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
The correct answers are A. Start breastfeeding with the nipple that is less sore, B. Change the infant’s position on the nipples, and C. Apply breast milk to the nipples before each feeding.
Choice A rationale:
Starting breastfeeding with the nipple that is less sore can help reduce discomfort. The baby tends to suck more vigorously at the beginning of a feeding, so starting with the less sore nipple can minimize pain.
Choice B rationale:
Changing the infant’s position on the nipples can help distribute the pressure more evenly and prevent further irritation of sore areas. Different positions can also help ensure a better latch.
Choice C rationale:
Applying breast milk to the nipples before each feeding can soothe and promote healing of sore nipples. Breast milk has natural antibacterial properties and can help keep the nipples moisturized.
Choice D rationale:
Massaging the breasts and nipples prior to feeding is not typically recommended for reducing nipple soreness. It can potentially cause more irritation and discomfort.
Choice E rationale:
Placing breast pads inside the nursing bra can help absorb leakage and keep the nipples dry, but it does not directly reduce soreness during breastfeeding. It is more of a preventive measure to maintain hygiene.
Correct Answer is D
Explanation
Choice A rationale
While male condoms are a popular method of contraception due to their accessibility and ease of use, they are not the most reliable method. They have a higher failure rate compared to other methods, particularly if not used correctly or consistently.
Choice B rationale
Oral contraceptives are more reliable than male condoms, but they require consistent daily use and can be affected by other factors such as certain medications or vomiting/diarrhea.
Choice C rationale
A diaphragm with spermicide is a barrier method of contraception that is less reliable than hormonal methods or intrauterine devices. It also requires correct placement and use with every act of intercourse.
Choice D rationale
An intrauterine device (IUD) is one of the most reliable methods of contraception. Once inserted by a healthcare provider, it provides long-term, reversible contraception without requiring daily adherence.
