prominent, is highly suggestive.

Toronto Notes 2023 – Geriatrics / Neurology:

“NPH presents with gait disturbance, dementia, and urinary incontinence. Gait is typically broad-based and magnetic. Imaging shows ventriculomegaly without elevated pressure.”

MCCQE1 Objectives (Geriatrics > 41-1: Cognitive Disorders):

“Candidates must identify NPH and distinguish it from other dementias based on clinical triad and gait features.”

Alzheimer’s (B) primarily presents with memory loss. Parkinson’s (A) has bradykinesia and rigidity. Lewy body dementia (C) includes visual hallucinations and fluctuating cognition. FTD (E) has personality and behavioral changes.

====================================================

Comprehensive and Detailed Explanation:

Providing clinical advice (particularly treatment advice) without formally seeing or evaluating the patient creates a physician-patient relationship, potentially establishing a duty of care. If the advice leads to harm, you could be found liable, even if you never saw the patient directly.

Toronto Notes 2023 – Legal Medicine:

“Giving specific medical advice about diagnosis or treatment may imply a physician-patient relationship and establish duty of care.”

MCCQE1 Objectives (ELOM > 90-2: Legal Risk Management):

“Candidates must understand that liability can arise from informal consultations where medical advice is given.”

Providing advice (D) is riskier than simply hearing about a case or patient (A, C). Recommending consultation (B) does not establish duty of care. Not seeing the patient (E) does not automatically shield from liability if treatment advice was given.

—

Comprehensive and Detailed Explanation:

Mid-cycle acute onset pelvic pain with localized adnexal tenderness in a reproductive-age woman suggests a hemorrhagic ovarian cyst, particularly a ruptured one. The hemodynamic parameters are stable, but elevated HR supports acute pain and possible blood loss.

Toronto Notes 2023 – Gynecology / Acute Pelvic Pain:

“Hemorrhagic ovarian cysts present with sudden unilateral pelvic pain, mid-cycle, with guarding and rebound tenderness. Ultrasound is key.”

MCCQE1 Objectives (Gynecology > 82-4: Acute Pelvic Pain):

“Candidates must recognize common causes of acute pelvic pain, including ovarian cysts.”

Diverticulitis (A) is rare in young women and usually LLQ. Appendicitis (B) is more likely RLQ. Adenomyosis (C) and endometriosis (D) cause chronic cyclical pain, not acute tenderness.

—

This patient exhibits classic symptoms of a major depressive episode (MDE): anhedonia, low mood, social withdrawal, feelings of worthlessness, hypersomnia, and loss of appetite. These symptoms are persistent and pervasive beyond what is typical in grief.

Toronto Notes 2023 – Psychiatry, “Depressive Disorders” Section:

“MDE is characterized by ≥5 symptoms present nearly every day for ≥2 weeks including low mood, anhedonia, sleep/appetite disturbances, low energy, feelings of worthlessness, and suicidal ideation. It must cause significant impairment in functioning.”

MCCQE1 Objectives (Psychiatry > 79-1: Mood Disorders):

“Candidates must distinguish between grief, adjustment disorders, and major depression in patients with chronic illness and initiate appropriate management.”

Normal grief (A) may involve sadness and crying but does not involve pervasive hopelessness or worthlessness. Side effects of chemotherapy (C) and hepatic encephalopathy (E) have other specific physical signs. Brain metastasis (D) would more likely present with focal neurologic symptoms or cognitive impairment.

====================================================

The most appropriate and professional response is to focus on the current clinical situation and reassure the family that you will take responsibility for assessment and treatment. Criticizing a colleague (A, B, E) or deflecting to generalities (D) is unprofessional and unhelpful in crisis management.

Toronto Notes 2023 – Psychiatry, Physician-Patient-Family Communication:

“In emotionally charged or crisis situations, the physician must remain focused, empathetic, and professional. Avoid blaming colleagues; instead, offer a concrete plan of care.”

MCCQE1 Objectives – Psychiatry > Ethics and Professionalism:

“Candidates must demonstrate professionalism in managing conflicts, focusing on patient care while maintaining collegial respect.”

====================================================

The findings of exophthalmos (bulging eyes), conjunctival inflammation, and periorbital swelling are hallmark features of Graves ophthalmopathy, a manifestation of autoimmune hyperthyroidism.

Toronto Notes 2023 – Endocrinology, “Thyroid Disorders”:

“Graves ophthalmopathy: proptosis, periorbital edema, conjunctivitis, and diplopia due to extraocular muscle involvement. Often independent of thyroid levels.”

MCCQE1 Objectives (Internal Medicine > 36-1: Thyroid Disease):

“Candidates must recognize and manage Graves disease and its ocular manifestations.”

Myasthenia gravis may cause diplopia but not proptosis or swelling. Pseudotumor and cellulitis are painful and acute. Allergic conjunctivitis is itchy but lacks proptosis.

Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia, especially in patients with impaired renal function. Hyperkalemia can lead to life-threatening arrhythmias, particularly wide complex tachycardia or ventricular fibrillation.

Toronto Notes 2023 – Cardiology and Nephrology, “Hyperkalemia” Section:

“Patients with CKD are at increased risk for hyperkalemia, particularly when taking potassium-sparing medications such as spironolactone. Severe hyperkalemia may cause bradycardia or wide-complex tachyarrhythmias.”

MCCQE1 Objectives (Internal Medicine > 76-2: Electrolyte Abnormalities):

“Candidates must recognize drug-induced hyperkalemia as a cause of cardiac arrhythmias, especially in patients with renal dysfunction.”

Hydrochlorothiazide (B) can cause hypokalemia. Metoprolol (C) and diltiazem (E) are rate-controlling agents but do not typically cause wide complex tachycardia. Clopidogrel (D) has no effect on cardiac conduction.

====================================================

An empty uterus with β-hCG >1500–2000 IU/L raises concern for a pregnancy of unknown location (PUL), including the possibility of ectopic pregnancy. However, the patient is hemodynamically stable and asymptomatic. In such cases, the best initial step is to repeat serum β-hCG in 48 hours to assess the rise or fall of hCG levels.

