The nurse percusses a client with COPD and expects to hear:

A. Tympany is a high-pitched sound typically heard over a hollow organ such as the stomach. B. Hyperresonance is often heard in patients with COPD, as the lungs are hyperinflated, leading to an increased resonance when percussed. C. Resonance is normal and would be heard in healthy, air-filled lungs. D. Dullness would suggest a solid or fluid-filled area, which is not typical of COPD unless there is a complication like pleural effusion.
