Correct Answer is C

Explanation

Choice A rationale:

An angle of 60° is not typically used for IM injections. It is more commonly used for subcutaneous injections.

Choice B rationale:

An angle of 45° is also more commonly used for subcutaneous injections, not IM injections.

Choice C rationale:

An angle of 90° is the correct angle for an IM injection into the ventrogluteal muscle. This allows for the needle to penetrate deep into the muscle tissue.

Choice D rationale:

An angle of 75° is not typically used for any type of injection. It could potentially cause injury to the client if used for an IM injection.
