Which infant would be more likely to have Rh incompatibility?

Placing eye shields over the newborn’s closed eyes. This is because phototherapy can cause eye damage and irritation to the newborn, so eye protection is essential.

Choice A is wrong because oil-based lotion can increase the absorption of heat and cause burns to the newborn’s skin.

Choice B is wrong because limiting the newborn’s intake of milk can cause dehydration and increase the risk of hyperbilirubinemia.

Choice D is wrong because changing the newborn’s position every 4 hours is not frequent enough to prevent pressure ulcers and ensure even exposure to the light.

Normal ranges for bilirubin levels in newborns are 1 to 12 mg/dL for term infants and 3 to 14 mg/dL for preterm infants. Phototherapy is usually indicated when the bilirubin level exceeds 15 mg/dL for term infants and 10 mg/dL for preterm infants.

This is because a patent ductus arteriosus is a congenital heart defect that involves a defect in which the fetal shunt between the aorta and the pulmonary artery fails to close. This causes a continuous machinery-like murmur that can be heard on auscultation.

Choice A is wrong because pulmonary stenosis is a narrowing of the pulmonary valve or artery that obstructs blood flow to the lungs. It causes a systolic ejection murmur that is best heard at the upper left sternal border.

Choice C is wrong because the ventricular septal defect is a hole in the wall between the ventricles that allows blood to flow from the left to the right side of the heart. It causes a loud, harsh holosystolic murmur that is best heard at the left lower sternal border.

Choice D is wrong because coarctation of the aorta is a narrowing of the aorta that reduces blood flow to the lower body. It causes a systolic murmur that radiates to the back and weak or absent femoral pulses.
