Infants in whom cephalohematomas develop are at increased risk for:

Choice A rationale

Caput succedaneum is swelling of the soft tissues of the newborn's scalp, often caused by pressure during vaginal delivery. It is a separate condition from cephalohematoma, which involves bleeding between the periosteum and the skull bone. Therefore, cephalohematoma does not increase the risk for caput succedaneum.

Choice B rationale

Jaundice, or hyperbilirubinemia, is a common condition in newborns due to the breakdown of fetal red blood cells and the immature liver's inability to efficiently process bilirubin. Cephalohematomas involve the rupture of blood vessels, leading to an increased breakdown of red blood cells. This releases more bilirubin into the bloodstream, thus elevating the risk of jaundice in infants with cephalohematomas. Normal total bilirubin levels in newborns range from 1 to 12 mg/dL, varying with age in days.

Choice C rationale

Infection is a risk associated with any break in the skin or invasive procedure, but a cephalohematoma itself is a collection of blood beneath the periosteum and does not inherently create an open wound or direct pathway for infection. While infection of a cephalohematoma is possible, it is not a primary increased risk associated with its development.

Choice D rationale

Erythema toxicum is a common, benign skin rash seen in newborns, characterized by small, yellow-white papules or pustules surrounded by red skin. Its etiology is unknown but it is thought to be an inflammatory reaction of the hair follicles. It is not related to the presence or development of a cephalohematoma.
