Question 1

A patient in the PACU is showing signs of laryngospasm after extubation. Which is the priority nursing intervention?

Accepted Answer

Apply positive pressure ventilation with a bag-valve mask

Answer

Positive pressure ventilation with a bag-valve mask is the first intervention to break laryngospasm and maintain oxygenation.

Question 2

Which of the following is the MOST reliable indicator of adequate reversal of neuromuscular blockade in the PACU?

Accepted Answer

Ability to sustain head lift for 5 seconds

Answer

A 5-second head lift demonstrates adequate neuromuscular recovery and respiratory muscle strength needed for safe extubation.

Question 3

A patient returns from surgery with a Jackson-Pratt drain. The nurse notes the bulb is firm and not compressed. What action should be taken?

Accepted Answer

Empty the drain and recompress the bulb to restore suction

Answer

A Jackson-Pratt drain works by closed suction; the bulb must be emptied and recompressed to maintain negative pressure and effective drainage.

Question 4

In caring for a patient who underwent general anesthesia, the nurse assesses for which early sign of malignant hyperthermia?

Accepted Answer

Muscle rigidity and rapid rise in end-tidal CO2

Answer

Muscle rigidity and a rapid increase in end-tidal CO2 are early hallmarks of malignant hyperthermia due to uncontrolled skeletal muscle hypermetabolism.

Question 5

A patient is NPO for surgery and asks why they cannot drink clear liquids the morning of their procedure. The best nurse's response is:

Accepted Answer

Even clear liquids increase the risk of aspiration during anesthesia

Answer

Clear liquids in the stomach increase aspiration risk during anesthesia induction when protective airway reflexes are suppressed.
