Q1. A nurse is caring for a patient with active tuberculosis. Which
interventions are necessary to prevent transmission? Select all that
apply.
A: Place the patient in a negative-pressure room
B: Wear an N95 respirator when entering the room
C: Keep the door to the patient’s room open for ventilation
D: Use standard precautions only
E: Instruct the patient to wear a surgical mask when leaving the
room
Answer: A, B, E
Explanation: A, B, and E are correct because negative pressure,
N95 respirator, and patient mask prevent airborne transmission.
C is incorrect (door must stay closed). D is incorrect (airborne
precautions required beyond standard).
, Q2. A patient is prescribed digoxin and furosemide. Which assessment
finding requires immediate nursing intervention?
A: Apical heart rate of 62 beats per minute
B: Serum potassium level of 3.2 mEq/L
C: Blood pressure of 130/78 mm Hg
D: Urinary output of 30 mL/hour
Answer: B
Explanation: Hypokalemia (K <3.5) increases the risk of digoxin
toxicity and life-threatening dysrhythmias. The other findings are
within normal limits.
Q3. A patient with chest tubes after thoracotomy has continuous
bubbling in the water-seal chamber. What is the priority action?
A: Clamp the chest tube immediately
B: Assess for an air leak
C: Increase suction pressure
D: Replace the drainage system
Answer: B
Explanation: Continuous bubbling indicates an air leak; the
priority is to locate the source. Clamping can cause tension
pneumothorax. Suction adjustment and replacement are not first
steps.
