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 D
Explanation
Choice A rationale
Preparing to administer a prescribed oxytocic preparation is a possible intervention for postpartum hemorrhage, but the immediate first step should be to assess the uterus, the most common source of early postpartum bleeding.
Choice B rationale
Assessing the client's blood pressure is important in evaluating the extent of blood loss, but it is not the initial action to take. Addressing the likely cause of the bleeding should precede further assessment of vital signs.
Choice C rationale
Assessing the bladder for distention is important as a full bladder can displace the uterus and interfere with its contraction, potentially contributing to bleeding. However, directly addressing the uterine tone is the immediate first step.
Choice D rationale
Massaging the client's fundus is the priority action because uterine atony, a soft and non-contracted uterus, is the most frequent cause of early postpartum hemorrhage. Stimulating the uterus to contract by massage helps to compress the blood vessels at the placental site and decrease bleeding. .
Correct Answer is A
Explanation
Choice A rationale
A reactive nonstress test demonstrates at least two accelerations in fetal heart rate, defined as an increase of 15 beats per minute above the baseline lasting for 15 seconds, within a 20-minute period. These accelerations indicate adequate fetal oxygenation and a healthy fetal autonomic nervous system response to movement.
Choice B rationale
Drawing blood to evaluate the baby's risk of genetic problems is typically performed through procedures like amniocentesis or chorionic villus sampling, not during a nonstress test. A nonstress test assesses fetal well-being based on heart rate patterns in response to fetal movement.
Choice C rationale
While fetal movement is an indicator of fetal well-being, the nonstress test specifically evaluates the fetal heart rate response to that movement. The number of movements within a specific time frame is a component of a biophysical profile, not the sole indicator in a nonstress test.
Choice D rationale
Ultrasound is used to visualize fetal anatomy and assess for congenital anomalies, which is a component of a fetal anatomy scan typically performed around 18-20 weeks of gestation. A nonstress test primarily monitors fetal heart rate and its reactivity.
