& C | 540 Original Practice Questions with Answers &
Rationales | NGN Case Scenarios
,VATI PN Comprehensive Predictor — Form A
1. A practical nurse is caring for a client who has pneumonia and a
temperature of 39.2°C (102.6°F). Which finding requires immediate
intervention?
A. Productive cough
B. Respiratory rate of 28/min
C. Oxygen saturation of 89%
D. Temperature of 39.2°C
Answer: _C. Oxygen saturation of 89%_
Rationale: An oxygen saturation of 89% indicates hypoxemia and requires prompt
intervention. The other findings are concerning but are less immediately life-
threatening.
2. A nurse is assessing a client with heart failure. Which finding indicates
worsening fluid retention?
A. Weight loss of 1 kg
B. Bilateral crackles
C. Heart rate of 72/min
D. Urine output of 1,500 mL/day
Answer: _B. Bilateral crackles**_
,Rationale: Crackles can indicate pulmonary fluid accumulation associated with
worsening heart failure.
3. A client receiving furosemide should be monitored for which electrolyte
imbalance?
A. Hypercalcemia
B. Hyperkalemia
C. Hypokalemia
D. Hypermagnesemia
Answer: _C. Hypokalemia**_
Rationale: Furosemide is a loop diuretic that increases urinary potassium excretion
and can cause hypokalemia.
4. A nurse is reinforcing teaching for a client taking warfarin. Which statement

A. “I should avoid all foods containing vitamin K.”
B. “I should keep my intake of vitamin K-containing foods consistent.”
C. “I can take aspirin whenever I have a headache.”
D. “I don't need blood tests while taking this medication.”
Answer: _B. “I should keep my intake of vitamin K-containing foods
consistent.”**_
Rationale: Vitamin K intake should remain relatively consistent because significant
changes can alter warfarin effectiveness.

the nurse do first?
A. Administer regular insulin.
B. Check the client's blood glucose.
C. Encourage the client to exercise.

potassium-wasting diuretic?
A. White rice
B. Banana
C. Applesauce
D. White bread
Answer: _B. Banana**_
Rationale: Bananas are rich in potassium and can help increase dietary potassium
intake.
7. A client with chronic obstructive pulmonary disease is receiving oxygen.
Which prescription should the nurse question?
A. Oxygen at 2 L/min via nasal cannula
B. Encourage pursed-lip breathing
