Non-Stress Test (NST)
Non-Stress Test (NST) ( 5 Questions)
A nurse is performing a nonstress test on a pregnant client who is at 32 weeks’ gestation and has diabetes mellitus type I.
Which finding indicates that the test is reactive?
Fetal heart rate (FHR) increases by at least 15 beats/min for at least 15 seconds twice or more in a 20-minute period. This indicates that the test is reactive, which means the baby is healthy and getting enough oxygen.
FHR decreases by at least 15 beats/min for at least 15 seconds twice or more in a 20-minute period. This indicates a deceleration, which may be a sign of fetal distress.
FHR remains stable throughout the test. This indicates that the test is nonreactive, which means the baby’s heartbeat didn’t change when moving, or the baby wasn’t moving much. A
FHR increases by less than 10 beats/min for less than 10 seconds twice or more in a 20-minute period. This indicates that the test is nonreactive, which means the baby’s heart rate did not increase enough to meet the criteria for a reactive test.
Fetal heart rate (FHR) increases by at least 15 beats/min for at least 15 seconds twice or more in a 20-minute period. This indicates that the test is reactive, which means the baby is healthy and getting enough oxygen.
Choice B is wrong because FHR decreases by at least 15 beats/min for at least 15 seconds twice or more in a 20-minute period.
This indicates a deceleration, which may be a sign of fetal distress.
Choice C is wrong because FHR remains stable throughout the test.
This indicates that the test is nonreactive, which means the baby’s heartbeat didn’t change when moving, or the baby wasn’t moving much. A nonreactive result doesn’t always mean your baby has a health problem, but it can mean more tests may be necessary.
Choice D is wrong because FHR increases by less than 10 beats/min for less than 10 seconds twice or more in a 20-minute period. This indicates that the test is nonreactive, which means the baby’s heart rate did not increase enough to meet the criteria for a reactive test.
