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 C
Explanation
Choice A rationale
Neonatal abstinence syndrome is a condition that results from withdrawal from exposure to narcotics. It is not related to the newborn’s weight.
Choice B rationale
While a yellowish skin tone may indicate jaundice, this is not directly related to the newborn’s weight. Jaundice is caused by an excess of bilirubin, a yellow-orange substance in the blood.
Choice C rationale
Newborns with low birth weight are at risk for hypoglycemia because they have less stored glycogen. They may use up their glucose stores quickly and not have enough intake to maintain their blood glucose levels.
Choice D rationale
Neonatal sepsis is a severe infection in an infant less than 28 days old. It is not directly related to the newborn’s weight but can be associated with maternal infection.
Correct Answer is ["A","B","D"]
Explanation
Choice A rationale
Cerebral manifestations such as a mild headache can be a sign of preeclampsia, a pregnancy complication characterized by high blood pressure and signs of damage to another organ system, often the liver and kidneys. This should be reported to the provider.
Choice B rationale
Gastrointestinal assessment findings such as heartburn can be common in pregnancy due to hormonal changes and the growing uterus pressing on the stomach. However, severe or persistent heartburn may indicate a more serious condition like gastroesophageal reflux disease (GERD) or preeclampsia. This should be reported to the provider.
Choice C rationale
Respiratory rate alone, without knowing whether it’s increased, decreased, or normal, is not enough information to determine if it should be reported to the provider.
Choice D rationale
Deep tendon reflexes can be hyperactive in clients with preeclampsia. An increase in deep tendon reflexes can be a sign of worsening preeclampsia and should be reported to the provider.
