anticoagulation.
2. A client with heart failure is receiving furosemide. Which finding requires
priority intervention?
A. Potassium 3.0 mEq/L
B. Weight loss of 1 kg in 24 hr
C. BP 110/70 mmHg
D. Urine output 2 L/day
Correct Answer: A
Rationale: Hypokalemia is a dangerous adverse effect of loop diuretics and can

4. Which task can be delegated to assistive personnel (AP)?
A. Teaching incentive spirometry
B. Assessing pain level
C. Feeding a stable client
D. Administering oral medications

8. Which finding indicates fluid volume overload?
A. Dry mucous membranes
B. Orthostatic hypotension
C. Bounding pulse
D. Decreased jugular venous pressure
Correct Answer: C
Rationale: Excess fluid causes bounding pulse and increased JVP.
9. Which vaccine is safe during pregnancy?
A. Varicella
B. MMR
C. Tdap
D. Live influenza nasal spray
, Correct Answer: C
Rationale: Tdap is recommended during pregnancy; live vaccines are

11. A nurse prepares to administer digoxin. Which finding requires withholding
the medication?
A. HR 58 bpm
B. K⁺ 4.0 mEq/L
C. BP 100/70 mmHg
D. RR 16/min
Correct Answer: A
Rationale: Digoxin should be held if apical pulse is 60 bpm.
12. A client with a new colostomy reports skin irritation around the stoma. The
nurse should recommend:
