SECTION A: MULTIPLE CHOICE QUESTIONS
1. A 68-year-old patient with heart failure is prescribed furosemide. Which
assessment finding requires immediate intervention?
A. Blood pressure 128/78 mmHg
B. Potassium level 3.0 mmol/L
C. Weight loss of 0.5 kg in 2 days
D. Urine output of 1500 mL/day
Correct Answer: B
Rationale:
Furosemide is a loop diuretic that causes potassium loss. Hypokalemia (K⁺ 3.0
mmol/L) can lead to life-threatening dysrhythmias and requires urgent correction.
2. A nurse is caring for a patient with increased intracranial pressure (ICP).
Which position is most appropriate?
A. Trendelenburg position

,Rationale:
Elevating the head at 30 degrees promotes venous drainage from the brain and
reduces ICP.

Rationale:
ST elevation is a hallmark of acute myocardial infarction.
8. A patient is prescribed warfarin. Which food should be limited?
