When is it most important for the nurse to assess a pregnant client's deep tendon reflexes (DTRs)?

Choice B is correct because assessing the DTRs of a pregnant client with an elevated blood pressure can help detect signs of preeclampsia, a serious complication of pregnancy that can cause seizures, organ damage, and fetal death. Preeclampsia can cause hyperreflexia, which is an exaggerated response of the DTRs.

Choice A is incorrect because ankle edema is not a reliable indicator of preeclampsia and does not require assessing the DTRs. Ankle edema is a common finding in normal pregnancy due to increased blood volume and fluid retention.

Choice C is incorrect because assessing the DTRs during admission to labor and delivery is not as important as assessing them if the client has an elevated blood pressure. Assessing the DTRs during admission to labor and delivery can help monitor the client's neurological status, but it is not a priority action.

Choice D is incorrect because assessing the DTRs within the first trimester of pregnancy is not as important as assessing them if the client has an elevated blood pressure. Assessing the DTRs within the first trimester of pregnancy can help establish a baseline, but it is not a priority action.

Choice A reason: Providing pain medication to increase the client's tolerance of labor pains is not a specific intervention for the second stage of labor. Pain medication is a drug that relieves pain by blocking pain signals or reducing inflammation. Pain medication can be given during any stage of labor, depending on the client's preference and condition. However, pain medication may have side effects such as sedation, nausea, or respiratory depression, and may affect the fetal heart rate or the progress of labor.

Choice B reason: Assessing the fetal heart rate and pattern for signs of fetal distress is not a particular intervention for the second stage of labor. Fetal heart rate and pattern are indicators of fetal well-being and oxygenation. Fetal heart rate and pattern should be monitored throughout labor, especially during contractions, to detect any abnormalities or complications such as bradycardia, tachycardia, or decelerations.

Choice D reason: Monitoring effects of oxytocin administration to help achieve cervical dilation is not a relevant intervention for the second stage of labor. Oxytocin is a hormone that stimulates uterine contractions and cervical dilation. Oxytocin can be administered during labor to augment or induce labor, especially if there is prolonged or dysfunctional labor. However, oxytocin is not needed in the second stage of labor, when the cervix is already fully dilated and the focus is on pushing and delivering the baby.
