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 A

Explanation

The test involves an ultrasound and a nonstress test.

A biophysical profile (BPP) is a way to check on the overall fetal health by observing the fetus’s heart rate, breathing, movement, muscle tone, and the amount of amniotic fluid surrounding the fetus in the uterus.

It is typically performed after 28 weeks of pregnancy, especially for high-risk pregnancies or if there is a chance of complications.

Choice B is wrong because a contraction stress test is not part of a BPP.

A contraction stress test measures how the fetus’s heart rate changes during contractions induced by oxytocin or nipple stimulation.

It is a different test from a nonstress test, which measures the fetus’s heart rate while moving and at rest without any stimulation.

Choice C is wrong because a Doppler ultrasound is not part of a BPP.

A Doppler ultrasound uses sound waves to measure the blood flow in the umbilical cord and other blood vessels.

It is a different type of ultrasound from the one used in a BPP, which uses sound waves to create images of the fetus and the amniotic fluid.

Choice D is wrong because it combines two incorrect components from choices B and C. A BPP does not involve a Doppler ultrasound or a contraction stress test.

A. Maternal weight. B. Fetal heart rate. C. Gestational age. D. Placental function.

Correct Answer is C

Explanation

The level of AFP in a pregnant woman’s blood depends on how far along she is in her pregnancy.

AFP levels are normally high in the early weeks of pregnancy and then decline as the pregnancy progresses.

If the AFP level is too high or too low for the gestational age, it may indicate a problem with the baby’s development.

Choice A is wrong because maternal weight does not affect AFP levels.

Choice B is wrong because fetal heart rate does not affect AFP levels.

Choice D is wrong because the placental function does not affect AFP levels directly, but it may affect the levels of other hormones that are measured along with AFP in a quad screen.
