After teaching a client with diabetes mellitus to inject insulin, the nurse assesses the client's understanding. Which statement made by the client indicates a need for additional teaching?

The lower abdomen is the best location because it is closest to the pancreas.

I can reach my thigh the best, so I will use the different areas of my thighs.

By rotating the sites in one area, my chance of having a reaction is decreased.

Changing injection sites from the thigh to the arm will change absorption rates.
