MCCQE Leak Questions

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.
