The nurse is beginning the examination of a 4-month-old infant. She takes the infant from the mother's arms to do the exam. Where should the nurse place the infant for the exam?

In the crib facing the mom.

Explanation:

The infants require the proper medical attention and parental support during any examination. The parental support makes the infant comfortable and reduces his fear.

If the nurse wants to perform any examination on the infant she must place the infant with the position that can allow the infant to see his parent. This provide support to the infant. The crib facing the mom is quite comfortable that keeps the parent in the view.

Thus, the answer is in the crib facing the mom.
