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 D
Explanation
Choice a reason:
While ultrasound can be used for estimating fetal age, at 36 weeks of gestation, this is not the primary reason for performing an ultrasound before an amniocentesis. Fetal age is usually estimated earlier in the pregnancy to help with dating the pregnancy and determining the due date.
Choice b reason:
Determining if there is more than one fetus is typically established earlier in the pregnancy. By 36 weeks, the presence of multiples would already be known, so this would not be the primary reason for an ultrasound before an amniocentesis at this stage.
Choice c reason:
An ultrasound can be used as a screening tool for spina bifida, but it is not the main reason for an ultrasound before an amniocentesis at 36 weeks. Screening for spina bifida and other anomalies is usually done during the second trimester.
Choice d reason:
The primary reason for an ultrasound before an amniocentesis is to identify the location of the placenta and fetus. This information is crucial to ensure the safety of both the mother and the fetus during the procedure by avoiding injury to the placenta and ensuring the amniotic needle is inserted in a safe location.
Correct Answer is A
Explanation
Choice a reason:
Hydration is crucial during pregnancy, especially for those with preeclampsia. Adequate water intake helps maintain blood volume and reduce blood viscosity, which can help manage blood pressure levels. Drinking 48 to 64 ounces of water daily is recommended to support the increased blood volume needed during pregnancy and to help prevent dehydration, which can exacerbate preeclampsia symptoms.
Choice b reason:
While reducing salt intake can be beneficial for managing blood pressure, it is not necessary to completely avoid salting foods during cooking. Instead, moderation is key. Excessive salt can lead to water retention, which can worsen preeclampsia, but some salt is needed for electrolyte balance and proper body function.
Choice c reason:
Protein is an essential nutrient for fetal growth and the repair and maintenance of maternal tissues. A daily intake of 40 to 50 grams of protein is generally recommended during pregnancy. However, for those with preeclampsia, protein needs may be higher due to potential protein loss in the urine. It's important to monitor protein intake and adjust as needed under medical guidance.
Choice d reason:
Limiting the intake of whole grains, raw fruits, and vegetables is not recommended. These foods provide essential nutrients, fiber, and antioxidants that are beneficial for both maternal and fetal health. They should be included as part of a balanced diet unless there are specific dietary restrictions advised by a healthcare provider.
