Final answer:
The correct statement for preventing injury in a client with diabetes mellitus and peripheral numbness is "D. Examine your feet using a mirror every day." This daily foot examination is crucial for detecting potential injuries early on due to reduced sensation caused by diabetic neuropathy.
Step-by-step explanation:
The nurse would advise the client with diabetes mellitus experiencing peripheral numbness to: "D. Examine your feet using a mirror every day." This is crucial for individuals with diabetic neuropathy, as they may not be able to feel minor injuries due to reduced sensation, which can lead to serious infections. Daily inspection of the feet can help in the early detection of cuts, sores, or changes in the skin that may require medical attention. It is also important to maintain blood glucose control through monitoring and management strategies such as using a meter to monitor sugar levels and taking insulin injections when necessary.
Although other options, such as using a bath thermometer to test water temperature and rotating insulin injection sites, are also part of comprehensive diabetes management, they are not directly related to the specific issue of preventing injury due to reduced sensation in the feet.
