A nurse is caring for a client who has just delivered her first newborn. The nurse anticipates hyperbilirubinemia due to Rh incompatibility. The nurse should understand that hyperbilirubinemia occurs with Rh incompatibility for which of the following reasons?

Choice A rationale:

Keeping the newborn dressed while receiving phototherapy is not recommended because the baby's skin needs to be exposed to the light to effectively treat hyperbilirubinemia. Direct exposure to light helps break down the excess bilirubin in the baby's blood, leading to its excretion.

Choice B rationale:

Applying lotion to the skin twice daily is contraindicated during phototherapy. Lotions and creams can block the light from reaching the skin and hinder the therapeutic effects of the phototherapy. The baby's skin should remain exposed to the light for optimal treatment.

Choice C rationale:

Maintaining an eye mask over the newborn's eyes is essential during phototherapy. The eyes are sensitive to light, and prolonged exposure to the phototherapy light can lead to eye damage. Using an eye mask protects the baby's eyes while allowing the rest of the body to receive the necessary light treatment.

Choice D rationale:

Maintaining the phototherapy during blood draws is crucial to ensure continuous treatment of hyperbilirubinemia. Interrupting the phototherapy during blood draws might result in the rebound of bilirubin levels, which can be harmful to the baby.

Choice A rationale:

Assisting the client to void is a priority intervention in this situation. A full bladder can displace the uterus and prevent it from contracting effectively, leading to a boggy and high- positioned fundus. After the client empties her bladder, the nurse should reassess the fundus to ensure it has descended to its appropriate location, which is usually at or just below the level of the umbilicus.

Choice B rationale:

Documenting the findings as within normal limits is incorrect because a firm, displaced fundus that is 3 cm above the umbilicus is not considered normal. This finding indicates that the uterus is not contracting adequately, and the nurse should take appropriate actions to address the issue.

Choice C rationale:

Gently massaging the client's fundus is not the correct intervention in this case. Massaging a firm fundus could cause uterine irritation and should be avoided. Instead, the nurse should encourage the client to empty her bladder, which often helps the uterus contract and descend to its proper position.

Choice D rationale:

Encouraging the client to ambulate may be helpful in some cases to promote uterine contractions and involution. However, in this situation, the priority is to address the full bladder, as it is a common cause of a displaced and high fundus shortly after delivery.
