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?
The client's blood does not contain the Rh factor, so she produces anti-Rh antibodies that cross the placental barrier and cause hemolysis of red blood cells in newborns.
The client's blood contains the Rh factor, and the newborn's does not, and antibodies that destroy red blood cells are formed in the fetus.
The client has a history of receiving a transfusion with Rh-negative blood.
The client's anti-A and anti-B antibodies cross the placenta and cause the destruction of the fetal red blood cells.
The Correct Answer is A
Choice A rationale:
Rh incompatibility occurs when an Rh-negative client is exposed to Rh-positive fetal blood, typically during a prior pregnancy or delivery. The client’s immune system produces anti-Rh antibodies that cross the placenta in subsequent pregnancies, attacking the Rh-positive red blood cells of the fetus. This hemolysis releases bilirubin, leading to hyperbilirubinemia in the newborn.
Choice B rationale:
Rh incompatibility only occurs when the client is Rh-negative and the fetus is Rh-positive. An Rh-positive client will not form antibodies against an Rh-negative fetus, as their immune system recognizes the Rh factor as normal.
Choice C rationale:
This choice is not related to the mechanism of Rh incompatibility. Receiving a transfusion with Rh-negative blood would not cause the mother's immune system to produce anti-Rh antibodies or lead to Rh incompatibility with her newborn.
Choice D rationale:
This choice describes the ABO blood group system, not the Rh factor. ABO incompatibility can occur when a mother with blood type O (producing anti-A and anti-B antibodies) has a newborn with blood type A, B, or AB, leading to hemolysis of the fetal red blood cells. However, the question specifically mentions Rh incompatibility, which involves the Rh factor, not the ABO system.

Correct Answer is ["A","B","D"]
Explanation
Choice A rationale:
The nurse should ask the client if they are taking over-the-counter medications because ibuprofen is also available over-the-counter. It is important to know if the client is already taking ibuprofen or any other non-prescription pain relievers to avoid potential drug interactions or overdosing.
Choice B rationale:
The nurse should inquire about the client's history of gastric problems because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal irritation and bleeding. If the client has a history of gastric ulcers or other gastric issues, the nurse may need to consider an alternative pain relief option.
Choice C rationale:
The question about contraception is not directly related to administering ibuprofen for postpartum cramping. It is essential to provide adequate pain relief, but the method of contraception the client plans to use is not relevant to the administration of the medication.
Choice D rationale:
This question is pertinent because NSAIDs like ibuprofen can cause fluid retention and potentially worsen hypertension.
Choice E rationale:
The presence of cataracts is not relevant to the administration of ibuprofen for postpartum cramping. Cataracts are a concern with eye health and are not associated with taking this pain medication.
Correct Answer is A
Explanation
The correct answer is A. Apply an ice pack to the affected area. Ice packs are recommended during the first 24 hours after birth to decrease swelling and help with pain.
Choice A reason: Applying an ice pack to the episiotomy site helps reduce swelling and provides pain relief. This is the standard care within the first 24 hours postpartum.
Choice B reason: A warm sitz bath is generally recommended after the first 24 hours following birth. It is not the best immediate action for unrelieved pain shortly after delivery.
Choice C reason: While maintaining cleanliness with a squeeze bottle of antiseptic solution is important for preventing infection, it does not provide the immediate pain relief needed for unrelieved episiotomy pain.
Choice D reason: Heat application, such as placing a hot pack, is not advised within the first 24 hours postpartum because it can increase the risk of swelling and bleeding.
