A nurse is preparing to administer an intramuscular (IM) injection to a client. What is the most appropriate site to use for an IM injection in an adult?

  • A. Dorsal gluteal muscle
  • B. Vastus lateralis muscle
  • C. Rectus femoris muscle
  • D. Deltoid muscle
Correct Answer: B

Rationale: The correct answer is B: Vastus lateralis muscle. The vastus lateralis muscle is a recommended site for IM injections in adults due to its size and accessibility. The dorsal gluteal muscle is not recommended for IM injections in adults due to the proximity to major nerves and blood vessels, increasing the risk of injury. The rectus femoris muscle is not a common site for IM injections in adults. The deltoid muscle is typically used for IM injections in small-volume medications or vaccines, especially in adults.
