A nurse is caring for a client who is 6 hours 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?
"It detects positive antibodies in the mother's blood."
"It detects Rh-negative antibodies in the newborn's blood."
"It determines if kernicterus will occur in the newborn."
"It determines the presence of maternal antibodies in the newborn's blood."
The Correct Answer is A
Choice A reason: The indirect Coombs test is used to screen for antibodies in the mother's blood that could potentially cause hemolytic disease in the newborn if they are Rh-positive. A positive result indicates that the mother has developed antibodies that could cross the placenta and attack the red blood cells of an Rh-positive fetus.
Choice B reason: The indirect Coombs test does not detect Rh-negative antibodies in the newborn's blood. Instead, it is used to detect antibodies in the mother's blood. The direct Coombs test is used to detect antibodies that are already attached to the red blood cells of the newborn.
Choice C reason: The indirect Coombs test does not determine if kernicterus will occur in the newborn. Kernicterus is a form of brain damage that can result from very high levels of bilirubin in a baby's blood. It is not directly related to the presence of antibodies detected by the indirect Coombs test.
Choice D reason: The indirect Coombs test does not determine the presence of maternal antibodies in the newborn's blood. This is assessed by the direct Coombs test, which checks for antibodies bound to the surface of the newborn's red blood cells, indicating that the immune system is attacking them.

Correct Answer is A
Explanation
Choice A reason:
In the case of a client with painless, bright red vaginal bleeding at 38 weeks of gestation, the priority is to stabilize the client's condition. Initiating IV access is crucial as it allows for rapid administration of fluids or blood products to address potential hypovolemia and to prepare for the possibility of an emergency cesarean section if needed. The client's low blood pressure and elevated heart rate suggest that she may be experiencing hypovolemia, which can quickly lead to hypovolemic shock if not treated promptly.
Choice B reason:
While obtaining informed consent is important before any surgical procedure, it is not the immediate priority. The priority is to stabilize the client, and consent can be obtained concurrently with other stabilizing actions or by another member of the healthcare team.
Choice C reason:
Inserting an indwelling urinary catheter is a supportive measure that can be necessary during labor or before surgery to keep the bladder empty, reducing the risk of bladder injury during a cesarean section and monitoring urine output as an indicator of renal perfusion. However, it is not the first priority in the presence of significant vaginal bleeding.
Choice D reason:
Preparing the abdominal and perineal areas is part of the preoperative procedure for a cesarean section. This action would follow after the client has been stabilized and a decision for surgery has been made.
Correct Answer is A
Explanation
Choice a) reason:
Timing the administration of pain medication can help minimize the amount of medication that passes into the breast milk. By scheduling pain relief around breastfeeding times, the nurse can ensure that the peak concentration of the medication in the blood (and therefore potentially in the milk) does not coincide with the baby's feeding times. This approach helps manage the mother's pain while also protecting the newborn from unnecessary exposure to medication.
Choice b) reason:
While managing pain is important for the mother's comfort and recovery, stating that she needs to take medication without considering her concerns about breastfeeding may not be supportive or respectful of her wishes. It's essential to address her concerns and provide options that align with her breastfeeding goals.
Choice c) reason:
It is true that all medications can be found in breast milk to some extent; however, the levels can vary widely based on the medication's properties. The nurse should provide information about the specific medication's safety during breastfeeding and discuss any potential risks with the mother.
Choice d) reason:
Informing the mother that she has the option of not taking pain medication addresses her autonomy in decision-making. However, it's also important for the nurse to discuss the potential consequences of untreated pain, such as impaired ability to care for the newborn and delayed recovery.
