Contraction Stress Test (CST)
Contraction Stress Test (CST) ( 5 Questions)
A client is scheduled for a Contraction Stress Test (CST).
When should the CST be performed?
A contraction stress test (CST) is performed near the end of pregnancy (34 weeks’ gestation) to determine how well the fetus will cope with the contractions of childbirth. The test triggers contractions and monitors the fetal heart rate using a cardiotocograph. A normal heartbeat is a good sign that the fetus will be healthy during labor.
Choice A is wrong because a CST is usually done after 32 weeks of gestation, not before 28 weeks. Doing the test too early may not be safe for the fetus.
Choice C is wrong because a CST is not only done for clients with diabetes mellitus. It may be done for clients who have complications during their pregnancy or who have abnormal results from other tests, such as a nonstress test or a biophysical profile.
Choice D is wrong because a CST is not only done for clients with hypertension. It may be done for clients who have complications during their pregnancy or who have abnormal results from other tests, such as a nonstress test or a biophysical profile.
