A nurse is collecting data from a newborn and notes a swollen area on the head that does not cross the suture line. The nurse should document this finding as which of the following?
A.
Cephalhematoma.
B.
Nevus flammeus.
C.
Caput succedaneum.
D.
Molding.
The correct answer and Explanation is :
The correct answer is A. Cephalhematoma.
Cephalhematoma is a collection of blood between a newborn’s skull bone and its periosteum (the membrane covering the bone). It is caused by pressure during birth, often due to prolonged labor, forceps delivery, or vacuum extraction. The characteristic feature of cephalhematoma is that it is confined to one side of the head and does not cross the suture lines of the skull because the bleeding is restricted to the surface of the bone beneath the periosteum.
Here’s why the other options are incorrect:
B. Nevus flammeus (also known as a port-wine stain) is a congenital vascular malformation that presents as a flat, reddish or purplish mark on the skin, commonly on the face or neck. It is unrelated to trauma during birth and does not involve swelling or crossing of suture lines.
C. Caput succedaneum is a more generalized swelling of the scalp, often caused by pressure from the uterus or vaginal walls during delivery. Unlike cephalhematoma, caput succedaneum can cross the suture lines of the skull. It involves edema rather than a collection of blood and typically resolves within a few days after birth without intervention.
D. Molding refers to the shaping of the newborn’s head during passage through the birth canal. This process allows the skull bones to overlap slightly, facilitating delivery. Molding results in a temporary alteration in head shape but does not involve swelling or bleeding like cephalhematoma or caput succedaneum.
To summarize, cephalhematoma is a localized swelling due to bleeding between the skull bone and periosteum, which does not cross the suture line. This contrasts with caput succedaneum, which involves swelling that can cross suture lines, and molding, which is a normal, temporary head shaping without swelling.
