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.

Correct Answer is D
Explanation
Choice A rationale
The palpability of the posterior fontanel is not related to the position of the fetus.
Choice B rationale
The level of the ischial spines refers to the station of the fetus, not its position.
Choice C rationale
The passage of the largest fetal diameter through the pelvic outlet is a stage of labor, not a fetal position.
Choice D rationale
This is the correct answer. The left occiput posterior position refers to the position of the fetal head.
Correct Answer is D
Explanation
Choice A rationale
Fetal hyperinsulinemia is a condition where the fetus produces an excess amount of insulin, and it is more commonly associated with macrosomia (large for gestational age) rather than being small for gestational age.
Choice B rationale
Preterm delivery can result in a baby being small for birth weight, but it does not cause a baby to be small for gestational age. Small for gestational age means the baby’s weight is less than the 10th percentile for their gestational age.
Choice C rationale
Perinatal asphyxia, a lack of oxygen before, during, or just after birth, does not cause a baby to be small for gestational age. It can cause other complications, such as organ damage.
Choice D rationale
Placental inefficiency, where the placenta does not work as well as it should, can cause a baby to be small for gestational age. This is because the baby may not receive enough oxygen and nutrients from the mother.
