What step of the injection technique should the practical nurse (PN) reteach for a client self-administering subcutaneous insulin?

Reteaching the client to avoid selecting the same injection site that was used previously is crucial for managing insulin administration effectively. Using the same site repeatedly can lead to lipodystrophy, which are changes in fat tissue that can cause absorption issues and affect blood glucose control. By rotating injection sites, the client ensures better absorption of the medication and minimizes the risk of tissue damage.

Injections should be administered in different locations within the recommended subcutaneous areas, such as the abdomen or thighs, to promote effective insulin action and maintain skin integrity. This adjustment is essential for the client to achieve optimal control of their diabetes while minimizing potential complications associated with insulin therapy.

The other options, while relevant to injection technique, do not require reteaching in the same context. Injecting at a 45-degree angle is actually appropriate for certain types of subcutaneous injections, especially in clients with a smaller amount of subcutaneous fat. Wiping the injection site with alcohol is a standard practice to reduce the risk of infection. Pinching the skin can be beneficial for some individuals to help create a fold and ensure the medication is administered properly. Therefore, the emphasis on site rotation is paramount for maintaining client health and safety.
