A nurse is caring for a client who is 6 hr postpartum. The client is Rh-negative and her newborn is Rh-positive. The client asks why an indirect Coombs test was ordered by the provider. Which of the following is an appropriate response by the nurse?

Choice A reason: This client should be seen first, as she has the most urgent and acute problem that requires immediate assessment and intervention. Severe pain after a cesarean birth can indicate infection, hemorrhage, or wound dehiscence, which are serious complications that can affect the client's recovery and well-being. The nurse should evaluate the client's pain level, location, and characteristics, and administer analgesics as prescribed. The nurse should also inspect the incision site, monitor the vital signs and lochia, and provide comfort measures.

Choice B reason: This client should be seen second, as she has a chronic and stable problem that requires ongoing monitoring and management. Preeclampsia is a hypertensive disorder of pregnancy that can cause complications, such as eclampsia, HELLP syndrome, or placental abruption. However, this client has a mild elevation of blood pressure that does not indicate severe preeclampsia or imminent eclampsia. The nurse should check the client's urine protein, reflexes, and edema, and report any signs of worsening condition to the provider.

Choice C reason: This client should be seen third, as she has a normal and expected outcome that requires routine education and discharge planning. A vaginal delivery without complications does not pose any significant risk or concern for the client or the newborn. The nurse should review the discharge instructions, such as follow-up appointments, self-care, breastfeeding, and warning signs, and answer any questions that the client may have.

Choice D reason: This client should be seen last, as she has a common and benign finding that requires reassurance and documentation. A scant amount of lochia after a vaginal birth is normal and expected, as it reflects the healing and involution of the uterus. The nurse should assess the color, odor, and consistency of the lochia, and provide perineal care and hygiene education to the client.

Choice A reason: This statement is incorrect, as it describes the direct Coombs test, not the indirect Coombs test. The direct Coombs test is performed on the newborn's blood, and it detects the presence of maternal antibodies that have attached to the newborn's red blood cells. The direct Coombs test can help diagnose hemolytic disease of the newborn, which is a condition where the maternal antibodies destroy the newborn's red blood cells, causing anemia and jaundice.

Choice B reason: This statement is incorrect, as it is not the purpose of the indirect Coombs test, but rather a possible complication of hemolytic disease of the newborn. Kernicterus is a severe form of jaundice that occurs when the bilirubin level in the blood is very high, and it can cause brain damage, deafness, or death. Kernicterus can be prevented by treating the jaundice with phototherapy or exchange transfusion.

Choice C reason: This statement is correct, as it describes the indirect Coombs test, which is performed on the mother's blood, and it detects the presence of Rh-positive antibodies that have formed in response to the exposure to the Rh-positive blood of the newborn. The indirect Coombs test can help identify the risk of hemolytic disease of the newborn, and guide the administration of Rh immunoglobulin, which is a medication that prevents the formation of Rh-positive antibodies.

Choice D reason: This statement is incorrect, as it is not possible for the newborn to have Rh-negative antibodies, since the newborn has Rh-positive blood. Rh-negative antibodies are produced by Rh-negative individuals who have been exposed to Rh-positive blood, such as Rh-negative mothers who have Rh-positive newborns. Rh-negative antibodies can cross the placenta and attack the Rh-positive red blood cells of the newborn, causing hemolytic disease of the newborn.
