Correct Answer: C - Cystitis
Expert Rationale:
This is a classic presentation of an uncomplicated lower urinary tract infection / acute cystitis.
The triad of dysuria, urinary urgency, and frequency with suprapubic tenderness indicates
bladder inflammation. The key negative findings rule out upper UTI: No fever, no flank pain, and
no costovertebral angle tenderness [CVA tenderness] mean the kidneys are not involved.
• Why Pyelonephritis is wrong: Pyelonephritis is an upper UTI/infection of the kidney
parenchyma. It would present with systemic symptoms: fever, chills, nausea/vomiting,
flank pain, and positive CVA tenderness on exam.
• Why Renal calculi is wrong: Renal stones present with severe, colicky flank pain
radiating to the groin, hematuria, nausea/vomiting, and restlessness. Not isolated
irritative voiding symptoms.
, • Why Urethral stricture is wrong: Stricture presents with obstructive symptoms -
decreased urinary stream, hesitancy, incomplete emptying, and straining, not acute
irritative symptoms and suprapubic tenderness.
Correct Answer: D - Atherosclerosis resulting in coronary artery narrowing
Expert Rationale:
The primary pathophysiology of CAD in the presence of metabolic risk factors is atherosclerosis.
Hypertension, hyperlipidemia, and diabetes all cause chronic endothelial injury and
inflammation. LDL cholesterol deposits in the subendothelial space, oxidizes, attracts
macrophages that become foam cells, forming a fatty streak and then a fibrous plaque. This
plaque progressively narrows the coronary lumen, reducing myocardial blood flow and causing
ischemia, especially on exertion.
• Why C is not the best answer: Impaired dilation due to endothelial dysfunction is an
early step in atherosclerosis and contributes, but the primary structural cause of chronic
CAD is the atherosclerotic plaque itself. Endothelial dysfunction alone does not explain
the narrowing.
