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 A
Explanation
Choice A rationale
Methylergonovine is a medication used to prevent postpartum hemorrhage. It works by causing the uterus to contract, which helps to control bleeding and expel any remaining placental fragments.
Choice B rationale
While infection control is important in the postpartum period, methylergonovine is not specifically used to prevent postpartum infection.
Choice C rationale
Methylergonovine does not prevent hypertension. In fact, it can cause hypertension as a side effect.
Choice D rationale
Methylergonovine is not used to prevent thromboembolic events. Its primary use is to prevent and control postpartum hemorrhage.
Correct Answer is A
Explanation
Choice A rationale
Regular physical activity plays a key role in managing gestational diabetes. The American College of Obstetricians and Gynecologists (ACOG) recommends aiming for 150 minutes of moderate-level exercise each week during pregnancy. Reducing the exercise schedule to 3 days a week may not provide the recommended amount of physical activity needed to manage gestational diabetes effectively.
Choice B rationale
Glyburide is an oral medication that can be used to manage gestational diabetes when diet and exercise are not enough. It is usually taken before breakfast or the first main meal of the day.
Choice C rationale
This statement is correct. Women who have had gestational diabetes have an increased risk of developing type 2 diabetes later in life.
Choice D rationale
This statement is correct. A diet that includes about 40% to 45% carbohydrates is recommended for managing gestational diabetes.