Toronto Notes 2023 – Obstetrics, "First Trimester Bleeding":

“If β-hCG >1500 IU/L and no intrauterine pregnancy is visualized on ultrasound, repeat β-hCG in 48 hours to determine rise or decline. A suboptimal rise (less than 66%) suggests ectopic pregnancy.”

MCCQE1 Objectives (Obstetrics > 79-1: Early Pregnancy Complications):

“In a patient with early pregnancy bleeding, the candidate must interpret quantitative β-hCG trends to distinguish ectopic pregnancy, miscarriage, or viable intrauterine pregnancy.”

Immediate administration of methotrexate or invasive procedures such as D&C or laparoscopy are not appropriate until further diagnostic clarification is obtained.

====================================================

This presentation describesnormal developmental dysfluency, which typically occurs between ages 2–5 and often worsens duringtimes of stress or change, such as a new sibling. It is characterized byword repetitionand does not require intervention unless it persists >6 months, worsens, or causes distress.

Toronto Notes 2023 – Pediatrics, "Developmental and Behavioral Pediatrics" Section:

“Developmental stuttering is common between 2–5 years and often resolves without intervention. Reassurance is appropriate unless there are signs of persistent or severe stuttering, secondary behaviors, or parental concern.”

MCCQE1 Objectives (Pediatrics > 78-1: Development and Behavior):

“Candidates must recognize typical patterns of developmental speech dysfluency and differentiate them from pathological speech disorders. Observation and reassurance are often the appropriate initial step.”

Because the child is otherwise developing normally and the onset coincides with a known psychosocial stressor,reassuranceis the most appropriate step. Formal speech or behavioral therapy is not indicated at this time.

Physicians in Canada who have conscientious objections to procedures such as abortion are legally and ethically required to make an effective referral to another provider or service that can offer the treatment. The provider must not delay access to care.

Toronto Notes 2023 – ELOM, “Conscientious Objection”:

“A physician who objects to providing a service for reasons of conscience must make an effective referral to another provider or agency.”

MCCQE1 Objectives (ELOM > Professionalism > 90-1):

“Candidates must recognize the obligation to refer patients for services they themselves will not provide due to personal or religious beliefs.”

Delaying care (C), imposing personal beliefs (A), or suggesting alternatives like adoption (D) is inappropriate and may violate patient autonomy.

====================================================

Oral contraceptives increase the risk of thromboembolic events, particularly in patients with risk factors such as smoking and obesity. However, informing the patient’s partner of potential contributing factors in a factual, non-judgmental manner is appropriate and does not imply fault.

Toronto Notes 2023 – ELOM, “Informed Consent and Risk Communication”:

“Patients and families should be informed of all relevant information, including potential drug-related adverse events. Blame must not be assigned without full investigation.”

MCCQE1 Objectives (ELOM > 90-2: Physician–Patient Communication):

“Candidates must be able to communicate adverse outcomes factually, while respecting confidentiality and without prematurely assigning fault.”

Discussing the case with the ethics committee or reporting the prescribing doctor without context is premature and inappropriate (A, D). Telling the partner the physician was at fault (C) is speculative and unethical.

====================================================

This man exhibits a classic manic episode with psychotic features: persecutory delusions, distractibility, pressured speech, irritability, and possible grandiosity. The chronicity and mood symptoms are most consistent with Bipolar I disorder.

Toronto Notes 2023 – Psychiatry, “Mood Disorders” Section:

“Bipolar I disorder is characterized by episodes of mania, often with psychotic features.Symptoms include grandiosity, decreased need for sleep, distractibility, and mood-congruent delusions.”

MCCQE1 Objectives (Psychiatry > 79-1: Mood Disorders):

“Candidates must recognize mania and differentiate from brief psychosis or organic causes.”

Delirium (A) is acute, fluctuating, and involves impaired attention. Malingering (B) requires external gain. Brief psychotic disorder (C) resolves within 1 month. Brain injury–related psychosis (E) would require a supporting history or findings.

(Part 2 )

One of the strongest modifiable risk factors for postoperative delirium in older adults is exposure to anticholinergic medications (e.g., diphenhydramine, certain antidepressants). Avoiding these can reduce delirium risk.

Toronto Notes 2023 – Geriatrics, “Delirium Prevention”:

“Avoid high-risk medications including anticholinergics, benzodiazepines, and narcotics if possible. Maintain orientation cues and adequate pain control.”

MCCQE1 Objectives (Medicine > Geriatrics > 41-1: Cognitive Impairment):

“Candidates must recognize predisposing factors for delirium and apply prevention strategies, including medication review.”

Opiates (B) should be used judiciously; untreated pain can also cause delirium. Cognitive screening (C) is helpful for baseline but does not prevent delirium. Benzodiazepines (D) increase delirium risk. Family involvement is actually helpful (E).

====================================================

Comprehensive and Detailed Explanation:

Decreased libido in elderly patients can be multifactorial, but depression is a common and important cause that must be ruled out before hormone therapy or other steps. A proper mental health screen should precede further interventions.

Toronto Notes 2023 – Psychiatry / Geriatrics:

“In elderly men, reduced libido may be linked to depression, medical illness, or medications. Depression screening is essential.”

MCCQE1 Objectives (Psychiatry > 71-1: Mood Disorders / Sexual Health):

“Candidates must consider depression as a common cause of decreased libido and assess accordingly before initiating hormone therapy.”

Testosterone testing (D) may follow. Prescribing (C) is premature. Couples counselling (B) may help if interpersonal issues are identified. Interviewing together (A) may inhibit disclosure.

—

Comprehensive and Detailed Explanation:

This patient is pregnant and febrile with a new headache, photophobia, and clonus — all features concerning for preeclampsia with neurologic involvement. Clonus is a key finding suggestive of central nervous system irritability. Urine protein/creatinine ratio helps confirm the diagnosis of preeclampsia.

Toronto Notes 2023 – Obstetrics, Hypertensive Disorders in Pregnancy:

“Headache, clonus, and visual disturbances are concerning for severe preeclampsia. A urine protein/creatinine ratio or 24-hour urine collection confirms diagnosis.”

MCCQE1 Objectives – Obstetrics > Hypertension in Pregnancy:

“Candidates must recognize signs of preeclampsia and assess with appropriate biochemical testing.”

