A nurse is caring for a client in labor who is experiencing incomplete uterine relaxation between hypertonic contractions.

What adverse effect does the nurse recognize as a result of this contraction pattern?

Choice A rationale
While inserting an IV catheter can be a part of the overall management plan for a client showing late decelerations on the electronic fetal monitor, it is not the initial course of action. The primary concern with late decelerations is that they may indicate fetal hypoxia, and the first response should be aimed at improving fetal oxygenation.
Choice B rationale
Assisting the client into the left-lateral position is the correct initial response when late decelerations are observed on the electronic fetal monitor. This position helps to maximize blood flow to the uterus and placenta, thereby improving oxygen delivery to the fetus.
Choice C rationale
Applying a fetal scalp electrode may be useful for obtaining a more accurate fetal heart rate tracing, but it is not the initial response to late decelerations. The priority is to address the potential fetal hypoxia that late decelerations may indicate.
Choice D rationale
Performing a vaginal exam would not be the initial response to late decelerations. While a vaginal exam can provide valuable information about the progress of labor, it does not address the issue of potential fetal hypoxia indicated by late decelerations.

Choice D rationale
The client is experiencing the first stage, latent phase of labor. This phase is characterized by contractions that are typically mild and irregular, occurring every 5-30 minutes and lasting about 30-45 seconds. The cervix dilates from 0 to 3 cm and effaces from 0% to 40%. The fetus descends into the pelvis, but is not yet engaged. The client may feel excited and anxious as labor begins.
Choice A rationale
The first stage, active phase of labor is characterized by regular, strong contractions occurring every 3-5 minutes and lasting about 40-70 seconds. The cervix dilates from 4 to 7 cm and effaces from 40% to 100%. The fetus descends and engages in the pelvis. The client may feel increased discomfort and a strong urge to bear down.
Choice B rationale
The first stage, transition phase of labor is characterized by intense contractions occurring every 2-3 minutes and lasting about 45-90 seconds. The cervix dilates from 8 to 10 cm and effaces from 100%. The fetus descends and engages in the pelvis. The client may feel overwhelmed, restless, and irritable.
Choice C rationale
The second stage of labor begins when the cervix is fully dilated and ends with the delivery of the baby. The contractions are strong, occurring every 2-3 minutes and lasting about 45-90 seconds. The client feels a strong urge to push during contractions.
