Question 1

A patient's chest X-ray shows cardiomegaly. Which serum laboratory finding is most consistent with compensated heart failure?

Accepted Answer

Elevated BNP (B-type natriuretic peptide)

Answer

BNP is released from ventricular myocytes in response to increased wall stress and volume overload, making it a key biomarker of heart failure.

Question 2

A fasting lipid panel shows triglycerides of 620 mg/dL. What is the most important immediate concern?

Accepted Answer

Risk of acute pancreatitis

Answer

Severe hypertriglyceridemia (>500 mg/dL) dramatically increases the risk of acute pancreatitis, which is the primary urgent concern.

Question 3

A point-of-care INR is 1.4 in a patient on warfarin for atrial fibrillation (target INR 2-3). What is the most appropriate action?

Accepted Answer

Increase the weekly warfarin dose and recheck in 1-2 weeks

Answer

An INR below the therapeutic range in a patient with AF indicates insufficient anticoagulation, requiring a dose increase and early follow-up.

Question 4

A patient with CKD stage 3 has a serum phosphorus of 5.8 mg/dL. What complication does this elevation most directly promote?

Accepted Answer

Secondary hyperparathyroidism and renal osteodystrophy

Answer

Hyperphosphatemia in CKD stimulates PTH secretion, leading to secondary hyperparathyroidism and subsequent renal osteodystrophy.

Question 5

A patient has a peak flow reading of 55% of personal best during an asthma visit. How should this be classified?

Accepted Answer

Red zone — medical alert, requires immediate intervention

Answer

A peak flow below 60% of personal best falls in the red zone, indicating severe airflow obstruction requiring immediate bronchodilator use and medical evaluation.
