MCCQE Exam Questions Tutorials

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.

A history of previous alcohol withdrawal seizures is the single greatest predictor of future withdrawal seizures. This establishes a sensitization response within the central nervous system.

Toronto Notes 2023 – Addiction Medicine:

“A prior history of alcohol withdrawal seizures is the most important risk factor for recurrent seizures during future withdrawal episodes.”

MCCQE1 Objectives (Internal Medicine > Substance Use > 58-3):

“Candidates must identify individuals at high risk for severe alcohol withdrawal based on past withdrawal history, including seizures and delirium tremens.”

Although quantity, duration, and comorbidities contribute to risk, a prior withdrawal seizure most strongly predicts recurrence.

By increasing the threshold required for a positive test result, the developers have made the test more stringent. This reduces false positives, thereby increasing specificity. However, increasing the cutoff also means that some individuals with lower (but still clinically significant) levels of proteinuria will now test negative. As a result, the number of false negatives increases and sensitivity decreases. This reflects the fundamental trade-off between sensitivity and specificity when adjusting a diagnostic threshold. Screening tests typically favor high sensitivity to minimize missed cases, particularly for serious but treatable conditions. Raising the threshold shifts the balance toward higher specificity at the expense of sensitivity. Positive predictive value (PPV) would likely increase because fewer false positives occur, but PPV also depends on disease prevalence. According to MCCQE objectives, candidates must understand how changes in diagnostic thresholds affect test characteristics, including sensitivity, specificity, predictive values, and false positive/false negative rates, and apply these principles appropriately in screening and clinical decision-making.

This patient presents with panic-like somatic symptoms triggered by bereavement. Normal investigations rule out cardiac pathology. Grief therapy is appropriate as the underlying stressor is unresolved grief and anxiety.

Toronto Notes 2023 – Psychiatry, Grief and Anxiety Disorders:

“Bereavement-related anxiety and somatization are common. Grief counseling can help reduce somatic and psychological symptoms when medical causes are ruled out.”

MCCQE1 Objectives – Psychiatry > Anxiety and Bereavement:

“Candidates should recognize psychological sequelae of grief, including panic and health anxiety, and provide appropriate psychological support.”

Metoprolol (C) is not indicated without confirmed cardiac cause. Lorazepam (B) may offer short-term relief but does not address the underlying grief. Stress testing (A) is unnecessary with repeated normal investigations.
