Medical Council of Canada MCCQE Dumps Questions Answers

The most likely diagnosis is acute anterior uveitis (iritis). The key MCCQE clinical pattern is painful red eye with ciliary flush (injection worst adjacent to the iris/limbus) and marked photophobia, especially consensual photophobia, which strongly points to inflammation of the iris and ciliary body. The sluggish light response and miosis (smaller pupil) are also typical of iritis due to sphincter spasm and inflammation. Intraocular pressure is normal, helping to rule out acute angle-closure glaucoma, which usually presents with elevated IOP, corneal haze, and a mid-dilated fixed pupil. Optic neuritis classically causes decreased color vision and pain with eye movement rather than ciliary flush. Viral conjunctivitis causes diffuse conjunctival injection and irritation/grittiness, not severe pain with consensual photophobia. Scleritis causes deep “boring” pain and violaceous scleral hue, not miosis/consensual photophobia as dominant features. Difficulty visualizing the fundus can occur with significant miosis.

Fibrocystic change is the most common benign breast condition in women of reproductive age. It typically presents with diffuse nodularity or " lumpy " areas, especially in the upper outer quadrant, and varies with the menstrual cycle. No dominant mass or systemic signs are expected.

Toronto Notes 2023 – Gynecology, “Benign Breast Conditions”:

“Fibrocystic changes often present with bilateral or unilateral nodularity, most commonly in the upper outer quadrants, without discrete masses.”

MCCQE1 Objectives (Gynecology > 81-1: Breast Conditions):

“Candidates must differentiate benign breast conditions from malignant ones based on presentation and physical exam findings.”

Paget disease (B) presents with nipple changes. Intraductal carcinoma (C) typically shows a discrete mass or suspicious features. Phyllodes tumours are usually well-circumscribed. Mastitis (E) is inflammatory and associated with erythema, fever, and tenderness.

This patient has life-threatening complications of missed dialysis , including severe hyperkalemia (K⁺ 7.1 mmol/L), metabolic acidosis (HCO₃⁻ 11 mmol/L), volume overload with pulmonary edema (hypoxia, crackles, elevated JVP), and altered mental status. MCCQE objectives emphasize immediate recognition and treatment of emergent indications for dialysis (AEIOU: Acidosis, Electrolyte abnormalities, Intoxication, Overload, Uremia) . This patient meets multiple criteria—particularly refractory hyperkalemia and pulmonary edema—requiring urgent hemodialysis .

In emergencies where delay would risk death or serious harm, treatment proceeds under implied consent , even if the patient is confused and capacity is uncertain. Contacting family or psychiatry would dangerously delay life-saving care. While temporizing measures (e.g., IV calcium, insulin/glucose) may be given, definitive management is emergent dialysis. Morphine and furosemide alone are inadequate in severe renal failure with life-threatening hyperkalemia. Therefore, immediate initiation of urgent dialysis is the correct next step.
