Medical Council of Canada Updated MCCQE Exam Questions and Answers by emile

According to Canadian medical ethics and legal standards, physicians mustcommunicate diagnosis and treatment options directly to the patient, unless the patient hasexplicitly waived their right to knowordelegated decision-making authority. The patient's autonomy is paramount.

Toronto Notes 2023 – Ethical, Legal, and Organizational Medicine, "Truth-Telling" Section:

“Physicians are obligated to disclose relevant health information to patients unless the patient has clearly indicated a desire not to be informed. Family members do not have the authority to request that information be withheld from a competent adult.”

MCCQE1 Objectives (ELOM > Ethical Issues > Medical Ethics):

“The candidate must be able to apply the principles of patient autonomy… This includes full disclosure of diagnosis, prognosis, and treatment options unless waived by the patient.”

Booking an immediate appointment (C) allows you to assess her decision-making capacity and proceed with informed discussion. The other options either bypass the patient (A, B, E) or provide misleading/incomplete information (A, D), which violates ethical and legal obligations.

The image shows an asymmetrical light reflex (corneal light reflex not centered in both eyes), which is diagnostic of strabismus. This misalignment of the eyes must be treated early to prevent amblyopia (lazy eye).

Toronto Notes 2023 – Pediatrics, Ophthalmology:

“Strabismus presents with misaligned visual axes. The Hirschberg light reflex is off-center in the affected eye. Prompt referral is necessary to prevent amblyopia.”

MCCQE1 Objectives – Pediatrics > Vision and Developmental Disorders:

“Candidates must recognize strabismus on visual screening and refer early for correction to prevent permanent vision impairment.”

Pseudostrabismus (B) can be ruled out here because the light reflex is not symmetric. Ptosis (A) involves drooping of the eyelid, which is not evident. Cataracts (D) would typically present with a leukocoria (white reflex), not misalignment.

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

Clozapine and quetiapine are associated with significant weight gain and increased risk of type 2 diabetes. With a BMI of 32 and weight gain over the past year, screening for diabetes is appropriate and evidence-based.

Toronto Notes 2023 – Endocrinology, Diabetes & Psychiatry Sections:

“Second-generation antipsychotics such as clozapine increase the risk of metabolic syndrome and type 2 diabetes. Regular screening is recommended for patients with these risk factors.”

MCCQE1 Objectives – Internal Medicine > Endocrinology:

“Candidates should screen high-risk individuals, especially those on antipsychotics with weight gain, for diabetes using fasting glucose or HbA1c.”

While sleep apnea (C) is also possible, diabetes screening is the most appropriate and urgent next step in this patient. COPD (A) would present with respiratory symptoms. Cushing’s (B) and acromegaly (E) are less common and have other distinct features.

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

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.
