Pharmacological and Parenteral TherapiesQuestion 2072 of 2368

A parent asks why the newborn needs a vitamin K injection. What is the nurse's best response?

  1. It prevents a serious eye infection that can be acquired during the birth
  2. It replaces the minimal vitamin K stores newborns have, which are needed to form clots
  3. It protects the liver from hepatitis B infection during the first year of life
  4. It lowers the bilirubin level to prevent jaundice during the first week of life
Show answer

Correct answer: It replaces the minimal vitamin K stores newborns have, which are needed to form clots

Vitamin K helps blood clot, and a deficiency can cause bleeding that leads to brain damage or death.
