Section 1: Medical-Surgical Nursing (20 questions)
1. A nurse is caring for a client with heart failure who reports sudden onset of
dyspnea and coughing up pink, frothy sputum. Which action should the nurse
take first?
a) Administer furosemide IV push
b) Place the client in high Fowler’s position
c) Apply a non-rebreather mask at 100% oxygen
d) Morphine sulfate 2 mg IV
Correct Answer: b) Place the client in high Fowler’s position
Rationale: High Fowler’s position reduces venous return to the heart and
decreases pulmonary congestion. This is the priority before administering
medications or oxygen.
2. A client with chronic obstructive pulmonary disease (COPD) has an SpO2
of 88% on room air. Which supplemental oxygen delivery method is most
appropriate?
a) Non-rebreather mask at 15 L/min
b) Nasal cannula at 1-2 L/min
c) Simple face mask at 8 L/min
d) Venturi mask at 40% FiO2
Correct Answer: b) Nasal cannula at 1-2 L/min
Rationale: COPD clients rely on hypoxic drive; high oxygen can cause
hypercapnia. Low-flow oxygen via nasal cannula is safest.
, 3. A nurse is assessing a client 6 hours after a thyroidectomy. The client
reports tingling around the mouth and muscle twitching. Which laboratory
value should the nurse check immediately?
a) Serum calcium
b) Serum sodium
c) Serum potassium
d) Serum magnesium
Correct Answer: a) Serum calcium
Rationale: Tingling and twitching indicate hypocalcemia due to accidental
parathyroid removal during thyroidectomy.
4. Which ECG finding is most characteristic of hypokalemia?
a) Tall, peaked T waves
b) Prominent U wave
c) Wide QRS complex
d) ST segment elevation
Correct Answer: b) Prominent U wave
Rationale: Hypokalemia (low potassium) causes flattened T waves and a
prominent U wave.
5. A client with cirrhosis has ascites and is prescribed spironolactone. Which
finding indicates the medication is effective?
a) Increased abdominal girth
b) Weight loss of 2 kg in 3 days
c) Serum potassium of 3.2 mEq/L
d) Crackles in lung bases
Correct Answer: b) Weight loss of 2 kg in 3 days
Rationale: Spironolactone is a potassium-sparing diuretic; weight loss indicates
reduction of ascitic fluid.
