1. A patient with heart failure is receiving furosemide. Which electrolyte
imbalance should the nurse monitor for?
a) Hyperkalemia
b) Hypokalemia
c) Hypernatremia
d) Hypercalcemia
Furosemide is a loop diuretic that causes increased excretion of
potassium, leading to hypokalemia.
2. The nurse understands that which ABG result indicates metabolic acidosis?
a) pH 7.48, HCO₃ 28
b) pH 7.30, HCO₃ 18
c) pH 7.50, PaCO₂ 30
d) pH 7.45, PaCO₂ 40
Low pH and low bicarbonate levels indicate metabolic acidosis.
3. A postoperative patient is at risk for atelectasis. What is the best nursing
intervention?
, a) Restrict fluids
b) Encourage use of incentive spirometer
c) Keep patient flat
d) Limit ambulation
Incentive spirometry helps expand alveoli and prevents atelectasis.
4. Which dietary choice should the nurse recommend for a patient with
hypertension?
a) Canned soup
b) Fresh fruits and vegetables
c) Processed meats
d) Pickles
Fresh fruits and vegetables are low in sodium, which helps control BP.
5. Which symptom indicates right-sided heart failure?

systemic venous congestion.

first?
a) Call the provider immediately
b) Apply prescribed low-flow oxygen
c) Increase oxygen to 6 L/min
, d) Place the patient flat
Low-flow oxygen is used cautiously to maintain adequate oxygenation
without suppressing respiratory drive.
7. A nurse is caring for a patient with pneumonia. Which finding indicates
effective treatment?
a) Increased respiratory rate
b) Purulent sputum
c) Oxygen saturation 95% on room air
d) Adventitious lung sounds
Normal oxygen saturation indicates improved gas exchange and
resolution of pneumonia.
8. The nurse notes a potassium level of 2.8 mEq/L. What is the priority action?
a) Continue to monitor
b) Hold all potassium supplements
c) Notify the provider immediately
d) Encourage increased fluid intake
A low potassium level can cause dysrhythmias; the provider must be
notified for replacement orders.
9. A patient receiving IV morphine has a respiratory rate of 8/min. What
