A nurse is caring for a client who experienced a vaginal birth 12 hours ago. The nurse recognizes the client is in the dependent, taking-in phase of maternal postpartum adjustment. Which of the following findings should the nurse expect during this phase?

Choice a reason:
Elevated blood pressure is a primary indicator for preeclampsia, which is a condition characterized by hypertension and often proteinuria after 20 weeks of gestation. The criteria for hypertension in pregnancy are a systolic blood pressure of 140 mm Hg or higher or a diastolic blood pressure of 90 mm Hg or higher on two occasions at least 4 hours apart. If a pregnant client presents with elevated blood pressure, it is crucial for the nurse to initiate further evaluation for preeclampsia, as this condition can lead to serious complications for both the mother and the fetus.

Choice b reason:
Joint pain is not a typical sign of preeclampsia. While joint pain can be a symptom experienced during pregnancy due to various physiological changes, it is not specifically associated with preeclampsia and does not warrant further evaluation for this disorder on its own.

Choice c reason:
Vaginal discharge during pregnancy is common and can vary in consistency and amount. It is not a specific indicator of preeclampsia unless accompanied by other symptoms such as elevated blood pressure or proteinuria. Normal vaginal discharge is usually clear or milky white and does not indicate the need for preeclampsia evaluation.

Choice d reason:
Increased urine output is not typically associated with preeclampsia. In fact, preeclampsia can sometimes lead to reduced urine output due to kidney impairment. If a client has increased urine output, it may be due to other factors such as increased fluid intake or gestational diabetes.

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.
