Following admission, a client with a vascular occlusion of the right lower extremity calls the nurse and reports difficulty sleeping because of cold feet. Which of the following nursing actions should the nurse take to promote the client's comfort?

A. Providing slipper socks is a safe and appropriate intervention to help keep the feet warm and promote comfort without causing injury. B. Heating pads are contraindicated for clients with decreased circulation because they may not perceive the heat adequately, increasing the risk for burns. C. Rubbing the feet briskly can cause tissue injury in clients with impaired perfusion due to fragile skin and poor circulation. D. Increasing oral fluid intake does not directly address the client’s complaint of cold feet and is not an immediate comfort measure.
