A parent asks the nurse why the newborn is getting a vitamin K injection in the birth room.
The nurse explains that the injection is necessary because:
Newborns are prone to hypoglycemia, and vitamin K helps maintain a steady blood glucose level.
Vitamin K is needed for coagulation, and the newborn does not produce enough vitamin K.
The birthing parent was febrile at the time of birth and prophylactic vitamin K is necessary.
Newborns have deficient levels of prothrombin.
The Correct Answer is B
Choice A rationale
Vitamin K has no role in stabilizing blood glucose levels; hypoglycemia in newborns is managed differently.
Choice B rationale
Vitamin K is essential for blood clotting, and newborns typically have low stores at birth, necessitating supplementation to prevent bleeding disorders.
Choice C rationale
There is no established link between maternal fever and the need for vitamin K; prophylaxis is standard for all newborns regardless of maternal health.
Choice D rationale
Newborns do not have sufficient prothrombin or other clotting factors, which is why vitamin K administration is critical.

Correct Answer is B
Explanation
Choice A rationale
A front-facing car seat for an infant does not provide adequate protection in the event of a collision. Infants should always be in a rear-facing car seat to support their head, neck, and spine.
Choice B rationale
Using an infant model car seat designed specifically for the car ensures that the seat meets safety standards and is appropriate for the child's size and developmental needs, providing optimal protection.
Choice C rationale
Being able to fit a hand between the baby and the car seat harness indicates the harness is too loose. The harness should be snug enough that only one or two fingers can fit between the strap and the baby's chest to provide secure restraint.
Choice D rationale
A rear-facing car seat should not be placed in the front passenger seat due to the risk of injury from airbags. The safest position for a rear-facing car seat is in the back seat, away from active airbags.
