A nurse is caring for a client who is in active labor and requesting an epidural. Which of the following actions should the nurse take?

Choice A rationale Delaying the epidural until the client reaches a specific dilation, such as 7 cm, is not based on current standards of pain management; an epidural can be administered at any time during active labor, as long as the client desires it and there are no contraindications. Labor progress is often enhanced, not hindered, by effective pain relief, which reduces catecholamine release and subsequent uterine vasoconstriction, promoting efficient uterine contractions. The decision to administer an epidural is primarily based on maternal request and clinical assessment. Choice B rationale Placing the client in a supine position (lying flat on the back) before epidural placement or during labor is contraindicated because the gravid uterus can compress the vena cava and aorta, reducing venous return and subsequently decreasing cardiac output and uteroplacental perfusion. This supine hypotension syndrome can lead to fetal distress. The client should be positioned on their side or sitting upright with feet supported, or with a wedge under the hip to maintain lateral tilt. Choice C rationale Administering an intravenous fluid bolus, typically 500 to 1000 mL of an isotonic solution like Lactated Ringer's or 0.9% Sodium Chloride, is a standard prophylactic measure before epidural anesthesia. This fluid load expands the intravascular volume, which helps to mitigate the common side effect of hypotension caused by the sympathetic blockade resulting from the anesthetic agents diffusing into the epidural space and causing peripheral vasodilation. Choice D rationale Ondansetron is an antiemetic used to prevent nausea and vomiting, which can sometimes occur with labor or as a side effect of opioid use or hypotension associated with epidural placement. However, it is not the primary or most immediate action before an epidural, nor is it a universal prophylactic requirement. The priority before an epidural is the IV fluid bolus to prevent hypotension, which poses a greater immediate risk to the mother and fetus.