CT (A) or LP (B) are not indicated unless focal neurologic signs or seizures are present. Fetal imaging and amniocentesis (C, D) do not address maternal symptoms.

====================================================

Comprehensive and Detailed Explanation:

Infertility is defined as the inability to conceive after 12 months of regular, unprotected intercourse in women under 35 years. Since she has been trying for only 5 months, reassurance is appropriate.

Toronto Notes 2023 – Gynecology:

“Investigations for infertility in women under 35 should begin after 12 months of attempting to conceive, unless other risk factors are present.”

MCCQE1 Objectives (Gynecology > 82-1: Infertility):

“Candidates must apply appropriate timing and indications for infertility investigations based on patient age and history.”

Earlier testing is not warranted here. Options A–D are part of the infertility work-up but not before 12 months.

====================================================

Comprehensive and Detailed Explanation:

The most appropriate next step for a patient with intermittent palpitations and a normal ECG is Holter monitoring (or event monitoring). This can capture and correlate symptoms with cardiac rhythm.

Toronto Notes 2023 – Cardiology, “Palpitations”:

“Holter or event monitoring is indicated when the initial ECG is normal but the patient has episodic symptoms such as palpitations.”

MCCQE1 Objectives (Cardiology > 34-2: Arrhythmia):

“Candidates must use ambulatory ECG monitoring to investigate intermittent palpitations when resting ECG is unremarkable.”

Echocardiogram (A) assesses structural issues but not rhythm. β-blockers (B) should not be started without diagnosis. Stress testing (D) is for ischemia.

====================================================

Persistent postmenopausal bleeding requires thorough evaluation. An inadequate endometrial biopsy result does not rule out pathology. Hysteroscopy allows for direct visualization and targeted biopsy and is the gold standard when biopsy is non-diagnostic.

Toronto Notes 2023 – Gynecology, “Abnormal Uterine Bleeding and Endometrial Cancer” Section:

“Persistent bleeding with insufficient biopsy requires further evaluation, preferably via hysteroscopy and directed biopsy. This is especially important in patients on HRT or with risk factors for endometrial pathology.”

MCCQE1 Objectives (Obstetrics & Gynecology > 82-9: Postmenopausal Bleeding):

“Candidates must investigate abnormal bleeding in postmenopausal women with hysteroscopy when endometrial sampling is non-diagnostic.”

Changing hormones (A), reducing progestin (E), or performing colposcopy (C) are not appropriate without confirming the cause of bleeding.

====================================================

Comprehensive and Detailed Explanation:

The child’s presentation (weight gain, short stature, truncal obesity, facial swelling, hypertrichosis) is classic for Cushing syndrome. One of the hallmark findings on physical examination in pediatric Cushing syndrome is hypertension, due to increased cortisol-mediated mineralocorticoid receptor activation.

Toronto Notes 2023 – Pediatrics / Endocrinology:

“Cushing syndrome in children presents with growth failure, weight gain, moon facies, truncal obesity, and hypertension.”

MCCQE1 Objectives (Pediatrics > 77-2: Endocrine Disorders in Children):

“Candidates must identify clinical signs of hypercortisolism and evaluate for associated findings such as elevated blood pressure.”

Café-au-lait spots (A) suggest neurofibromatosis. Goiter (C) is more related to thyroid dysfunction. Hepatomegaly (D) and acanthosis (E) are more commonly seen in metabolic syndrome or insulin resistance.

—

Comprehensive and Detailed Explanation:

During mass casualty incidents, effective triage is essential to optimize care delivery. A trained physician is best used in triage or direct care. Triage is the foundation of disaster management.

Toronto Notes 2023 – Public Health / Disaster Medicine:

“In disaster response, trained healthcare providers should be deployed to triage and stabilize patients in emergency departments.”

MCCQE1 Objectives (Public Health > 65-1: Disaster Response):

“Candidates must understand principles of mass casualty management and assign appropriate roles during triage and care delivery.”

Media (D) and logistics (A, C) are secondary roles. Triage and direct care take priority.

====================================================

This is a classic presentation of acute acetaminophen (paracetamol) overdose. The most serious consequence, especially with delayed treatment, is fulminant hepatic failure.

Toronto Notes 2023 – Toxicology, Acetaminophen Toxicity:

“Acetaminophen overdose is the most common cause of acute liver failure. Delayed presentation leads to jaundice, coagulopathy, encephalopathy, and possible death.”

MCCQE1 Objectives – Internal Medicine > Toxicology:

“Candidates must identify acetaminophen overdose by clinical history and recognize fulminant hepatic failure as a primary complication.”

Cerebral edema (C) may occur secondarily, but fulminant hepatic failure is the most direct and expected outcome. Renal failure (B), arrhythmias (E), and seizures (A) are not typical with acetaminophen.

==================================================

Medical record retention is governed by laws and policies established by the provincial or territorial medical regulatory authorities (e.g., College of Physicians and Surgeons of Ontario).These bodies set requirements for how long patient records must be maintained and how to handle former patients’ data.

Toronto Notes 2023 – Ethics and Health Systems:

“Retention of medical records is regulated by provincial/territorial colleges, which outline minimum retention periods and storage responsibilities.”

MCCQE1 Objectives (ELOM > Legal Requirements > Professional Responsibilities):

“The candidate must be able to identify the legal responsibilities of physicians regarding record-keeping, as guided by regulatory authorities.”

National organizations such as Health Canada, CFPC, CMA, and MCC do not set these rules for individual practice management.

====================================================

Persistent bloody diarrhea with negative stool cultures and ova/parasite testing in an older adult suggests inflammatory bowel disease (IBD) or another colitis such as ischemic or microscopic colitis. Colonoscopy is the best next diagnostic step to evaluate for ulcerative colitis, Crohn disease, ischemic colitis, or malignancy.

Toronto Notes 2023 – Gastroenterology, "Inflammatory Bowel Disease":

“Persistent bloody diarrhea with negative infectious work-up should prompt colonoscopic evaluation to rule out IBD or other forms of colitis.”

