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,B,C
Explanation
Choice A rationale
Checking the newborn’s capillary blood glucose level is important, especially for a large for gestational age newborn. Large for gestational age newborns are at risk for hypoglycemia (low blood sugar) after birth. Therefore, regular monitoring of the newborn’s blood glucose level is crucial.
Choice B rationale
Placing the newborn under a radiant warmer can help regulate the baby’s body temperature. Newborns, especially those who are large for gestational age, may have difficulty maintaining their body temperature after birth. A radiant warmer can provide the extra warmth the baby needs.
Choice C rationale
Monitoring the newborn’s temperature is important as newborns can lose heat rapidly, they don’t have the ability to control their body temperature as adults do. Temperature regulation in newborns is important to help them stay healthy and comfortable.
Choice D rationale
Monitoring the newborn’s color and frequency of bowel movements is not directly related to the condition described. While it’s an important aspect of newborn care, it’s not a priority in this scenario.
Correct Answer is A
Explanation
Choice A rationale
This is the correct answer. In infants of mothers with poorly controlled diabetes, hyperinsulinemia can lead to increased oxygen consumption and metabolic rate, which can contribute to the development of respiratory distress syndrome.
Choice B rationale
Increased blood viscosity is not the most likely cause of respiratory distress in a macrosomic newborn of a mother with poorly controlled diabetes.
Choice C rationale
A brachial plexus injury is a potential complication of delivery for macrosomic infants, but it is not a cause of respiratory distress syndrome.
Choice D rationale
Increased deposits of fat in the chest and shoulder areas can make delivery more difficult and can increase the risk of birth injuries, but they are not the most likely cause of respiratory distress syndrome in a macrosomic newborn of a mother with poorly controlled diabetes.
