A nurse is caring for a client at term in labor.
The client states, “I can’t do this anymore.”. She reports rectal pressure and increasing nausea. SVE (sterile vaginal exam) performed: 9 cm, 100% effaced, +1 station.
Encourage the client to continue pushing.
Prepare the client for delivery.
Administer pain relief as prescribed.
Reassure the client and provide emotional support.
The Correct Answer is B
Choice A rationale
Encouraging the client to continue pushing is not appropriate at this stage. The client is 9 cm dilated, which indicates that she is in the transition phase of labor, not yet fully dilated and ready to push. Pushing at this stage could cause cervical swelling and delay progress.
Choice B rationale
Preparing the client for delivery is the most appropriate action. The client is in the transition phase of labor, with 9 cm dilation, 100% effacement, and +1 station. This indicates that delivery is imminent, and the nurse should prepare for the birth process.
Choice C rationale
Administering pain relief as prescribed may be considered, but it is not the priority action at this stage. The client is in the transition phase, and administering pain relief could interfere with the natural progression of labor. Non-pharmacological support may be more appropriate.
Choice D rationale
Reassuring the client and providing emotional support is important, but it is not the primary action at this stage. The nurse should focus on preparing for delivery while also providing support and reassurance.

Correct Answer is A
Explanation
Choice A rationale
Terbutaline is a beta-adrenergic agonist that works by relaxing the smooth muscles of the uterus, thereby reducing uterine contractions. It is commonly used in cases of tachysystole and recurrent late decelerations to decrease uterine activity and improve fetal oxygenation. Terbutaline’s mechanism of action involves stimulating beta-2 adrenergic receptors, which leads to an increase in cyclic AMP and subsequent relaxation of uterine smooth muscle.
Choice B rationale
Oxytocin is a hormone that stimulates uterine contractions and is typically used to induce or augment labor. Administering oxytocin in a situation where there is already tachysystole and recurrent late decelerations would exacerbate the problem by increasing uterine contractions, potentially leading to further fetal distress.
Choice C rationale
Misoprostol is a prostaglandin analog used to ripen the cervix and induce labor. Similar to oxytocin, it would not be appropriate in this scenario as it would increase uterine contractions, worsening the tachysystole and late decelerations.
Choice D rationale
Magnesium sulfate is primarily used as a tocolytic to prevent preterm labor and as a neuroprotective agent for the fetus in cases of preeclampsia. While it has some uterine relaxation properties, it is not the first-line treatment for reducing uterine activity in the context of tachysystole and late decelerations.
Correct Answer is A
Explanation
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.
