A client asks the nurse why her newborn is getting an injection of vitamin K. The nurse’s most appropriate response is:
  1. “Vitamin K protects the newborn from nutritional deficiencies.”
  2. “Vitamin K protects the newborn from excessive bleeding.”
  3. “Vitamin K is needed to assist the maturation of the gut.”
  4. “Vitamin K prevents metabolic disorders.”
Explanation
Answer: B - Vitamin K is administered in the neonate to prevent excessive bleeding, in case of trauma. Vitamin K is synthesized by the bacteria in the large intestine. Because the neonates have immature large intestines, they are deficient in Vitamin K, which is needed to activate clotting factors II, VII, IX, and X.