MCCQE1 Objectives (Internal Medicine > Gastrointestinal > 47-1):

“Candidates must assess and investigate chronic or persistent diarrhea. In the presence of red flag features such as bleeding, weight loss, or anemia, colonoscopy is indicated.”

Antibiotics (A) are not indicated with negative stool cultures. Observation (C) and loperamide (D) risk delaying diagnosis. Steroids (E) may be required later but only after confirmation of diagnosis.

Comprehensive and Detailed Explanation:

Transient synovitis is the most common cause of hip pain and limp in children aged 3–10 years. It is often preceded by a viral infection. Patients appear well, can often bear weight, and have only mild to moderate elevation in inflammatory markers. Radiographs are normal.

Toronto Notes 2023 – Pediatrics, “Limping Child”:

“Transient synovitis is benign and self-limiting. Presentation includes mild limp, low-grade fever, normal or slightly elevated CRP/ESR, and ability to bear weight.”

MCCQE1 Objectives (Pediatrics > 78-2: Musculoskeletal Disorders):

“Candidates must distinguish between transient synovitis and more serious causes of limping, such as septic arthritis.”

Septic arthritis (A) usually causes inability to bear weight and more significant fever and CRP elevation. Osteomyelitis (B) typically presents with localized tenderness and systemic signs. Bursitis (D) is rare in young children. JIA (E) is chronic.

—

Respecting patient autonomy requires understanding their perspective before offering persuasion or incentives. The best next step is to explore the reason for non-compliance. This builds rapport and informs a shared decision-making process.

Toronto Notes 2023 – ELOM, Patient-Centered Communication:

“When a patient refuses recommended treatment, explore the reason behind the refusal before proceeding. Shared decision-making is crucial.”

MCCQE1 Objectives – ELOM > Communication and Consent:

“Candidates must demonstrate an ability to explore reasons for treatment refusal before counseling or modifying management.”

Options B and C may follow later. Options D and E can undermine appropriate pharmacologic care or violate ethics if not consented.

====================================================

Given the request for opioids and history of non-prescribed opioid use (oxycodone obtained from a friend), the next appropriate step is to conduct a urine drug screen. This helps assess current substance use and guides safe prescribing decisions.

Toronto Notes 2023 – Pain Management and Addiction Medicine:

“Urine drug screening is recommended before initiating opioid therapy or when there is suspicion of substance misuse. A history of using non-prescribed opioids mandates assessment for opioid use disorder and further risk stratification.”

MCCQE1 Objectives – Internal Medicine > Chronic Pain:

“Candidates must assess for opioid misuse and dependence before initiating opioid therapy. Urine drug testing is a standard tool in this assessment.”

Providing naloxone (A) may be appropriate later if opioids are prescribed, but the priority is evaluation. Cannabis (B) is not first-line and lacks controlled evidence in chronic pain. Tramadol (D) is an opioid-like agent and not appropriate until misuse risk is evaluated.

Primary herpetic gingivostomatitis caused by HSV-1 is common in toddlers. It presents with high fever, irritability, drooling, refusal to eat, and painful oral ulcers on the lips, gums, and tongue. Cervical lymphadenopathy is common.

Toronto Notes 2023 – Pediatrics, “Infectious Conditions in Children”:

“Primary HSV-1 infection in children presents with high fever, cervical lymphadenopathy, and painful oral ulcers (gingivostomatitis).”

MCCQE1 Objectives (Pediatrics > 75-2: Infectious Diseases):

“Candidates must recognize viral exanthems and enanthems, including herpetic gingivostomatitis, based on clinical findings.”

Kawasaki (A) includes conjunctivitis, strawberry tongue, and extremity changes. Epiglottitis (B) presents with drooling but without oral ulcers. Mono (C) lacks the ulcerative pattern. Hand-foot-mouth (D) affects palms and soles, not inner lips and gums predominantly.

====================================================

Comprehensive and Detailed Explanation:

Physicians must be transparent and honest in documentation. If a previous abnormality was missed, it must be acknowledged. The correct action is to comment on both the previous and current findings in your report and follow institutional disclosure policies.

Toronto Notes 2023 – ELOM, “Medical Error and Disclosure”:

“Physicians must report and document prior missed findings honestly and provide full disclosure when reviewing comparative studies.”

MCCQE1 Objectives (ELOM > 90-2: Accountability and Communication):

“Candidates must accurately document previous findings when reviewing comparative data, even if it reveals past oversight.”

Delaying reporting (C–E) or omitting prior findings (A) is unethical.

—

The description is classic for metatarsus adductus. The most important clinical factor guiding management is whether the foot is flexible or rigid. Flexible deformities typically resolve spontaneously and do not require intervention.

Toronto Notes 2023 – Pediatrics, “Musculoskeletal Conditions”:

“Metatarsus adductus: inward deviation of the forefoot. Management depends on flexibility. Flexible cases are benign and resolve spontaneously; rigid forms may need casting.”

MCCQE1 Objectives (Pediatrics > 78-2: Musculoskeletal Disorders):

“Candidates must assess and differentiate between flexible and rigid deformities to guide treatment in foot abnormalities.”

Other findings (B–E) are either unrelated or not determinant in metatarsus adductus management.

—

Comprehensive and Detailed Explanation:

This patient likely has treatment-resistant obsessive-compulsive disorder (OCD), with classicsymptoms of rumination, excessive guilt, and fear of causing harm. Clomipramine, a tricyclic antidepressant with strong serotonergic activity, is effective in treatment-resistant OCD and is often used after failure of multiple SSRIs or SNRIs.

Toronto Notes 2023 – Psychiatry, OCD:

“Clomipramine is a first-line tricyclic antidepressant for OCD, particularly after failed SSRI/SNRI trials. It is effective due to potent serotonergic action.”

MCCQE1 Objectives – Psychiatry > OCD and Anxiety Disorders:

“Candidates must identify treatment strategies for resistant OCD, including the role of clomipramine and augmentation therapy.”

Quetiapine (C) may be used as augmentation. Paroxetine (E) is another SSRI. Vortioxetine (A) and amitriptyline (D) are not first-line or preferred for OCD.

This child presents with “red flag” features for malignancy: a firm, fixed, nontender supraclavicular lymph node >2 cm in size, with associated hepatosplenomegaly and night sweats. These features are most concerning for lymphoma.

