A client who is 32 weeks gestation and has gestational diabetes calls the provider’s office to report decreased fetal movement over the last several hours. The provider advises her to report to OB triage for further testing.
What test should you anticipate the provider will order?
Non-stress test.
Contraction stress test.
Biophysical profile.
Ultrasound.
The Correct Answer is A
Choice A rationale
A non-stress test (NST) is a common test used to evaluate fetal well-being, especially in cases of decreased fetal movement. It measures the fetal heart rate in response to its movements. A reactive NST, where the fetal heart rate increases with movement, indicates good oxygenation and neurological function.
Choice B rationale
A contraction stress test (CST) evaluates the fetal heart rate response to uterine contractions, which can be induced by oxytocin or nipple stimulation. It is typically used to assess placental function and fetal tolerance to labor, not for initial assessment of decreased fetal movement.
Choice C rationale
A biophysical profile (BPP) combines an NST with ultrasound to assess fetal breathing, movement, tone, and amniotic fluid volume. While comprehensive, it is more time-consuming and usually reserved for further evaluation if the NST is non-reactive.
Choice D rationale
An ultrasound can assess fetal growth, amniotic fluid volume, and anatomical structures. However, it does not provide real-time information on fetal heart rate reactivity, making it less suitable for immediate assessment of decreased fetal movement.

Correct Answer is A
Explanation
Choice A rationale
The occiput anterior (OA) position is considered the optimal fetal position for vaginal birth. In this position, the baby’s head is down, and the back of the head (occiput) is facing the mother’s front. This position allows for the most efficient passage through the birth canal.
Choice B rationale
The occiput posterior (OP) position, where the baby’s head is down but facing the mother’s back, can lead to a longer and more painful labor. It is not considered optimal for vaginal birth.
Choice C rationale
Breech positions, where the baby’s buttocks or feet are positioned to come out first, are not optimal for vaginal birth and often require a cesarean section due to the increased risk of complications.
Choice D rationale
The transverse position, where the baby is lying sideways across the uterus, is not suitable for vaginal birth. This position typically requires a cesarean section to safely deliver the baby.
Correct Answer is A
Explanation
Choice A rationale
This statement is incorrect. Vagus nerve stimulation actually decreases FHR variability. The vagus nerve, part of the parasympathetic nervous system, slows the heart rate and reduces variability.
Choice B rationale
This statement is correct. Baroreceptors are sensors located in blood vessels that help regulate blood pressure by detecting changes in the stretch of the vessel walls. They play a crucial role in maintaining stable blood pressure levels.
Choice C rationale
This statement is correct. The autonomic nervous system, which includes the sympathetic and parasympathetic nervous systems, controls the fetal heart rate. It regulates the balance between heart rate acceleration and deceleration.
Choice D rationale
This statement is correct. Chemoreceptors respond to changes in blood gas levels, such as oxygen and carbon dioxide. They help regulate respiratory and cardiovascular responses to maintain homeostasis.
