A nurse is reinforcing teaching to a client who has a spinal cord injury about prevention of atelectasis. Which of the following statements should the nurse include in the teaching?

A. "Do panting breaths several times a day.": Panting breaths are shallow and do not adequately expand the alveoli. Shallow breathing increases the risk of atelectasis rather than preventing it. B. "Strengthen your chest muscles by performing therapy exercises.": Chest and respiratory muscle exercises help improve lung expansion and enhance the ability to cough effectively. Strengthening these muscles is essential for preventing atelectasis in clients with a spinal cord injury. C. "Perform deep coughing twice a day.": Deep coughing should be done more frequently than twice a day to effectively clear secretions and prevent alveolar collapse. Limiting it to twice daily is insufficient for atelectasis prevention. D. "Get plenty of rest throughout the day.": While rest is important for overall recovery, excessive rest and inactivity can contribute to shallow breathing and increase the risk of atelectasis. Active respiratory exercises are more critical for prevention.