Toronto Notes 2023 – Pediatrics, “Lymphadenopathy in Children”:

“Malignant lymphadenopathy tends to be firm, fixed, painless, and located in supraclavicular areas. Systemic signs (fever, weight loss, hepatosplenomegaly, night sweats) are concerning for lymphoma.”

MCCQE1 Objectives (Pediatrics > 78-3: Hematology/Oncology):

“Candidates should differentiate between benign and malignant lymphadenopathy and recognize features suggestive of lymphoma.”

Cat-scratch disease (B) is usually tender and associated with cat exposure. Kawasaki disease (C) presents with fever and mucocutaneous findings. Acute bacterial lymphadenitis (D) is painful, warm, and rapid in onset. Viral lymphadenopathy (E) is often bilateral, small, and tender.

====================================================

Comprehensive and Detailed Explanation:

The levonorgestrel-releasing intrauterine device (LNG-IUD) is generally contraindicated in current or recent breast cancer due to the progestin component, but may be considered in selectpatients on tamoxifen, especially if non-hormonal options are unsuitable. Consultation with the oncologist is required to evaluate risks and benefits.

Toronto Notes 2023 – Gynecology, “Contraception in Special Populations”:

“Levonorgestrel IUDs are generally avoided in patients with a history of hormone-sensitive cancers; however, decisions should be made collaboratively with oncology.”

MCCQE1 Objectives (Gynecology > 82-2: Contraception):

“Candidates must tailor contraceptive advice to patients with medical comorbidities, including cancer survivors.”

Irregular bleeding (A) is a common but not contraindicating side effect. No pre-procedure antibiotics (D) are typically needed. The IUD does not cause infertility (E). Risk of recurrence (C) is unconfirmed and must be individualized.

—

Elevated hemoglobin in the absence of polycythemia vera can be due to secondary causes such as chronic hypoxia. Central sleep apnea, often associated with diabetes or neurologic conditions, leads to intermittent hypoxia and compensatory erythropoiesis.

Toronto Notes 2023 – Hematology and Respiratory Medicine, “Polycythemia” Section:

“Secondary erythrocytosis may result from hypoxic conditions including sleep apnea, COPD, or high altitude. Assess for sleep-disordered breathing in patients with elevated hemoglobin and no myeloproliferative features.”

MCCQE1 Objectives (Internal Medicine > 76-7: Hematologic Abnormalities):

“Candidates must investigate secondary causes of elevated hemoglobin, including hypoxia-related conditions.”

Hypertension (A), hypothyroidism (C), and cirrhosis (D) do not cause polycythemia. Alcohol (B) typically causes macrocytosis and anemia.

Comprehensive and Detailed Explanation:

Pulsatile tinnitus synchronous with the pulse may be vascular in origin. The association with headaches and elevated BMI (a risk factor for idiopathic intracranial hypertension, IIH) warrants neuroimaging to assess for cerebral venous sinus thrombosis, vascular malformations, or raised intracranial pressure.

Toronto Notes 2023 – Neurology / ENT:

“Pulsatile tinnitus requires investigation for vascular causes including idiopathic intracranial hypertension. MRI or MRV is the next step.”

MCCQE1 Objectives (Neurology > 35-1: Headache and Tinnitus):

“Candidates must investigate pulsatile tinnitus with neuroimaging when vascular causes are suspected.”

Audiogram (A) is for hearing loss. EEG (C) is not useful for tinnitus. CRP (D) is irrelevant.

====================================================

The most important factor in determining the surveillance interval in Barrett esophagus is the presence and grade of dysplasia (e.g., none, low-grade, high-grade). High-grade dysplasia requires more frequent monitoring or intervention due to the risk of progression to esophageal adenocarcinoma.

Toronto Notes 2023 – Gastroenterology, Barrett Esophagus:

“Surveillance intervals depend on histologic findings. No dysplasia: q3–5 years; low-grade: q6–12 months; high-grade: consider endoscopic resection or ablation.”

MCCQE1 Objectives – Internal Medicine > Gastroenterology:

“Candidates must identify the risk of progression in Barrett esophagus and apply appropriate surveillance strategies based on dysplasia.”

Length of the segment (A) may influence risk but not surveillance frequency alone. Other options (B, C, E) are less determinative.

====================================================

A varicocele is a dilatation of the pampiniform plexus that presents with a “bag of worms” appearance, worsens with standing, and improves when lying down. It is most common on the left side due to anatomical drainage differences.

Toronto Notes 2023 – Urology, Scrotal Disorders:

“Varicoceles often present with a dull, aching pain and scrotal swelling that worsens when upright and disappears when supine.”

MCCQE1 Objectives – Internal Medicine > Urology:

“Candidates must recognize and diagnose varicocele by physical exam findings and typical symptom history.”

Cryptorchidism (A) refers to undescended testes. Torsion (B) presents acutely with severe pain. Hydrocele (C) transilluminates and is not posture-dependent. "Spermatocyte" (D) is not a clinical diagnosis.

====================================================

This patient has a family history of both male breast cancer (father) and early-onset ovarian cancer (aunt), which are red flags for BRCA1/2 mutations. Genetic counseling and BRCA testing are the appropriate next steps to stratify cancer risk and guide screening and prevention.

Toronto Notes 2023 – Oncology, “Breast Cancer Risk” Section:

“BRCA testing is recommended for individuals with a strong family history of breast or ovarian cancer, particularly if involving male relatives or early-onset cases.”

MCCQE1 Objectives (Population Health > 97-5: Screening and Prevention):

“Candidates must identify high-risk individuals who require genetic counseling and screening beyond population guidelines.”

Tamoxifen (A) and prophylactic mastectomy (E) are only considered after confirming mutation status. Annual screening starting at 50 (D) is for average-risk women. Fine-needle sampling (C) is not a screening tool.

====================================================

Comprehensive and Detailed Explanation:

An estimated fetal weight below the 5th percentile at 30 weeks is concerning for intrauterine growth restriction (IUGR). This warrants prompt evaluation of fetal well-being via biophysical profile and Doppler assessment. The patient should be referred for further fetal assessment immediately to rule out placental insufficiency or other complications.

