A nurse is caring for a client who had abdominal surgery. The client is grimacing and has a respiratory rate of 24/min. Which of the following actions should the nurse take first?

A. Offer the client a cold compress: While a cold compress might help with swelling or discomfort, it is more important to assess the client's pain level first to understand the cause of the grimacing. B. Play music in the client's room as a distraction: This could help later, but pain needs to be addressed first. C. Check the client's current level of pain: Grimacing could indicate pain, which should be evaluated and addressed first to provide comfort and prevent complications like increased stress or decreased respiratory effort. D. Assist the client to reposition in bed: Repositioning could help alleviate discomfort, but pain should be assessed first to ensure the client is not in severe pain.
