A nurse is preparing a client for a Contraction Stress Test (CST).

Which method can be used to induce uterine contractions during the test?

Nipple stimulation.

Intravenous oxytocin infusion.

Administering oral medications.

Applying warm compresses to the abdomen.

Answer and Explanation

The Correct Answer is B

This method can be used to induce uterine contractions during the test by stimulating the uterus with a hormone that causes contractions.

Oxytocin is also the hormone that naturally triggers labor contractions.

Choice A is wrong because nipple stimulation can also induce contractions, but it is not as reliable or controllable as oxytocin infusion.

Choice C is wrong because oral medications are not used to induce contractions during a CST.

Some medications may interfere with the test results or cause side effects.

Choice D is wrong because applying warm compresses to the abdomen does not induce contractions.

It may help with pain relief or relaxation, but it does not affect the uterus.

Normal ranges for uterine contractions during a CST are three contractions in 10 minutes, each lasting 40 to 60 seconds.

Normal ranges for fetal heart rate during a CST are 110 to 160 beats per minute, with no decelerations after contractions.

Correct Answer is B

Explanation

Choice A is wrong because it describes a transabdominal CVS procedure, which involves a needle instead of a catheter.

Choice C is wrong because it describes a procedure that is not used for CVS.A needle inserted through the cervix could damage the fetal membranes or cause bleeding.

Choice D is wrong because it describes a procedure that is not possible.A catheter cannot be inserted through the abdomen and uterus into the placenta.

Normal ranges for CVS are not applicable as it is a diagnostic test, not a screening test.

It provides a definitive result of whether the fetus has a chromosomal abnormality or a genetic disorder.CVS is usually done between 10 and 13+6 weeks of pregnancy.

A. The velocity of blood flow in the uterine and fetal vessels. B. The amount of amniotic fluid in the uterine cavity. C. The pressure of blood flow in the umbilical cord. D. The oxygen saturation level of fetal blo.

Correct Answer is A

Explanation

A Doppler ultrasound blood flow analysis measures the velocity of blood flow in the uterine and fetal vessels.

This test can help assess the fetal well-being and oxygenation in cases of intrauterine growth restriction (IUGR).

Choice B is wrong because the amount of amniotic fluid in the uterine cavity is measured by ultrasound, not Doppler.

Choice C is wrong because the pressure of blood flow in the umbilical cord is not directly measured by Doppler, but rather inferred from the resistance index or pulsatility index.

Choice D is wrong because the oxygen saturation level of fetal blood is not measured by Doppler, but rather by fetal scalp sampling or pulse oximetry.
