A nurse is reviewing the contraindications for a Contraction Stress Test (CST) with a pregnant client.

Which condition would be a contraindication for the test?

Gestational diabetes.

Mild preeclampsia.

Preterm labor.

Ruptured membranes.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is C

Explanation

The patient should wear loose-fitting clothing and lie supine on an examination table.

This is because loose-fitting clothing allows easy access to the abdomen and lying supine helps relax the abdominal muscles.

The patient should also avoid food and drinks for 8 to 12 hours before the test, as undigested food can interfere with the sound waves and affect the image quality.

Choice A is wrong because a full bladder is not necessary for an abdominal ultrasound, unless the patient is pregnant or has a pelvic condition.

A transvaginal ultrasound is a different type of ultrasound that uses a probe inserted into the vagina to examine the reproductive organs.

Choice B is wrong because tight-fitting clothing can restrict the movement of the ultrasound probe and make it harder to get a clear image.

Lying prone (on the stomach) can also tense up the abdominal muscles and obscure the organs.

Choice D is wrong because lying prone can have the same disadvantages as choice B. Additionally, wearing loose-fitting clothing does not mean that the patient can eat or drink anything before the test, as this can affect the results.

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
