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:

A.

Newborns are prone to hypoglycemia, and vitamin K helps maintain a steady blood glucose level.

B.

Vitamin K is needed for coagulation, and the newborn does not produce enough vitamin K.

C.

The birthing parent was febrile at the time of birth and prophylactic vitamin K is necessary.

D.

Newborns have deficient levels of prothrombin.

Answer and Explanation

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.
