A healthcare professional is supervising a newly licensed colleague who is preparing to administer an intramuscular injection. Which of the following actions by the newly licensed colleague requires intervention?

  • A. Selecting a 25-gauge needle
  • B. Administering the injection at a 45° angle
  • C. Using the ventrogluteal site for the injection
  • D. Aspirating for blood return before injecting the medication
Correct Answer: B

Rationale: The correct answer is B. Administering an intramuscular injection at a 90° angle is essential for proper medication delivery into the muscle tissue. Injecting at a 45° angle is incorrect for intramuscular injections and is typically used for subcutaneous injections where the needle is inserted into the fatty tissue layer beneath the skin. Choice A is correct as selecting a 25-gauge needle is appropriate for an intramuscular injection. Choice C is also correct as the ventrogluteal site is a suitable site for intramuscular injections. Choice D is correct as aspirating for blood return is a necessary step to ensure the needle is not in a blood vessel before injecting the medication.
