A primigravida at 40 weeks of gestation is having erratic uterine contractions every 5 to 10 minutes and states that they are very painful.
Her cervix is dilated 2 cm and has not changed in 3 hours.
The woman is crying and wants an epidural.
What is the likely status of this woman's labor?
She is exhibiting hypotonic uterine dysfunction.
She is experiencing a normal latent stage.
She is exhibiting hypertonic uterine dysfunction.
She is experiencing precipitous labor.
The Correct Answer is B
Choice A rationale
Hypotonic uterine dysfunction typically occurs in the active phase of labor (after 4 cm cervical dilation) and is characterized by weak, infrequent, and ineffective contractions that do not lead to cervical change. The client in the latent phase with slow cervical change is not yet in the active phase.
Choice B rationale
The latent phase of the first stage of labor is characterized by irregular, mild to moderate contractions that cause slow, gradual cervical dilation and effacement. It can be lengthy, especially in primigravidas, and the discomfort can be significant. A cervical dilation of 2 cm with no change in 3 hours in the presence of painful, erratic contractions every 5 to 10 minutes aligns with a normal latent phase.
Choice C rationale
Hypertonic uterine dysfunction usually occurs in the latent phase and is characterized by frequent, uncoordinated, and strong contractions that are ineffective in causing cervical dilation or effacement. While the contractions are painful, they are not described as excessively strong or uncoordinated, and the client is in the expected early stage of labor.
Choice D rationale
Precipitous labor is a very rapid labor and delivery, typically lasting less than 3 hours from the onset of regular contractions to expulsion of the fetus. The client's labor is progressing slowly, with minimal cervical change over 3 hours, which is the opposite of precipitous labor.

Correct Answer is A
Explanation
Choice A rationale
When the fetal heart tones are heard loudest in the upper right abdominal quadrant above the umbilicus, it suggests that the fetal back, which transmits sound most clearly, is located in that area. In a breech presentation, the fetal buttocks or feet are in the lower uterine segment, and the head is in the upper portion of the uterus. Therefore, the fetal heart sounds would be best auscultated in the upper abdomen.
Choice B rationale
In the left occiput anterior (LOA) position, the fetal occiput is in the left anterior quadrant of the maternal pelvis. The fetal heart tones are typically heard loudest in the lower left quadrant of the maternal abdomen because the fetal back is usually anterior and slightly to the left.
Choice C rationale
Polyhydramnios is an excessive amount of amniotic fluid. While it can sometimes make it more difficult to auscultate fetal heart tones clearly due to increased fluid volume, it does not directly correlate with the location where the heart tones are heard loudest. The position of the fetus is the primary determinant of the auscultation location.
Choice D rationale
In the right occiput posterior (ROP) position, the fetal occiput is in the right posterior quadrant of the maternal pelvis. The fetal heart tones would typically be heard loudest in the lower right quadrant of the maternal abdomen, as the fetal back would be positioned posteriorly and to the right.
Correct Answer is B
Explanation
Choice A rationale
Supine positioning can compress the vena cava, leading to decreased venous return, reduced cardiac output, and potential maternal hypotension, which can compromise fetal oxygenation. Alternative positions like lateral or semi-recumbent are generally preferred during labor to optimize blood flow.
Choice B rationale
Assessing anesthesia or pain level every 30 minutes is crucial in the active phase of labor to evaluate the effectiveness of pain management interventions and the client's comfort. This frequent monitoring allows for timely adjustments to the pain management plan based on the client's subjective experience and physiological responses.
Choice C rationale
While assessing vaginal bleeding and the fundus is important in the postpartum period to monitor for uterine involution and hemorrhage, it is not the priority during the active phase of labor. The focus during active labor is on maternal and fetal well-being during the labor process itself.
Choice D rationale
Continuous or intermittent oxygen saturation monitoring may be indicated based on the client's condition and fetal heart rate patterns, but it is not a routine assessment every half hour for all clients in active labor. It is typically reserved for situations of suspected maternal hypoxemia or fetal distress.
