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.
