A PN is cаring fоr а client pоst-оperаtively who has been on bed rest for 48 hours. The nurse notices the client is complaining of shortness of breath(SOB), but the vital signs are stable, there is no fever, lung sounds are clear, and oxygen saturation is 96% on room air. The usual treatments have not alleviated the complaint. Which action demonstrates the nurse using critical thinking and cognitive skills to determine the most appropriate action?