Toronto Notes 2023 – Obstetrics, “Fetal Growth Restriction”:

“EFW < 10th percentile, especially < 5th, warrants further evaluation including Doppler studies and biophysical profile. Immediate assessment is warranted to determine fetal well-being.”

MCCQE1 Objectives (Obstetrics > 80-4: Antepartum Surveillance):

“Candidates must initiate urgent assessment in cases of abnormal fetal growth to reduce perinatal morbidity.”

Delaying care (B) is inappropriate. Reassurance (A) is unsafe. ASA (D) is preventative, not corrective. Doppler (E) is important but should be coordinated through obstetrical triage.

====================================================

During an outbreak in a long-term care facility, prompt control measures include keeping symptomatic staff at home to prevent spread. Staff are often vectors of infection, and exclusion is a key public health intervention.

Toronto Notes 2023 – Infectious Diseases, “Infection Control and Prevention”:

“During influenza outbreaks in institutional settings, exclusion of symptomatic staff is critical to controlling spread.”

MCCQE1 Objectives (Population Health > 63-2: Outbreak Management):

“Candidates must understand outbreak control, including staff exclusion, cohorting, and surveillance in congregate settings.”

Vaccination (B) is preventive but not immediately effective during an outbreak. Masking and visitor vaccination are supportive but secondary measures.

This is a known patient with intellectual disability and behavioral concerns. The presentation of alcohol intoxication in a calm patient who inadvertently broke bottles warrants prompt, nonjudgmental clinical assessment before escalating. De-escalation and safety assessment come first.

Toronto Notes 2023 – Psychiatry, "Psychiatric Emergencies and Crisis Management":

“In agitated or intoxicated individuals with developmental disability, a calm approach and prompt physician assessment are essential to prevent escalation and assess for medical or psychiatric needs.”

MCCQE1 Objectives (Psychiatry > Crisis and Acute Presentations > 72-2):

“Candidates must assess potentially disruptive patients with dignity and caution before involving law enforcement or security. Physician engagement is often calming.”

Police intervention (A) is premature and may escalate matters. Ignoring (B) risks safety. Asking him to leave (C) without assessment is inappropriate. Social work (E) may help, but after medical triage.

This patient’s lab results suggest impaired fasting glucose and an elevated A1c just below the threshold for diabetes. The gold standard to confirm diabetes in such intermediate cases is the 75 g oral glucose tolerance test (OGTT).

Toronto Notes 2023 – Endocrinology, “Diabetes Mellitus” Section:

“If A1c is in the 6.0–6.4% range or fasting glucose 6.1–6.9 mmol/L, a 75 g OGTT is recommended to establish the diagnosis of diabetes or confirm impaired glucose tolerance.”

MCCQE1 Objectives (Internal Medicine > 76-4: Diabetes):

“Candidates must correctly apply diabetes screening and diagnostic criteria and follow up abnormal results with appropriate confirmatory testing.”

Urine ACR (C) is useful in diagnosed diabetes, not for initial screening. TSH (A), capillary glucose testing (B), and exercise testing (E) are not indicated at this stage.

====================================================

Comprehensive and Detailed Explanation:

The patient is in a persistent vegetative state and medically stable, meaning he does not need continued hospitalization. The goal is to provide appropriate long-term care in the least restrictive setting, typically at home with robust home care support services. This approach aligns with ethical care, family-centered goals, and medical appropriateness.

Toronto Notes 2023 – Pediatrics / Neurodevelopment & Chronic Care:

“Home care with appropriate medical and caregiver support is often the best setting for children with severe neurological impairments who are medically stable.”

MCCQE1 Objectives (Pediatrics > 77-5: Chronic Neurological Disorders):

“Candidates must assess discharge planning and coordinate home care support for children with long-term care needs.”

Palliative facility (B) is not appropriate unless end-of-life is imminent. School (C) is not feasible in this state. Hospital readmission for respite (D) is not standard. Rehabilitation (E) has little utility in persistent vegetative state.

Comprehensive and Detailed Explanation:

This neonate likely has gonococcal conjunctivitis, which typically presents 2–5 days after birth with bilateral purulent discharge and swelling. This is an emergency due to the risk of corneal perforation. Empiric IV antibiotics and hospital admission are indicated.

Toronto Notes 2023 – Pediatrics, Neonatal Infections:

“Neonatal conjunctivitis within the first 1–2 weeks should raise suspicion for gonococcal or chlamydial infection. Gonorrhea requires urgent IV antibiotics and hospitalization.”

MCCQE1 Objectives – Pediatrics > Neonatal Infection:

“Candidates must recognize neonatal conjunctivitis and initiate empiric treatment while awaiting culture results.”

Lacrimal massage (E) and warm compresses (D) are used for nasolacrimal duct obstruction. Oral or topical antibiotics (B, C) are insufficient for suspected gonococcal infection.

====================================================

This patient has classic signs of cardiac tamponade (Beck's triad: hypotension, muffled heartsounds, elevated JVP, plus pulsus paradoxus). However, she also has advanced metastatic cancer, functional decline, and has stopped active treatment. In this context, a goals-of-care discussion is the most appropriate next step to determine her wishes regarding interventions like pericardiocentesis.

Toronto Notes 2023 – Palliative Care:

“End-of-life care should prioritize quality of life and patient preferences. In patients with terminal illness and life-threatening conditions (e.g., tamponade), initiate a conversation about goals before aggressive intervention.”

MCCQE1 Objectives – Internal Medicine > Palliative and End-of-Life Care:

“Candidates must assess prognosis, patient values, and initiate appropriate end-of-life discussions before invasive treatment.”

Although pericardiocentesis (A) may relieve symptoms, it should follow consent based on the patient’s goals. ICU (E), fluids (B), or transfusion (D) are not appropriate without this discussion.

According to Canadian guidelines, women aged 50 to 74 at average risk for breast cancer should undergo routine screening mammography every 2 to 3 years. A great-aunt with breast cancerdoes not raise this patient's risk to high. Mammography is appropriate as she is now due for the next screen.

