A nurse is collecting data about reflexes from a newborn. Which of the following actions should the nurse take to elicit the newborn's Moro reflex?

Choice A rationale:

Cephalhematoma is the correct answer because it presents as a swelling on the newborn's head confined to one cranial bone and does not cross suture lines. It usually resolves on its own within a few weeks to months but can increase the risk of jaundice due to the breakdown of red blood cells in the hematoma.

Choice B rationale:

Nevus flammeus, also known as a port-wine stain, is a type of vascular birthmark. It presents as a flat, pink, or red mark on the skin and does not involve swelling of the head. This choice is unrelated to the findings described in the question and is therefore incorrect.

Choice C rationale:

Caput succedaneum refers to a diffuse, soft tissue swelling of the scalp that does cross suture lines. It is caused by pressure on the head during delivery, leading to edema and bruising. It typically resolves within a few days after birth.

Choice D rationale:

Molding refers to the shaping of the fetal head during childbirth as it passes through the birth canal. It may cause temporary elongation or molding of the head, but it does not present as a localized swollen area. This choice is not applicable to the findings mentioned in the question and is thus incorrect.

Choice A rationale:

Placing the newborn in a radiant warmer may provide warmth, but it does not address the observed signs of respiratory distress, jitteriness, and lethargy. These signs indicate potential respiratory and neurological issues, which need to be assessed and managed promptly.

Choice B rationale:

Initiating phototherapy is not appropriate for the observed signs of respiratory distress, jitteriness, and lethargy. Phototherapy is used to treat neonatal jaundice caused by elevated bilirubin levels, which is not evident from the given information.

Choice C rationale:

The nurse should obtain blood glucose by heel stick to assess the newborn's blood sugar levels. The signs of jitteriness and lethargy may be indicative of hypoglycemia (low blood sugar), which is common in newborns. Early detection and intervention are crucial to prevent complications and ensure the baby's well-being.

Choice D rationale:

Measuring the newborn's blood pressure is not the priority at this moment. The observed signs suggest respiratory distress and potential hypoglycemia, which need immediate attention. Blood pressure assessment may be important later on, but it is not the first action the nurse should take based on the given information.
