A nurse is performing a non-stress test (NST) for a client who is 34 weeks pregnant and has pre-eclampsia.
Which of the following fetal heart rate patterns indicates a reactive test?
Two or more accelerations of at least 15 beats/min above baseline lasting for at least 15 seconds in a 20-minute period
No accelerations or decelerations in a 20-minute period
One acceleration of at least 10 beats/min above baseline lasting for at least 10 seconds in a 20-minute period
Variable decelerations with normal variability in a 20-minute period
The Correct Answer is A
Two or more accelerations of at least 15 beats/min above baseline lasting for at least 15 seconds in a 20-minute period. This indicates a reactive test, which means that the fetus is well oxygenated and not in distress.
Choice B is wrong because no accelerations or decelerations in a 20-minute period indicate a non-reactive test, which may suggest fetal hypoxia or acidosis.
Choice C is wrong because one acceleration of at least 10 beats/min above baseline lasting for at least 10 seconds in a 20-minute period is the criterion for a reactive test for gestational age less than 32 weeks, not 34 weeks.
Choice D is wrong because variable decelerations with normal variability in a 20-minute period indicate cord compression or fetal head compression, not a reactive test.

Protein excretion of 450 mg indicates proteinuria.Proteinuria is the presence of excess protein in the urine, which can be a sign of kidney damage or disease.Normal protein excretion in a 24-hour urine collection is less than 150 mg.
Choice A is wrong because protein excretion of 150 mg is within the normal range.
Choice B is wrong because protein excretion of 250 mg is slightly above the normal range, but not enough to indicate proteinuria.
Choice C is wrong because protein excretion of 350 mg is also above the normal range, but not enough to indicate proteinuria.
Preeclampsia is a condition that affects some pregnant women, usually after 20 weeks of pregnancy.It causes high blood pressure and proteinuria, which can harm both the mother and the baby.A 24-hour urine collection is a simple lab test that measures what’s in the urine and checks kidney function.The test is done by collecting all the urine passed in a 24-hour period in a special container that must be kept cool until returned to the lab.