Toronto Notes 2023 – Population Health, “Screening Guidelines” Section:

“Routine mammography is recommended every 2 years for average-risk women aged 50 to 74. Family history in second-degree or more distant relatives (e.g., great-aunt) does not qualify for high-risk screening or MRI.”

MCCQE1 Objectives (Population Health > 97-5: Screening and Prevention):

“Candidates should apply Canadian screening recommendations including mammography for average-risk women ≥50 years old.”

Self-breast exams (C) are not recommended for screening. PET scan (D) and MRI (E) are reserved for high-risk populations or diagnostic clarification.

====================================================

The clinical presentation ofmultiple fractures at different stages of healingin a young child raisesstrong suspicion of physical abuse(non-accidental trauma). In such situations,mandatory reporting to child protection services is legally and ethically required, even in the absence of parental admission or clear history.

Toronto Notes 2023 – Pediatrics, Child Maltreatment Section:

“Red flags include inconsistent history, delay in seeking care, multiple injuries in various stages of healing, and injuries not consistent with developmental level. Health care professionals arelegally obligatedto report suspected child abuse or neglect to child protection authorities without delay.”

MCCQE1 Objectives (Medical Expert > Pediatrics > 77-2):

"The candidate must be able to recognize when the findings are consistent with child abuse... When child abuse is suspected,the physician has a legal obligation to report to the appropriate child protection agencyimmediately."

Options B, C, D, and E do not address the immediate child safety risk and legal duty. Social work involvement (E) is supportive but must follow or accompany notification to child protection, not replace it.

The first step in any MAID request is to explore the patient's motivations, psychosocial concerns, and mental health status. The request should be taken seriously and approached with compassion. Exploring the reasons is essential to determine eligibility and to distinguish suffering from other potentially treatable issues (e.g., depression, loss of hope).

Toronto Notes 2023 – ELOM, "Medical Assistance in Dying":

“Upon receiving a request for MAID, the physician must first explore the patient’s motivations, ensure understanding of their condition, and assess for coercion, depression, or other treatable factors.”

MCCQE1 Objectives (ELOM > Ethical Dilemmas > End-of-Life Care):

“Candidates must demonstrate understanding of the ethical and legal framework surrounding MAID and respond appropriately to requests by exploring reasons and providing necessary support and referrals.”

MAID is available to mature minors in some jurisdictions but not uniformly. Assuming the patient is ineligible or redirecting to other treatments without discussion is inappropriate.

====================================================

This patient exhibits perfectionism, preoccupation with order and control, and reluctance to delegate — classic features of obsessive-compulsive personality disorder (OCPD). Unlike OCD, there are no intrusive thoughts or compulsions; rather, behaviors are ego-syntonic.

Toronto Notes 2023 – Psychiatry, Personality Disorders:

“OCPD is marked by perfectionism, rigidity, and preoccupation with productivity. It differs from OCD in lacking obsessions or compulsions.”

MCCQE1 Objectives – Psychiatry > Personality Disorders:

“Candidates must distinguish OCPD by traits of excessive perfectionism, control, and inflexibility, particularly when these interfere with functioning.”

Major depression (A) is marked by pervasive low mood, which is not reported. OCD (B) involves distressing obsessions and compulsions. GAD (C) is more generalized worry without the perfectionism and rigidity.

====================================================

In cross-cultural care, especially for recent immigrants, it is essential to build rapport and respect patient preferences regarding family involvement. Involving family in the interview respects cultural norms and improves trust. A trained interpreter should be used to maintain confidentiality and accuracy, but collaboration with the family initially may encourage later private disclosure.

Toronto Notes 2023 – Ethics and Communication, “Cultural Competence”:

“When encountering language or cultural barriers, patient comfort and cultural context must be respected. Interviewing the patient and family together may facilitate trust, after which individual conversations may be possible.”

MCCQE1 Objectives (ELOM > 90-1: Communication and Patient-Centered Care):

“Candidates must approach patients in a culturally sensitive manner, particularly recent immigrants or those with language barriers, and foster trust.”

Insisting on a private interview (A) may alienate the patient. Family members should not act as interpreters (C). Written accounts (D) are inefficient and impersonal in acute mental health settings.

====================================================

Comprehensive and Detailed Explanation:

Ginger is a first-line, evidence-based non-pharmacologic treatment for nausea and vomiting in pregnancy. It's well tolerated and effective. Addressing nausea will help her resume vitamin use and reduce distress.

Toronto Notes 2023 – Obstetrics, “Nausea and Vomiting in Pregnancy”:

“Ginger 250 mg four times daily is safe and effective for mild to moderate nausea.”

MCCQE1 Objectives (Obstetrics > 80-1: Early Pregnancy Management):

“Candidates must treat nausea and vomiting in pregnancy using safe and effective options.”

Folic acid alone (A) is less effective than a full prenatal vitamin. B may help, but nausea should be addressed first. C lacks empathy for her symptoms. D (cannabinoids) is not recommended in pregnancy.

This presentation suggests hereditary hemochromatosis. Common features include hyperpigmentation ("bronze diabetes"), hepatomegaly, diabetes, fatigue, and elevated liver enzymes. Serum ferritin is a screening test for iron overload, and elevated levels support the diagnosis.

Toronto Notes 2023 – Endocrinology / Gastroenterology:

“Hemochromatosis presents with skin hyperpigmentation, hepatomegaly, diabetes, fatigue. Diagnosis begins with serum ferritin and transferrin saturation.”

MCCQE1 Objectives (Internal Medicine > Metabolic and Endocrine > 37-1):

“Candidates must investigate iron overload syndromes using ferritin and transferrin saturation.”

Cortisol (B) is for adrenal insufficiency. A1AT (C) is a liver disease cause but not typical here. Amylase (E) is for pancreatitis. A1c (A) would confirm diabetes but not the underlying cause.

====================================================

Microcephaly, intrauterine growth restriction, hepatosplenomegaly, and normal vital signs in a term newborn strongly suggest congenital viral infection (e.g., CMV, toxoplasmosis, rubella).

Toronto Notes 2023 – Pediatrics, Congenital Infections:

“Signs of congenital TORCH infections include microcephaly, hepatosplenomegaly, and growth restriction. Early identification is key.”

