A nurse is reinforcing teaching with a client who is pregnant and has a prescription for Rho(D) immune globulin. Which of the following information should the nurse include?
This medication destroys Rh antibodies in a newborn who is Rh-positive.
This medication destroys Rh antibodies in a woman who is Rh-negative.
This medication prevents the formation of Rh antibodies by a woman who is Rh-negative.
This medication prevents the formation of RH antibodies in a newborn who is Rh-positive.
The Correct Answer is C
Choice A rationale:
This statement is incorrect because Rho(D) immune globulin does not destroy Rh antibodies in a newborn who is Rh-positive. Instead, it acts to prevent the development of Rh antibodies in the mother.
Choice B rationale:
This statement is also incorrect. Rho(D) immune globulin does not destroy Rh antibodies in a woman who is Rh-negative. It is given to Rh-negative women to prevent them from forming Rh antibodies in response to Rh-positive fetal blood during pregnancy.
Choice C rationale:
This is the correct choice. Rho(D) immune globulin is given to Rh-negative women to prevent the formation of Rh antibodies. If an Rh-negative woman is exposed to Rh-positive blood (usually during childbirth), her immune system may recognize the Rh antigen as foreign and start producing Rh antibodies. These antibodies could potentially cross the placenta during a subsequent pregnancy and attack the red blood cells of an Rh-positive fetus, causing hemolytic disease in the newborn. Rho(D) immune globulin helps prevent this sensitization process.
Choice D rationale:
This statement is incorrect. Rho(D) immune globulin does not prevent the formation of Rh antibodies in a newborn who is Rh-positive. Its main purpose is to protect Rh-negative women from forming antibodies that could harm future Rh-positive pregnancies.

Correct Answer is B
Explanation
Choice A reason:
Initiating epidural anesthesia too soon may delay rupture of fetal membranes. This statement is not accurate. Epidural anesthesia itself does not have a direct impact on the rupture of fetal membranes. The timing of rupturing membranes is determined based on the progress of labor and other clinical indications. There is no causal relationship between epidural anesthesia and the timing of membrane rupture.
Choice B reason:
Initiating epidural anesthesia too soon can prolong labor. This statement is correct. Epidural anesthesia, while providing pain relief during labor, can also cause some degree of motor blockage and decrease the woman's ability to push effectively. This can potentially lead to a lengthening of the labor process. It is generally recommended to wait until a good labor pattern has been established to avoid unnecessary prolongation of labor.
Choice C reason:
Initiating epidural anesthesia too soon can cause fetal depression. This statement is not entirely accurate. Epidural anesthesia can cross the placenta and reach the fetus, but the effect on the baby is usually minimal. However, fetal monitoring is essential during labor to ensure the baby's well-being, regardless of whether epidural anesthesia is used or not.
Choice D reason:
Initiating epidural anesthesia too soon can cause maternal hypertension. This statement is not supported by evidence. Epidural anesthesia does not typically cause maternal hypertension. It can, however, lead to a decrease in blood pressure in some cases, which is why careful monitoring of maternal blood pressure is necessary during and after the administration of epidural anesthesia.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should include teaching the client to perform daily fetal movement counts because it is an essential aspect of monitoring the baby's well-being and assessing fetal distress. Fetal movement counts help the client become familiar with their baby's normal patterns of movement, allowing them to detect any changes or decreased movements promptly. This can be crucial in identifying potential issues with the baby's health and seeking timely medical attention.
Choice B rationale:
The nurse should not advise limiting fluid intake to 1,000 mL/day for a client with mild preeclampsia. Adequate hydration is important during pregnancy, and excessive fluid restriction can lead to dehydration, which is harmful to both the mother and the baby. Preeclampsia can cause fluid retention and high blood pressure, but complete fluid restriction is not the appropriate approach for managing the condition.
Choice C rationale:
The nurse should not suggest limiting sodium intake to 2,000 mg/day for a client with mild preeclampsia. While reducing sodium intake can be beneficial for some individuals with hypertension, it is not the primary focus in managing mild preeclampsia. The mainstay of treatment for mild preeclampsia typically involves close monitoring, rest, and potential medications to control blood pressure if necessary.
Choice D rationale:
The nurse should not recommend that the client rest in bed in the supine position. During pregnancy, especially with preeclampsia, lying flat on the back (supine position) can lead to a condition called supine hypotensive syndrome. This occurs when the weight of the uterus presses on the vena cava, reducing blood flow back to the heart and potentially causing a drop in blood pressure and decreased blood flow to the baby.
