A nurse is preparing to administer vitamin
K. Which of the following muscles should the nurse consider for the injection?
Deltoid
Vastus lateralis
Ventrogluteal
Dorsogluteal .
The Correct Answer is B
Choice A rationale
The deltoid muscle is not typically used for intramuscular injections in infants due to its small size.
Choice B rationale
The vastus lateralis muscle is one of the preferred sites for intramuscular injections in infants, including the vitamin K injection. This muscle is large enough to absorb the medication, and injections here carry less risk of hitting a nerve or blood vessel.
Choice C rationale
The ventrogluteal muscle is not typically used for intramuscular injections in infants. This site is often used in older children and adults.
Choice D rationale
The dorsogluteal site is not recommended for intramuscular injections due to the risk of damaging the sciatic nerve.
