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 D

Explanation

This is a contraindication for the Contraction Stress Test (CST) because it increases the risk of infection and umbilical cord prolapse.

A CST is a test that measures the baby’s heart rate during uterine contractions induced by oxytocin or nipple stimulation.

Choice A is wrong because gestational diabetes is not a contraindication for the CST.

It is a condition that affects how the body processes glucose during pregnancy and may cause complications such as macrosomia (large baby), hypoglycemia (low blood sugar) or preeclampsia (high blood pressure and protein in urine).

Choice B is wrong because mild preeclampsia is not a contraindication for the CST.

It is a condition that causes high blood pressure and protein in urine after 20 weeks of pregnancy and may affect the placenta, kidneys, liver or brain.

Choice C is wrong because preterm labor is a relative contraindication for the CST, not an absolute one.

It means that the test may be performed if the benefits outweigh the risks, but it should be avoided if possible because it may trigger early labor or delivery.

Preterm labor is defined as regular uterine contractions with cervical changes before 37 weeks of pregnancy.

Normal ranges for blood pressure are below 120/80 mmHg, for glucose are 70-100 mg/dL (fasting) or below 140 mg/dL (2 hours after eating), and for protein in urine are less than 300 mg/24 hours.

A. "NST is performed after 28 weeks of gestation or earlier if there are risk factors.". B. "A nonreactive NST means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period.". C. . "NST requires placing two belts with sensors on my abdomen: one to monitor the fetal heart rate and one to monitor the uterine contractions.". D. "A reactive NST may indicate fetal hypoxia, distress, sleep, medication effect, or neurological abnormality.".

Correct Answer is A

Explanation

"NST is performed after 28 weeks of gestation or earlier if there are risk factors."12 This statement indicates that the client understands when and why an NST is done.

Choice B is wrong because it describes a reactive NST, not a nonreactive one.

A reactive NST means that the fetal heart rate increases by at least 15 beats per minute for at least 15 seconds twice or more in a 20-minute period.2

Choice C is wrong because it confuses NST with contraction stress test (CST), which requires monitoring uterine contractions.

NST does not involve contractions.2

Choice D is wrong because it describes possible causes of a nonreactive NST, not a reactive one.

A nonreactive NST may indicate fetal hypoxia, distress, sleep, medication effect, or neurological abnormality.2
