The nurse teaches new mothers about the reason their infants receive vitamin K. The nurse evaluates instruction as being effective when the mothers make which statement?

1. "Our babies do not need an injection of vitamin K unless bleeding is observed."
2. "Our babies will be able to get enough vitamin K through breast milk."
3. "Our babies do not have enough intestinal bacteria to synthesize vitamin K."
4. "Our babies could receive vitamin K through a liquid or an injection."


Correct Answer: 3
Rationale 1: Vitamin K injection must be used before bleeding is observed in the infant.
Rationale 2: Vitamin K is not present in high enough amounts in breast milk to protect the infant from bleeding.
Rationale 3: The infant's gut is sterile, so there is inadequate bacteria to synthesize vitamin K, which is essential to promote blood clotting.
Rationale 4: The stimulus for vitamin K rests with an injection, not a liquid form, to promote blood clotting and stimulate intestinal synthesis of the vitamin.
