The nurse percusses a client's lung and hears a dull sound throughout the left lung. What does the nurse suspect based on this assessment finding?
1. Emphysema
2. Pneumothorax
3. Pneumonia
4. Hyperinflation of the lung
Correct Answer: 2
A lung that is air-filled would normally return a resonant sound, so the dull sound would lead the nurse to suspect a collapsed lung or pneumothorax. Emphysema and hyperinflation would produce a resonant sound. Pneumonia might return a dull sound over the fluid-filled area, but the remainder of the lung would be resonant.
