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

Lethargy in a child who is 2 days postoperative following the insertion of a ventriculoperitoneal shunt could indicate a serious problem such as shunt malfunction or infection, and should be the priority.

Choice B rationale

A respiratory rate of 20/min is within the normal range for a 4-year-old child and is not typically a cause for concern.

Choice C rationale

Lying flat on the unaffected side is not typically a cause for concern following ventriculoperitoneal shunt surgery.

Choice D rationale

A urine output of 50 mL in 2 hr is within the normal range for a 4-year-old child and is not typically a cause for concern.

Choice A rationale

Applying lotion to the newborn’s skin twice per day is not necessary during phototherapy. The main goal of phototherapy is to reduce the level of bilirubin in the newborn’s blood. Applying lotion can interfere with the effectiveness of the light therapy and can cause the newborn’s skin to overheat.

Choice B rationale

Monitoring the newborn’s blood glucose level hourly is not necessary during phototherapy unless the newborn has a specific condition that requires close monitoring of blood glucose levels. Phototherapy does not directly affect blood glucose levels.

Choice C rationale

Encouraging the newborn to breastfeed every 2 hours is an important part of the care plan for a newborn undergoing phototherapy. Frequent feeding can help to promote the excretion of bilirubin through the newborn’s stool.

Choice D rationale

Maintaining the newborn in a prone position is not necessary during phototherapy. The newborn should be placed in a variety of positions to ensure that all areas of the skin are exposed to the light.
