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

This adolescent exhibited acute suicidal behavior (attempted to jump out of a window), which is a psychiatric emergency. Regardless of intoxication or cause, such behavior mandates a safety-first approach: involuntary psychiatric assessment and protection from self-harm.

Toronto Notes 2023 – Psychiatry, “Suicide and Crisis Intervention” Section:

“Involuntary psychiatric admission is indicated when a patient poses a danger to themselves or others. Suicidal ideation or attempts require immediate evaluation and monitoring.”

MCCQE1 Objectives (Psychiatry > 79-2: Suicide and Risk Management):

“Candidates must identify suicidal behavior and initiate appropriate action, including involuntary admission if necessary for safety.”

Observation (B) may miss the window for action. Parents (A) should be contacted but are not a substitute for admission. Chlordiazepoxide (C) is not first-line in this scenario.

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

Endocervical polyps are common and often benign. An ulcerated polyp may bleed but is not itself suspicious unless it shows atypical features. The appropriate management is to remove the polyp (polypectomy) and send it for histopathology to exclude malignancy.

Toronto Notes 2023 – Gynecology, Cervical Pathology:

“Endocervical polyps are removed by polypectomy and sent for histological analysis. Most are benign. Atypical or ulcerated appearance may raise concern, but biopsy is unnecessary if the entire lesion is excised.”

MCCQE1 Objectives – Gynecology > Abnormal Bleeding and Cervical Lesions:

“Candidates should recognize that cervical polyps causing intermenstrual bleeding should be removed and assessed histologically.”

Colposcopy (B) is reserved for abnormal cytology or high-risk lesions. Cryotherapy (A) is for cervical dysplasia. Punch biopsy (E) is used for lesions that are not amenable to polypectomy.

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

Comprehensive and Detailed Explanation:

Physicians must avoid conflicts of interest and maintain professional boundaries with patients and their families. Accepting a personal financial gift, regardless of intent, is inappropriate and unethical.

Toronto Notes 2023 – Ethics and Professionalism:

“Personal gifts of significant value from patients or families should be declined to avoid real or perceived conflicts of interest.”

MCCQE1 Objectives (ELOM > 90-3: Professionalism and Boundaries):

“Candidates must maintain ethical boundaries and refuse financial incentives that could compromise or appear to compromise clinical judgment.”

Other options (A, B, E) still involve a conflict. D is helpful, but the ethical obligation is to decline the cheque directly.

The presentation is consistent with cervical spondylosis — a degenerative condition. In the absence of neurologic findings, further imaging beyond plain radiography is not warranted. Management includes conservative measures such as physiotherapy and analgesia.

Toronto Notes 2023 – Rheumatology, Cervical Spondylosis:

“Patients with typical cervical spondylosis and no red flags (e.g., neurologic deficits) do not require MRI. Treatment is conservative. Radiographs showing disc space narrowing and osteophytes confirm diagnosis.”

MCCQE1 Objectives – Internal Medicine > Musculoskeletal Disorders:

“Candidates must recognize typical degenerative spine disorders and avoid unnecessary investigations when clinical findings are straightforward.”

MRI (B) is useful if myelopathy or radiculopathy is suspected. CT (A), EMG (C), and LP (D) are not indicated here.

Comprehensive and Detailed Explanation:

Transient synovitis is the most common cause of hip pain and limp in children aged 3–10 years. It is often preceded by a viral infection. Patients appear well, can often bear weight, and have only mild to moderate elevation in inflammatory markers. Radiographs are normal.

Toronto Notes 2023 – Pediatrics, “Limping Child”:

“Transient synovitis is benign and self-limiting. Presentation includes mild limp, low-grade fever, normal or slightly elevated CRP/ESR, and ability to bear weight.”

MCCQE1 Objectives (Pediatrics > 78-2: Musculoskeletal Disorders):

“Candidates must distinguish between transient synovitis and more serious causes of limping, such as septic arthritis.”

Septic arthritis (A) usually causes inability to bear weight and more significant fever and CRP elevation. Osteomyelitis (B) typically presents with localized tenderness and systemic signs. Bursitis (D) is rare in young children. JIA (E) is chronic.

