A nurse is providing care for a patient who has recently given birth to her first child. The patient has a history of receiving a transfusion with Rh-negative blood.
The nurse expects hyperbilirubinemia due to Rh incompatibility.
What is the reason for hyperbilirubinemia occurring with Rh incompatibility?
The nurse expects hyperbilirubinemia due to Rh incompatibility.
Gastrointestinal assessment findings.
Respiratory rate.
Deep tendon reflexes.
The Correct Answer is C
Choice A rationale
The patient’s anti-A and anti-B antibodies crossing the placenta and causing the destruction of the fetal red blood cells is related to ABO incompatibility, not Rh incompatibility.
Choice B rationale
If the patient’s blood contains the Rh factor and the newborn’s does not, Rh incompatibility would not occur. Rh incompatibility happens when the mother’s blood does not contain the Rh factor (Rh-negative), but the baby’s blood does contain the Rh factor (Rh-positive).
Choice C rationale
The patient’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. This is the correct reason for hyperbilirubinemia occurring with Rh incompatibility.
Choice D rationale
The patient’s blood containing anti-Rh antibodies that attack the newborn’s red blood cells is a result of Rh incompatibility, but it does not explain why hyperbilirubinemia occurs.
Hyperbilirubinemia occurs due to the breakdown of the extra red blood cells, leading to an increase in bilirubin levels.

Correct Answer is D
Explanation
Choice A rationale
A rapid decline in human chorionic gonadotropin (hCG) levels is not typically associated with a hydatidiform mole. In fact, hCG levels are usually abnormally high with this condition.
Choice B rationale
Profuse, clear vaginal discharge is not a typical finding in a client with a hydatidiform mole. The client may experience vaginal bleeding, but it is often described as resembling ‘prune juice’ or 'grape clusters’56.
Choice C rationale
An irregular fetal heart rate is not a typical finding in a client with a hydatidiform mole, as this condition involves the abnormal growth of placental tissue, often without the development of a viable fetus.
Choice D rationale
Excessive uterine enlargement is a common finding in a client with a hydatidiform mole. This is due to the overgrowth of the placental tissue.
