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

Children with a first-degree relative who has premature coronary artery disease or hypercholesterolemia should undergo fasting lipid screening between ages 2–10. Since the child is 10, screening is indicated.

Toronto Notes 2023 – Pediatrics, “Preventive Care in Children”:

“Lipid screening is recommended for children ≥2 years old with a family history of early cardiovascular disease or hypercholesterolemia.”

MCCQE1 Objectives (Pediatrics > 78-1: Preventive Medicine):

“Candidates must screen children at high risk of cardiovascular disease appropriately, including lipid profile for familial hyperlipidemia.”

Diet and exercise counseling may follow screening, but testing is the first step. Reassurance alone (C) is inappropriate. Homocysteine (E) and HbA1c are not first-line tests in this setting.

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

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 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.

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

Comprehensive and Detailed Explanation:

Opioid-induced constipation is best managed with stimulant laxatives like senna or bisacodyl. Stool softeners such as docusate are insufficient as monotherapy. Senna stimulates peristalsis, making it more effective.

Toronto Notes 2023 – Palliative Care:

“Opioid-induced constipation requires stimulant laxatives such as senna. Stool softeners alone are not adequate.”

MCCQE1 Objectives (Palliative Care > 92-1: Symptom Management):

“Candidates must treat opioid-related side effects appropriately, including use of stimulant laxatives for constipation.”

Bulk agents (C) can worsen symptoms. Reducing morphine (D) may compromise pain control. Activity (E) helps but is insufficient as first-line management.
