A nurse is preparing to administer vitamin K IM to a newborn. Into which of the following muscles should the nurse inject the medication?

A. The deltoid muscle is typically used for intramuscular injections in adults, but it is not the preferred site for newborns due to their small muscle mass. B. The vastus lateralis muscle, located on the lateral aspect of the thigh, is the preferred site for intramuscular injections in newborns and infants due to its large muscle mass and accessibility. C. While the ventrogluteal site is commonly used for intramuscular injections in adults, it may not be as easily accessible or preferred in newborns. D. The dorsogluteal site is not recommended for intramuscular injections in newborns due to the risk of injury to the sciatic nerve and other underlying structures.
