The nurse is caring for a patient who gave birth to an infant with a congenital heart anomaly. The patient asks the nurse when such anomalies occur during development. Which response by the nurse is most accurate?

A. Encouraging the child to drink fluids to stay hydrated is incorrect because while hydration is important, the priority is identifying and managing potential increased intracranial pressure (ICP). Giving fluids before assessing neurological status may delay recognition of a serious complication.

B. Positioning the child in a flat supine position is incorrect because a flat supine position can actually increase ICP. Postoperative positioning for brain surgery typically involves head elevation (30 degrees) to promote venous drainage and reduce ICP, unless contraindicated.

C. Administering an antiemetic to control vomiting is incorrect as controlling vomiting is secondary. Vomiting can be a sign of increased ICP, so addressing the underlying cause is more important than treating symptoms alone.

D. Assessing the child's neurological status and checking for signs of increased intracranial pressure is correct. Vomiting and headache after brain surgery are red flags for increased ICP, which can lead to life-threatening complications such as brain herniation. Priority nursing actions include frequent neurological assessments (level of consciousness, pupil size and reactivity, motor function), monitoring vital signs for changes in blood pressure, pulse, and respiration (Cushing’s triad), notifying the healthcare provider immediately if ICP is suspected, and implementing interventions to reduce ICP, such as proper positioning, oxygenation, and minimizing stimuli.

A. Caput succedaneum is incorrect because this condition is a diffuse swelling of the scalp that crosses suture lines and is caused by pressure during delivery. It usually resolves on its own within a few days and does not significantly increase bilirubin levels or require phototherapy.

B. Neither condition increases bilirubin levels is incorrect because cephalohematoma can significantly elevate bilirubin due to red blood cell breakdown within the localized hematoma. While caput succedaneum has minimal impact, cephalohematoma can contribute to hyperbilirubinemia.

C. Phototherapy is more likely needed with caput succedaneum is incorrect because the swelling in caput succedaneum does not contain trapped blood and therefore does not cause significant hemolysis or increase bilirubin levels.

D. Cephalohematoma increases the risk of hyperbilirubinemia is correct because cephalohematoma is a collection of blood between the skull and periosteum that is confined by suture lines. The trapped red blood cells break down over time, releasing bilirubin into the bloodstream. This delayed bilirubin rise can become significant and often requires phototherapy to prevent complications such as kernicterus.
