MCCQE Exam Dumps - Medical Council of Canada MCCQE Part 1 Questions and Answers

This elderly resident presents with symptoms suggestive of influenza or another respiratory viral illness shortly after admission to a long-term care (LTC) facility. MCCQE population health objectives emphasize early outbreak prevention in institutional settings. The first and most immediate step when a potentially contagious illness is identified is to isolate the symptomatic individual using appropriate droplet and contact precautions.

Prompt isolation reduces the risk of transmission to other vulnerable LTC residents, who are at high risk of severe complications. Additional steps—such as notifying public health authorities or closing the facility—are considered if an outbreak is confirmed or multiple cases occur. At this stage, there is only a single symptomatic patient.

Immunization during an acute febrile illness is not appropriate and would not provide immediate protection. Therefore, immediate isolation while arranging diagnostic testing and monitoring for additional cases is the correct infection prevention and control measure.

This patient has classic acute pericarditis : pleuritic chest pain relieved by sitting forward, a pericardial friction rub, diffuse ST-segment elevation with PR depression on ECG, and a small pericardial effusion on echocardiogram. MCCQE objectives emphasize recognizing the characteristic clinical and ECG features that distinguish pericarditis from myocardial infarction (diffuse ST elevation rather than territorial changes).

First-line treatment for uncomplicated acute pericarditis is high-dose nonsteroidal anti-inflammatory therapy , such as acetylsalicylic acid (ASA) or ibuprofen, often combined with colchicine to reduce recurrence risk. ASA is particularly appropriate when ischemia is in the differential diagnosis.

Apixaban (anticoagulation) is not indicated and may worsen effusion. Pericardiocentesis is reserved for large effusions or cardiac tamponade. Levofloxacin is unnecessary without evidence of bacterial infection. Beta-blockers such as metoprolol do not treat pericardial inflammation.

Thus, high-dose acetylsalicylic acid is the most appropriate initial management for uncomplicated acute pericarditis.

The image shows classic features of “early childhood caries” (ECC), often called " baby bottle tooth decay.” This typically affects upper incisors first due to prolonged exposure to milk/formula or sugary drinks during sleep.

Toronto Notes 2023 – Pediatrics, “Dental Health” Section:

“ECC is most commonly caused by prolonged nighttime bottle feeding with milk or juice. It affects upper anterior teeth due to pooling and lack of protective salivary flow.”

MCCQE1 Objectives (Pediatrics > 78-2: Preventive Care):

“Candidates must recognize risk factors for dental caries in young children, including nighttime bottle use and sugary liquid exposure.”

Antibiotics (C) or iron (D) can stain but do not cause this pattern of decay. Vitamin D (A) causes enamel hypoplasia or delayed eruption. Fluoride deficiency (B) causes diffuse decay, not selective anterior tooth loss.

Accurate dating is critical in pregnancies at high risk for preeclampsia and intrauterine growth restriction. First-trimester ultrasound is used to establish gestational age, which guides monitoring and interventions.

Toronto Notes 2023 – Obstetrics, High-Risk Pregnancy:

“In women with a history of preeclampsia, early and accurate dating allows for appropriate fetal surveillance and timely delivery.”

MCCQE1 Objectives – Obstetrics > Prenatal Care:

“Candidates should recognize the importance of accurate pregnancy dating in high-risk pregnancies.”

Prophylactic labetalol (E) is not indicated in normotensive patients. Genetic testing (A, B) is not appropriate unless additional risk factors are present. Bed rest (D) is not evidence-based for preeclampsia prevention.

This infant was born late preterm (36 weeks) with asymmetric intrauterine growth restriction (IUGR) and remains at the 3rd percentile. Although he is breastfeeding well, infants with IUGR and late prematurity often require enhanced caloric intake to support catch-up growth. MCCQE objectives emphasize optimizing postnatal nutrition in growth-restricted infants to promote appropriate weight gain while monitoring growth velocity.

Caloric fortification of expressed breast milk (or use of higher-calorie formula if needed) increases energy density without increasing feeding volume, supporting growth in infants who are small for gestational age. Simply continuing standard feeds may not provide sufficient calories for catch-up growth.

High-dose vitamin D is not indicated; routine supplementation (400 IU daily) is appropriate for breastfed infants. Early introduction of solids is not recommended before about 6 months of age. Switching to hydrolyzed formula is unnecessary without evidence of milk protein allergy.

Therefore, caloric-fortified feeding is the most appropriate next step to promote optimal growth in this infant.

This patient is currently non-communicative and therefore likely lacks decision-making capacity. MCCQE ethics objectives emphasize that when a patient’s prior capable wishes are clearly known, clinicians must follow those expressed values and directives. He previously stated he did not want life-prolonging measures; escalation (hospital transfer) and potentially curative treatment aimed primarily at prolonging life would conflict with that directive. The immediate best step is to provide comfort-focused care, addressing symptoms such as fever and distress with antipyretics and other palliative measures.

Calling family to “consider antibiotics” risks substituting others’ preferences for the patient’s known wishes; substitute decision makers are meant to apply the patient’s prior expressed wishes, not override them. Starting antibiotics while waiting to contact family similarly risks initiating life-prolonging therapy inconsistent with the directive. Catheter change may be clinically useful in catheter-associated infection, but the question frames a clear limit on life-prolonging interventions; symptom relief is the priority. Ongoing care should include reassessment of comfort, clear documentation of goals of care, and communication with family about the patient’s previously stated wishes and the plan for palliative management.

In girls with developmental disabilities, menstrual management should follow the same ethical and clinical principles as for other adolescents, emphasizing least invasive, reversible options and respect for future autonomy. Menstrual suppression may be appropriate to assist with hygiene and quality of life; however, hormonal methods are generally initiated after the onset of menarche to confirm pubertal development and exclude underlying endocrine disorders. Therefore, extended progestin-only therapy (e.g., depot medroxyprogesterone acetate) should not be started before menses begin. Hysterectomy is inappropriate as first-line management due to its irreversible nature, surgical risks, and significant ethical concerns regarding sterilization. Continuous combined oral contraceptives are not contraindicated and are commonly used for therapeutic amenorrhea. Evidence does not show consistent worsening of behavioural symptoms with appropriate hormonal suppression. Girls with developmental disabilities typically experience normal pubertal progression. MCCQE objectives emphasize patient-centered care, least restrictive interventions, ethical considerations in consent and capacity, and appropriate menstrual management strategies in adolescents with special needs.

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.

The symptoms described — haloes at night, monocular diplopia, and improved near vision (second sight) — are classic signs of nuclear sclerosis-type cataracts. On exam, the most consistent finding would be an altered red reflex due to lens opacification.

Toronto Notes 2023 – Ophthalmology, Cataracts:

“Cataracts can cause glare, monocular diplopia, and improved near vision. A diminished or irregular red reflex is commonly seen on direct ophthalmoscopy.”

MCCQE1 Objectives – Internal Medicine > Ophthalmologic Disorders:

“The candidate must recognize symptoms and physical findings of cataracts, including changes in red reflex and visual acuity.”

Options A and B are associated with lipid deposition and Wilson’s disease, respectively. Retinal exudates (D) suggest diabetic or hypertensive retinopathy. Increased intraocular pressure (E) suggests glaucoma but is not supported by this clinical picture.

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

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.
