Question 1 of 5
A nurse is preparing to administer vitamin K by IM injection to a newborn. The nurse should administer the medication into which muscle?
Correct Answer: C
Rationale: The correct answer is C: Vastus lateralis. This muscle is the preferred site for IM injections in infants due to its large muscle mass, well-developed structure, and minimal risk of injury to surrounding structures. Additionally, the vastus lateralis muscle is easily accessible and has fewer major blood vessels and nerves compared to other sites. Administering vitamin K in this muscle allows for optimal absorption and distribution of the medication. The other choices are incorrect because the gastrocnemius muscle (
A) is not commonly used for IM injections in newborns, the dorsogluteal site (
B) is not recommended due to potential injury to the sciatic nerve, and the ventrogluteal site (
D) may not be as well-developed in newborns as the vastus lateralis.
