Contraction Stress Test (CST)
Contraction Stress Test (CST) ( 5 Questions)
A nurse is preparing a pregnant client for a Contraction Stress Test (CST).
What is the purpose of inducing uterine contractions during the test?
The purpose of inducing uterine contractions during the test is to simulate labor contractions and check how the baby’s heart rate reacts to the stress of reduced blood and oxygen supply. A normal heart rate indicates that the baby will be healthy during labor.
Monitoring the FHR is not the purpose of the test, but a means to assess fetal well-being.
Achieving at least three contractions lasting 40 to 60 seconds is not the purpose of the test, but a criterion for a satisfactory test.
Identifying fetal hypoxia or distress is not the purpose of the test, but a possible outcome of an abnormal test.

Choice B is wrong because monitoring the FHR is not the purpose of the test, but a means to assess fetal well-being.
Choice C is wrong because achieving at least three contractions lasting 40 to 60 seconds is not the purpose of the test, but a criterion for a satisfactory test.
