A client undergoes an above-the-knee amputation (AKA) of the right leg because of peripheral vascular disease. On the second postoperative day, the nurse enters the room to take the client's vital signs and finds the client lying in a prone position. The client asks for assistance in turning. Which action should the nurse take first?

A. Determine how long the client has been lying prone: Prone positioning is used post-amputation to prevent hip flexion contractures. However, prolonged periods in this position can cause discomfort or complications. Knowing the duration helps evaluate if it’s appropriate to reposition or maintain it for therapeutic reasons. B. Measure the client's vital signs: Vital signs are important in the postoperative period, but this task can be completed after addressing the client’s immediate request and assessing the potential impact of their current positioning on healing and comfort. C. Inspect the dressing on the stump: Inspecting the stump is crucial for monitoring for infection or bleeding. However, unless there is a concern based on symptoms or reports from the client, it should follow assessment of position and comfort needs. D. Assist the client in turning to a position of comfort: Turning the client without assessing how long they have been prone could interfere with therapeutic positioning aimed at preventing complications like hip contractures, especially in early postoperative care.
