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 B
Explanation
Choice A rationale
While it’s true that a newborn’s stools will transition in color, it typically takes a few days longer than one or two. Initially, the stools are a greenish-black color known as meconium. Over the next few days, as the baby begins digesting breast milk or formula, the stools will gradually transition to a yellow color.
Choice B rationale
This statement is correct. After childbirth, the breasts undergo a process known as engorgement when they start to produce milk. This can cause the breasts to become harder, warmer, and more tender. This is a normal part of the postpartum period and is a sign that the body is preparing to feed the baby.
Choice C rationale
While it’s true that abdominal discomfort generally decreases over time after childbirth, it’s important to note that the rate of decrease can vary greatly among individuals. Factors such as the type of delivery (vaginal or cesarean), individual pain tolerance, and the presence of any complications can all influence the rate of decrease in abdominal discomfort.
Choice D rationale
While it’s true that many women do feel more energetic as their bodies recover from childbirth, this is not always the case. Factors such as sleep deprivation, hormonal changes, and the physical demands of caring for a newborn can all contribute to feelings of fatigue and exhaustion. Therefore, while some women may feel more energetic, others may continue to feel tired for several weeks or even months after giving birth.
Correct Answer is D
Explanation
Choice A rationale
Applying cold compresses 20 minutes before each feeding may not be the most effective way to manage breast engorgement. Cold compresses can help to reduce swelling and relieve pain, but they do not address the underlying cause of engorgement, which is the accumulation of milk in the breasts.
Choice B rationale
Drinking herbal tea to reduce engorgement is not a proven method. While some herbs are believed to have galactagogue properties (increase milk production), they do not directly address breast engorgement. Furthermore, the safety and efficacy of many herbal remedies are not well-studied, and some may have side effects.
Choice C rationale
Letting the baby drain one breast at each feeding can help to alleviate engorgement, but it may not be sufficient if the feedings are spaced too far apart. The breasts continue to produce milk between feedings, and if the milk is not removed, engorgement can occur.
Choice D rationale
Feeding the baby every 2 hours can help to manage breast engorgement. Regular feedings help to ensure that the milk is being removed from the breasts, preventing the buildup that leads to engorgement.
