A nurse is collecting data from an infant at a well-child visit.
The nurse should expect the infant to double his birth weight by which of the following ages?

Choice A rationale

Feeding an infant with spina bifida through an NG tube may not be necessary unless the child has specific feeding difficulties or other health issues. Spina bifida does not typically affect a child’s ability to eat or swallow.

Choice B rationale

Placing an infant with spina bifida in a prone position can help protect and care for the lesion on their back. It can also help prevent pressure sores and promote comfort.

Choice C rationale

Covering the infant’s lesion with a dry cloth is not typically recommended. The lesion should be kept clean and moist to promote healing and prevent infection.

Choice D rationale

While physical therapy and exercises can be beneficial for children with spina bifida, performing range-of-motion exercises to the infant’s hips may not be necessary unless specifically recommended by a healthcare provider.

Step 1: The nurse needs to administer 1mg of vitamin K. The available vitamin K injection is 1 mg per 0.5 mL.

Step 2: To find out how many mL the nurse should administer, we divide the required dose by the concentration of the injection. So, 1 mg ÷ (1 mg/0.5 mL).

Step 3: This simplifies to 1 mg × (0.5 mL/1 mg).

Step 4: The mg units cancel out, leaving us with 0.5 mL. So, the nurse should administer 0.5 mL of the vitamin K injection per dose.
