Clinical Medical Assistant Certification Exam Practice Question

Correct Answer: E

Rationale: Subcutaneous injection involves administering medication into the tissue layer between the skin and muscle, making it the appropriate choice for this question.

Intra-articular injections target joints directly, while intradermal injections are given within the dermis layer of the skin, which is too shallow. Intramuscular injections penetrate deeper into the muscle tissue, and intravenous injections deliver substances directly into the bloodstream, bypassing tissue layers altogether. Each of these methods serves specific purposes, but only subcutaneous injections are positioned just beneath the skin and above the muscle.
