A nurse is admitting a client who is at 39 weeks of gestation and who states, "My water broke on the way to the hospital.”. Which of the following actions should the nurse take first?

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.

Choice A rationale

The vacuum cup for an assisted birth is strategically placed on the fetal occiput, which is the posterior aspect of the fetal skull, not in front of the fetal ears. Proper placement over the posterior fontanelle promotes traction directly on the bone, minimizing the risk of fetal scalp injury and ensuring efficient rotation and descent of the fetal head during traction. Positioning near the ears is incorrect and dangerous.

Choice B rationale

During a vacuum-assisted birth, the client is actively encouraged to push effectively with each uterine contraction, as the vacuum traction is applied only during a contraction. Maternal pushing augments the force of the vacuum device and facilitates the fetal head's descent through the birth canal, maximizing the procedure's success while minimizing the duration and number of pulls required for delivery.

Choice C rationale

Continuous fetal monitoring is absolutely essential throughout a vacuum-assisted birth procedure. It allows the nurse and provider to immediately assess the fetal heart rate (FHR) response to the procedure, identify potential complications like bradycardia or non-reassuring FHR patterns, and guide the discontinuation of the vacuum if fetal compromise is detected.

Choice D rationale

Administering a fluid bolus to ensure a full bladder is contraindicated during labor and birth. An empty bladder is preferred for fetal descent and to prevent obstruction of the birth canal. Furthermore, a full bladder can potentially be damaged by the descending fetal head, making bladder emptying (catheterization) common prior to assisted delivery if necessary.
