Correct Answer is D

Explanation

A. Injecting insulin at a 90-degree angle is a common technique for subcutaneous insulin injections.

B. Rotating injection sites is important to prevent lipodystrophy and ensure proper absorption.

C. Insulin should be injected into areas with adipose tissue, such as the abdomen, thighs, or buttocks.

hypoglycemia. The current practice is to inject insulin subcutaneously without aspiration.
