A nurse is performing chest percussion on a client who has severe COPD. Which of the following actions should the nurse take?

A. Instructing the client to take shallow, rapid breaths is incorrect; deep breathing is encouraged to promote effective airway clearance. B. Placing a towel or thin cloth over the area to be percussed is appropriate to protect the skin and enhance client comfort during chest percussion. C. Percussing over each area for 10 minutes is excessive and could cause discomfort or injury; typically, 1 to 2 minutes per area is sufficient. D. Maintaining positioning for 45 minutes is unnecessary and could lead to discomfort or skin breakdown; position changes should occur more frequently.
