Non-Stress Test (NST)
Non-Stress Test (NST) ( 5 Questions)
A pregnant client asks the nurse how long the Non-Stress Test (NST) is usually performed.
How should the nurse respond ?
The NST is usually done for 20 to 40 minutes or until at least two fetal movements are recorded. This is because the NST monitors the fetal heart rate in response to fetal movement, in order to assess fetal well-being. A reactive test indicates that the fetal heart rate accelerates by 15 bpm above the baseline and lasts for 15 to 30 seconds in association with fetal movement.
It does not answer the question of how long the NST is usually performed. It only states when the NST is usually performed, which is after 28 weeks of gestation or earlier if there are risk factors.
It does not answer the question of how long the NST is usually performed. It only describes how the NST is performed, which is by placing two belts with sensors on the client’s abdomen.
It does not answer the question of how long the NST is usually performed. It only explains how the NST is interpreted, which is as reactive or nonreactive.
