Correct Answer is D

Explanation

D. A 90° angle (perpendicular to the skin surface) is typically used for IM injections into muscles where the needle needs to penetrate deeply into the muscle tissue.

A. 60° angle is commonly used for IM injections in the deltoid muscle or thigh. However, it may not be optimal for the ventrogluteal site, which typically requires a different approach due to its deeper location and muscle structure.

B. A 45° angle is typically used for subcutaneous injections, where the needle is inserted into the fatty layer just below the skin surface.

C. This angle is steeper than 60° and is sometimes used for IM injections into muscles with thicker tissue or larger muscle mass.
