A nurse is educating a pregnant client about the Non-Stress Test (NST).

Which statement by the client indicates understanding of the test?

"NST is performed after 28 weeks of gestation or earlier if there are risk factors.".

"A nonreactive NST means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period.".

. "NST requires placing two belts with sensors on my abdomen: one to monitor the fetal heart rate and one to monitor the uterine contractions.".

"A reactive NST may indicate fetal hypoxia, distress, sleep, medication effect, or neurological abnormality.".

Answer and Explanation

The Correct Answer is A

"NST is performed after 28 weeks of gestation or earlier if there are risk factors."12 This statement indicates that the client understands when and why an NST is done.

Choice B is wrong because it describes a reactive NST, not a nonreactive one.

A reactive NST means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period.2

Choice C is wrong because it confuses NST with contraction stress test (CST), which requires monitoring uterine contractions.

NST does not involve contractions.2

Choice D is wrong because it describes possible causes of a nonreactive NST, not a reactive one.

A nonreactive NST may indicate fetal hypoxia, distress, sleep, medication effect, or neurological abnormality.2

Correct Answer is A

Explanation

“I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.” This statement indicates the client understands the test procedure of a CST, which is a test that triggers contractions and registers how the baby’s heart reacts.

The test is done by placing two sensor belts around the abdomen, one to measure the baby’s heartbeat and the other to measure contractions.

The client may receive oxytocin through an IV to induce contractions.

Choice B is wrong because the client does not need to fast for 24 hours before the test.

There is no evidence that fasting is required for a CST.

Choice C is wrong because the client will not be sedated during the test.

Sedation is not necessary for a CST and may interfere with the results.

Choice D is wrong because the client does not need to drink plenty of fluids before the test.

There is no evidence that drinking fluids is required for a CST.

A. Cord compression B. Fetal hypoxia C. Normal placental function D. Adequate fetal oxygenation

Correct Answer is A

Explanation

This finding indicates that the umbilical cord is being compressed, which can reduce the blood flow and oxygen supply to the fetus.

Variable decelerations are abrupt decreases in the fetal heart rate (FHR) that vary in shape, duration, and degree of fall below the baseline.

They are seen as W- or U-shaped waves on the monitor.

Choice B is wrong because fetal hypoxia is not indicated by variable decelerations, but by late decelerations, which are gradual decreases in the FHR that begin after the peak of the contraction and return to baseline after the contraction ends.

Late decelerations are associated with uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen to the fetus.

Choice C is wrong because normal placental function is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability (6 to 25 beats per minute) and accelerations (increases in the FHR above the baseline).

Normal placental function ensures adequate fetal oxygenation and well-being.

Choice D is wrong because adequate fetal oxygenation is not indicated by variable decelerations, but by reassuring FHR patterns, such as moderate variability and accelerations.

Adequate fetal oxygenation means that the fetus is not experiencing hypoxia or distress.

Normal ranges for FHR are 110 to 160 beats per minute at term and 120 to 160 beats per minute before term.

Normal ranges for uterine contractions are 2 to 5 contractions in 10 minutes, lasting less than 90 seconds each.
