A nurse is performing a contraction stress test (CST) on a client who is at 40 weeks of gestation. The results of the test indicate a negative CST. Which of the following actions should the nurse take?

Choice A rationale A negative contraction stress test (CST) indicates that the fetus tolerates uterine contractions well, with no evidence of late decelerations, implying adequate uteroplacental function. Repeating the test in 20 minutes is unnecessary as a negative result signifies fetal well-being and is a favorable outcome. Choice B rationale Administering an intravenous fluid bolus is often used in situations like non-reassuring fetal heart rate patterns or to improve uteroplacental perfusion, such as during a non-reactive non-stress test or before an oxytocin challenge. A negative CST indicates a healthy fetus, so a fluid bolus is not indicated. Choice C rationale Preparing for a cesarean birth is indicated when there is evidence of fetal distress or a high risk of adverse outcomes, such as with a positive CST (late decelerations present). A negative CST indicates a reassuring fetal status, making a cesarean birth unnecessary based solely on these test results. Choice D rationale A negative CST indicates a healthy fetus with good uteroplacental reserve, suggesting that the fetus will likely tolerate the stress of labor. Therefore, allowing the labor to progress naturally is the appropriate action, as there are no indications of fetal compromise.
