A nurse is preparing to administer phytonadione (Vitamin K) to a newborn shortly after birth. The newborn's parent asks why this injection is necessary since the baby appears healthy. Which explanation by the nurse best describes the reason for this medication?
- Vitamin K is given to prevent jaundice by supporting bilirubin metabolism in the liver.
- Newborns have low clotting factor levels because intestinal flora that synthesize Vitamin K are not yet established, increasing bleeding risk.
- Newborns cannot absorb fat-soluble vitamins from breast milk, so supplementation is always required.
- Newborns are born with immature immune systems and need Vitamin K to fight infections.
