While counting the respirations of an adult client who is bedfast, the nurse observes that the client uses the sternocleidomastoid, trapezius, and abdominal muscles during respirations. Which action should the nurse take in response to this finding?

A. Documenting asymmetrical thoracic movement: While this might be a finding, it's not the most urgent action. B. Assist the client to a position that helps the client breathe more easily. Sternocleidomastoid, trapezius, and abdominal muscle use: These muscles are accessory muscles that help with breathing when the diaphragm and intercostal muscles (primary muscles of respiration) are not functioning optimally. This use suggests laboured breathing. Priority action: The client's respiratory distress is the most pressing concern. C. Incentive spirometer: This device helps improve lung expansion but is not the first-line intervention in this situation where the client is already struggling to breathe. D. Encouraging deep breaths: This might further strain the respiratory muscles.