MCCQE1 Objectives – Pediatrics > Infectious Disease:

“Candidates must recognize signs suggestive of congenital infections and distinguish from genetic or structural abnormalities.”

Cephalic molding (A) is benign and resolves spontaneously. Lipid storage diseases (B) are not present at birth. Cystic fibrosis (C) does not cause microcephaly or hepatosplenomegaly at birth. Trisomy 21 (D) has distinct dysmorphic features not described here.

====================================================

Spontaneous, unilateral, blood-tinged nipple discharge in a postmenopausal woman is considered pathologic and warrants imaging to rule out intraductal pathology including malignancy. The best initial test is diagnostic mammography, often with ultrasound if indicated.

Toronto Notes 2023 – Breast Disorders:

“Unilateral, spontaneous, bloody nipple discharge should be evaluated with mammography and targeted ultrasound. Further tests such as MRI or duct excision are based on findings.”

MCCQE1 Objectives (Gynecology > 81-1: Breast Conditions):

“Candidates must recognize red flags for breast malignancy and apply appropriate initial diagnostic imaging.”

Serum prolactin (C) is indicated in galactorrhea. Galactography (D) and MRI (E) are second-line. Biopsy (A) is premature without imaging.

Given the lack of prenatal care, the mother's withdrawal, and prior involvement of child protection services, a newborn drug screen is warranted to assess for possible in utero exposure. This is part of the safety assessment.

Toronto Notes 2023 – Pediatrics, Newborn Assessment:

“Infants born to mothers with no prenatal care or prior social concerns should undergo a full newborn screening, including toxicology if indicated.”

MCCQE1 Objectives – Pediatrics > Newborn Care and Social Issues:

“Candidates must identify social risk factors and initiate appropriate newborn evaluations, including toxicology screens when substance use is suspected.”

The mother was previously immune to hepatitis B, so (A) is not immediately required. Skin-to-skin care (D) is beneficial but secondary to screening in this context. Donor milk (B) is not indicated unless breastfeeding is contraindicated.

====================================================

In situations involving potential oversight, the appropriate next step is to contact the other physician directly. This supports collegial communication, continuity of care, and provides an opportunity to clarify the clinical situation. It avoids premature judgment while allowing the primary provider to respond and address concerns.

Toronto Notes 2023 – ELOM, “Professionalism and Interprofessional Communication”:

“When concerns arise about another provider’s care, direct communication is preferred before considering formal reporting. This maintains collaboration and fairness.”

MCCQE1 Objectives (ELOM > 90-2: Communication and Accountability):

“Candidates must demonstrate collegiality and appropriate methods for addressing concerns regarding another physician’s care.”

Empathizing (D) and validating blame is unprofessional. Reporting (B) is premature. Offering another provider (C) could undermine continuity. (E) is incorrect since the glucose should have been checked based on the presenting symptoms.

====================================================

Comprehensive and Detailed Explanation:

The patient presents with classic symptoms of schizophrenia: delusions, hallucinations, social withdrawal, and disorganized appearance. The first-line treatment is antipsychotic medication—risperidone is a well-tolerated option among second-generation antipsychotics.

Toronto Notes 2023 – Psychiatry, “Schizophrenia”:

“Schizophrenia is treated with second-generation antipsychotics such as risperidone. These reduce positive symptoms like delusions and hallucinations.”

MCCQE1 Objectives (Psychiatry > 71-3: Psychotic Disorders):

“Candidates must recognize and manage schizophrenia with antipsychotics and distinguish from other mood or personality disorders.”

CBT (E) is supportive but not first-line. ECT (A) is used for severe depression or catatonia. Valproic acid (C) and carbamazepine (D) are mood stabilizers, not first-line for schizophrenia.

Comprehensive and Detailed Explanation:

This patient has secondary amenorrhea, galactorrhea, and worsening headaches—suggestive of hyperprolactinemia, possibly due to a pituitary adenoma (prolactinoma). Visual field defects (typically bitemporal hemianopia) can result from optic chiasm compression.

Toronto Notes 2023 – Endocrinology / Reproductive Health:

“Prolactinomas may cause amenorrhea, galactorrhea, headaches, and visual field defects. Evaluate with serum prolactin and visual field testing.”

MCCQE1 Objectives (Endocrinology > 37-2: Pituitary Disorders):

“Candidates must recognize clinical signs of prolactinomas and know when to assess visual fields.”

Hirsutism (D) suggests androgen excess. Low BMI (B) can cause hypothalamic amenorrhea but wouldn’t explain galactorrhea. Nodular breast findings (A) are not related.

====================================================

The clinical picture is most consistent with acute pancreatitis (alcohol-related, epigastric pain radiating to back, vomiting, and ileus). CT abdomen with contrast is the best diagnostic tool if the diagnosis is uncertain or complications are suspected.

Toronto Notes 2023 – Gastroenterology, “Pancreatitis”:

“CT abdomen is indicated when diagnosis is unclear, symptoms are severe, or complications (e.g., necrosis, ileus) are suspected.”

MCCQE1 Objectives (Gastroenterology > 47-1: Acute Abdominal Pain):

“Candidates must investigate acute epigastric pain appropriately, especially in the context of alcohol use and systemic features.”

Ultrasound (B) is first-line for gallstones but not best here. Laparotomy (A) is not warranted without peritonitis or perforation. Endoscopy (D) is not indicated. Sengstaken-Blakemore (E) is for variceal bleeding, which is not suspected here.

====================================================

In a patient presenting with physical symptoms (e.g., hip pain) and prominent psychosocial red flags — loss of interest, decreased libido, and withdrawal — the next step is to screen for depression. Somatization is common in mood disorders.

Toronto Notes 2023 – Psychiatry, Depression:

“Patients with depression may present with somatic complaints. A thorough psychosocial assessment is essential in such cases, particularly when symptoms interfere with functioning.”

MCCQE1 Objectives – Psychiatry > Mood Disorders:

“Candidates must consider depression in patients with non-specific physical symptoms and reduced interest or motivation, particularly with social withdrawal.”

Imaging or physiotherapy may be needed later, but the most urgent and informative step is psychiatric screening.

====================================================
