A nurse is interpreting the results of a contraction stress test (CST) for a client who is at 38 weeks of gestation.

The nurse notes that there are no late or significant variable decelerations of the fetal heart rate (FHR).

How should the nurse document this finding?

Positive CST

Negative CST

Unsatisfactory CST

Suspicious CST

Answer and Explanation

The Correct Answer is B

Negative CST. A negative CST means that the fetal heart rate does not slow down (decelerate) after a contraction, which indicates that the baby can tolerate the stress of labor.

This is a normal and reassuring result.

Choice A is wrong because a positive CST means that the fetal heart rate slows down and stays slow after more than half of the contractions, which indicates that the baby may be at risk for problems during labor.

This is an abnormal and concerning result.

Choice C is wrong because an unsatisfactory CST means that there are not enough contractions to produce a reliable result.

This may happen if the medication or nipple stimulation does not induce enough contractions, or if there are other factors that interfere with the test, such as maternal movement or fetal sleep.

Choice D is wrong because a suspicious CST means that the results are unclear or inconsistent. This may happen if the fetal heart rate slows down after some but not all of the contractions, or if there are other types of decelerations that are not clearly related to the contractions.

A suspicious CST may need to be repeated in a couple of days.

Correct Answer is B

Explanation

Negative CST.A negative CST means that there are no late or significant variable decelerations of the fetal heart rate (FHR) during three uterine contractions in 10 minutes.

This indicates that the fetus is well oxygenated and can tolerate the stress of labor contractions.

Choice A is wrong because a positive CST means that there are late decelerations of the FHR with 50% or more of the contractions.

This suggests that the fetus is at risk of hypoxia and may need early delivery.

Choice C is wrong because an unsatisfactory CST means that there are fewer than three contractions in 10 minutes or the tracing is not interpretable.

This does not provide enough information to assess the fetal well-being.

Choice D is wrong because an equivocal CST means that there are either intermittent late decelerations or significant variable decelerations.

This indicates that the fetus may have some degree of compromise and may need further testing.

Normal ranges for FHR are 110 to 160 beats per minute, and for uterine contractions are 2 to 5 per 10 minutes.

A. Prepare the client for an amnioinfusion B. Apply an internal fetal scalp electrode C. Administer IV fluid bolus to the client D. Discontinue oxytocin infusion if present

Correct Answer is A

Explanation

Prepare the client for an amnioinfusion.An amnioinfusion is a procedure that adds fluid to the uterus during labor to relieve cord compression and improve fetal condition.Variable decelerations on the fetal monitor tracing are a sign of cord compression and fetal distress.If repositioning and oxygen administration do not resolve the decelerations, an amnioinfusion may be indicated.

Choice B is wrong because applying an internal fetal scalp electrode does not address the cause of variable decelerations, which is cord compression.

An internal fetal scalp electrode is used to monitor the fetal heart rate more accurately, but it does not improve fetal oxygenation or prevent cord compression.

Choice C is wrong because administering IV fluid bolus to the client may help increase maternal blood volume and placental perfusion, but it does not directly increase amniotic fluid volume or relieve cord compression.

Choice D is wrong because discontinuing oxytocin infusion if present may reduce uterine contractions and decrease cord compression, but it may also prolong labor and increase the risk of infection or fetal compromise.Oxytocin infusion should only be discontinued if there are signs of uterine hyperstimulation or fetal intolerance.

A nurse is caring for a client who is pregnant and undergoing a contraction stress test (CST). The nurse observes three uterine contractions in 10 minutes, with no late or significant variable decelerations of the fetal heart rate (FHR). How should the nurse interpret this finding?

Correct Answer is B

Explanation

Correct Answer is A

Explanation

(Select all that apply) A nurse is performing a nonstress test (NST) for a client who is at 32 weeks of gestation and has gestational diabetes mellitus. The nurse uses vibroacoustic stimulation to elicit fetal movement and acceleration of FHR. What are the indications for using this method?

A nurse is reviewing the findings of a biophysical profile (BPP) for a client who is at 40 weeks of gestation. The BPP score is 6 out of 10 points. Which of the following components are included in this score? (Select all that apply.)

A nurse is using vibroacoustic stimulation (VAS) to stimulate fetal movement during a nonstress test (NST). What action should the nurse take when applying VAS?

A nurse is assessing a fetal heart rate (FHR) tracing for a client who is in active labor. The nurse notes that the baseline FHR is 150 bpm with absent variability and recurrent variable decelerations with slow return to baseline. What category of FHR tracing does this represent?

A nurse is caring for a client who is undergoing an oxytocin-stimulated contraction stress test (CST). The nurse observes three contractions in 10 minutes with no late decelerations of the fetal heart rate (FHR). Which of the following actions should the nurse take?

A nurse is caring for a client who is scheduled for an amniocentesis at 35 weeks of gestation to assess fetal lung maturity. Which of the following laboratory tests will provide this information?

A nurse is providing discharge instructions to a client who had a nonreactive nonstress test (NST) followed by a biophysical profile (BPP) with a score of 8/10. Which of the following statements by the client indicates an understanding of the teaching?
