مريض يستخدم قلم الإنسولين. أي تعليم صحيح عن مكان الحقن؟

A client uses an insulin pen. Which teaching about injection sites is correct?

1. Inject into fatty lumps because they are painless
2. Inject into a visible vein for faster action
3. Inject into the same spot every day as it hurts less
4. Rotate sites within the same area to avoid fatty lumps

Answer: D) Rotate sites within the same area to avoid fatty lumps. Rotation prevents lipohypertrophy, which causes erratic absorption. The abdomen absorbs fastest, and the pen is held for 10 seconds after injecting.
