A nurse is reinforcing teaching about comfort measures for breast engorgement with a client who is postpartum and is bottle-feeding her newborn. Which of the following statements by the client indicates a need for further teaching?

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:

Acrocyanosis, or bluish discoloration of the hands and feet, is common in the first 24 hours after birth and is typically not a cause for concern.

Choice B rationale:

A newborn not voiding within 18 hours may need evaluation, but it is not as urgent as a potential infection.

Choice C rationale:

A newborn who is 24 hours old and has not passed meconium is not the most critical concern among the options provided. While meconium (the baby's first stool) should be passed within the first 24-48 hours, a slight delay may not be an immediate cause for concern.

Choice D rationale:

The nurse should prioritize seeing the newborn with an axillary temperature of 37.8°C (100° F), as this could indicate an infection or other serious condition requiring immediate attention.
