Question 1 of 5
A client with pneumonia who has an emergent episode of respiratory distress is intubated and transferred to the intensive care unit. The client's chest x-ray shows consolidation in the left lobe, and physical assessment reveals diminished lung sounds. The nurse administers acetylcysteine as prescribed per nebulization via endotracheal tube. Which therapeutic response of this medication should the nurse expect?
Correct Answer: C
Rationale: Acetylcysteine, a mucolytic, breaks down mucus, increasing sputum production (
C) to clear airways. Bronchodilation (
A) is not its action. Unpleasant smell (
B) is a side effect, not therapeutic. Hypotension (
D) is a rare adverse effect.
