A client with newly diagnosed type I diabetes asks why injection sites must be rotated. What is the best explanation?

• A. You may damage the tissues causing erratic absorption of insulin if you don't rotate sites.
• B. You may develop an infection if you use the same area too frequently.
• C. You may damage the superficial nerves in the skin and lose sensation if you use the same area too frequently.
• D. Your thighs will eventually become sore if you don't change injection sites.

Answer: (A)

Rotating injection sites helps prevent changes in subcutaneous tissue called lipodystrophy, which can make insulin absorption unpredictable. If injections are always given in the same spot, the tissue can develop lumps or thinning, altering how quickly insulin enters the bloodstream and leading to erratic blood glucose control. Using different sites or rotating within an area gives tissue time to heal and keeps absorption more consistent. While hygiene and technique matter for reducing infection, and nerve injury or soreness can occur in some cases, the primary reason for rotation is to avoid tissue changes that disrupt insulin absorption.
