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
A fundus that is palpable to the right of the midline can indicate a distended bladder. After childbirth, it’s common for women to have difficulty emptying their bladder. If the bladder becomes too full, it can push the uterus to one side.
Choice B rationale
Frequent uterine contractions are not typically associated with a distended bladder. After childbirth, it’s normal for women to experience contractions as the uterus begins to shrink back to its pre-pregnancy size.
Choice C rationale
Increased thirst is not typically a sign of a distended bladder. It’s common for women to feel thirsty as their body adjusts after childbirth.
Choice D rationale
Less than 2.5 cm of rubra lochia on the perineal pad is not typically a sign of a distended bladder. Lochia is the vaginal discharge women experience after childbirth. It’s not related to bladder function.
Correct Answer is D
Explanation
Choice A rationale
Neonatal Abstinence Syndrome (NAS) is a group of problems that occur in a newborn who was exposed to addictive opiate drugs while in the mother’s womb. While NAS can pose risks to a newborn, it is not considered the greatest risk.
Choice B rationale
Developmental Dysplasia of the Hip (DDH) is a condition where the “ball and socket” joint of the hip does not properly form in babies and young children. While DDH can pose risks to a newborn, it is not considered the greatest risk.
Choice C rationale
Subgaleal hemorrhage is a rare but potentially lethal condition in newborns, usually resulting from vacuum-assisted delivery. While it can pose risks to a newborn, it is not considered the greatest risk.
Choice D rationale
Congenital cardiac defects are the most common type of birth defect. They can alter the way blood flows through the heart and pose a significant risk to a newborn.
