A nurse is assessing a newborn's head after a vaginal delivery. The nurse notes a soft, edematous area that crosses suture lines on the scalp. The parents ask how this differs from a cephalohematoma. Which of the following statements is correct?

A. Both caput succedaneum and cephalohematoma are superficial scalp swellings that are visible at birth, can cross suture lines, and generally resolve spontaneously within a few hours to a few days without any risk of complications is incorrect. While caput succedaneum crosses suture lines and resolves quickly, cephalohematoma does not cross suture lines and takes longer to resolve. B. Caput succedaneum is a collection of blood beneath the periosteum that is limited to a single cranial bone, does not cross suture lines, while cephalohematoma is a superficial scalp swelling that crosses suture lines is incorrect. This description reverses the characteristics of caput succedaneum and cephalohematoma. Caput succedaneum is a superficial edema that crosses suture lines, whereas cephalohematoma is a subperiosteal hemorrhage limited to one cranial bone. C. Caput succedaneum is usually firm and may be associated with bruising or ecchymosis, while cephalohematoma is a soft swelling that crosses suture lines is incorrect. Caput succedaneum is soft and edematous, not firm, and cephalohematoma does not cross suture lines. D. Caput succedaneum crosses suture lines and usually resolves within a few days without intervention, while cephalohematoma is a subperiosteal hemorrhage confined to one cranial bone that may take weeks to months to resolve and can slightly increase the risk of hyperbilirubinemia is correct. Caput succedaneum results from pressure on the fetal head during delivery, causing soft tissue edema, while cephalohematoma results from ruptured blood vessels under the periosteum and resolves more slowly, with a small risk of hyperbilirubinemia.
