Correct Answer: A

Rationale: The correct answer is A: Use the Z-track technique to administer the medication. This technique helps prevent leakage of the medication into surrounding tissues by sealing the medication in the muscle. The Z-track method involves pulling the skin laterally before injecting the medication, then releasing the skin after the injection. This creates a zig-zag path that closes after the needle is withdrawn, reducing the risk of irritation or staining at the injection site.
Choice B is incorrect because the needle size for IM injections in adults is typically 22-25 gauge and 1-1.5 inches long.
Choice C is incorrect as IM injections should be administered at least 2.5 cm (1 inch) away from the umbilicus.
Choice D is incorrect because aspiration (pulling back on the plunger to check for blood return) is not recommended for IM injections due to the risk of tissue trauma.
