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 D
Explanation
Choice A rationale:
The client's statement about needing to have the IUD replaced each year is incorrect. The lifespan of most IUDs is longer than a year. Copper IUDs can last up to 10 years, and hormonal IUDs can last between 3 to 7 years, depending on the brand.
Choice B rationale:
The client's statement about needing to apply a spermicide prior to intercourse is unrelated to the correct use of an intrauterine device (IUD) for contraception. Spermicides are not required when using an IUD.
Choice C rationale:
The client's statement about expecting periods to stop while having the IUD is incorrect. Hormonal IUDs can often lead to lighter periods, and in some cases, periods may stop altogether. However, with a copper IUD, periods usually remain the same.
Choice D rationale:
This is the correct choice. The client's statement indicates an understanding of the teaching. Checking for the string each month after menstruation is crucial because it confirms that the IUD is still in place, reducing the risk of unintended pregnancy.
Correct Answer is D
Explanation
Choice A rationale:
A client who gave birth 1 day ago and needs Rh(D) immune globulin should be seen soon but not necessarily first. Rh(D) immune globulin is administered to Rh-negative mothers with Rh- positive infants to prevent isoimmunization in future pregnancies.
Choice B rationale:
A client who gave birth 3 days ago and reports breast fullness is likely experiencing normal postpartum breast engorgement. This client can be attended to after the client with more urgent symptoms.
Choice C rationale:
A client who gave birth 12 hours ago and reports an increase in urinary output might have diuresis, which is a common postpartum physiological change. Although this requires assessment, it is not as urgent as the client in choice D.
Choice D rationale:
The nurse should see the client who gave birth 8 hours ago and is saturating a perineal pad every hour first because excessive postpartum bleeding could indicate hemorrhage, a potentially life-threatening complication. Immediate assessment and intervention are crucial in this situation.