For pregnant patients with opioid use disorder, opioid agonist therapy with methadone or buprenorphine is the standard of care. Detoxification is not recommended in pregnancy due to increased risk of fetal distress, preterm labor, and relapse. Methadone reduces illicit opioid use and stabilizes both mother and fetus.

Toronto Notes 2023 – Addiction Medicine / Obstetrics:

“Methadone maintenance therapy is the treatment of choice for pregnant patients with opioid use disorder. Detoxification is not advised during pregnancy due to relapse risk and potential harm to the fetus.”

MCCQE1 Objectives (Obstetrics > 80-3: Substance Use in Pregnancy):

“Candidates must manage opioid use disorder in pregnancy with evidence-based therapies, including referral for methadone or buprenorphine.”

Counselling alone (D) is insufficient as first-line therapy. Home detox (C) is unsafe. Inpatient detox (A) is not recommended in pregnancy.

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

In cross-cultural care, especially for recent immigrants, it is essential to build rapport and respect patient preferences regarding family involvement. Involving family in the interview respects cultural norms and improves trust. A trained interpreter should be used to maintain confidentiality and accuracy, but collaboration with the family initially may encourage later private disclosure.

Toronto Notes 2023 – Ethics and Communication, “Cultural Competence”:

“When encountering language or cultural barriers, patient comfort and cultural context must be respected. Interviewing the patient and family together may facilitate trust, after which individual conversations may be possible.”

MCCQE1 Objectives (ELOM > 90-1: Communication and Patient-Centered Care):

“Candidates must approach patients in a culturally sensitive manner, particularly recent immigrants or those with language barriers, and foster trust.”

Insisting on a private interview (A) may alienate the patient. Family members should not act as interpreters (C). Written accounts (D) are inefficient and impersonal in acute mental health settings.

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

Visible rectal bleeding, even in the absence of systemic symptoms, warrants diagnostic colonoscopy to rule out colorectal cancer, polyps, or IBD—especially in adults over 40. FIT is for asymptomatic screening only.

Toronto Notes 2023 – Gastroenterology, “Approach to Lower GI Bleeding”:

“In patients with overt rectal bleeding, colonoscopy is the investigation of choice regardless of age or FIT status.”

MCCQE1 Objectives (Internal Medicine > Gastroenterology > 47-1):

“Candidates must evaluate rectal bleeding with colonoscopy, even in the presence of minor findings on physical exam (e.g., skin tag).”

FIT (A) is not appropriate for symptomatic patients. CEA (D) is a tumor marker for surveillance, not diagnosis. CT colonography (C) is less sensitive for lesions than colonoscopy.

Comprehensive and Detailed Explanation:

At 20 weeks’ gestation, the uterine fundus typically reaches the umbilicus. If the fundal height is lower than expected at a stated gestational age of 26 weeks, the most likely explanation—especially with no prior care—is a dating error.

Toronto Notes 2023 – Obstetrics:

“Fundal height at the umbilicus corresponds to ~20 weeks. In women lacking early prenatal care, dating errors are common causes of fundal height discrepancy.”

MCCQE1 Objectives (Obstetrics > 80-3: Routine Antenatal Care):

“Candidates must interpret fundal height and reconcile discrepancies with gestational age.”

IUGR and oligohydramnios are possible but require imaging confirmation. Bicornuate uterus may cause fundal shape anomalies but not significant dating discrepancy. A mole (D) would increase, not decrease, size.

Comprehensive and Detailed Explanation:

This patient presents with the classic triad of normal pressure hydrocephalus (NPH): gait disturbance (often wide-based and magnetic), cognitive decline, and urinary incontinence. The combination, especially with the gait being most prominent, is highly suggestive.

Toronto Notes 2023 – Geriatrics / Neurology:

“NPH presents with gait disturbance, dementia, and urinary incontinence. Gait is typically broad-based and magnetic. Imaging shows ventriculomegaly without elevated pressure.”

MCCQE1 Objectives (Geriatrics > 41-1: Cognitive Disorders):

“Candidates must identify NPH and distinguish it from other dementias based on clinical triad and gait features.”

Alzheimer’s (B) primarily presents with memory loss. Parkinson’s (A) has bradykinesia and rigidity. Lewy body dementia (C) includes visual hallucinations and fluctuating cognition. FTD (E) has personality and behavioral changes.
