A nurse is educating a pregnant client about the Contraction Stress Test (CST).

Which statement accurately describes a negative CST?

No contractions were induced during the test.

Late decelerations of the FHR were observed with at least 50% of contractions.

The FHR remained stable throughout the test.

The client experienced mild uterine cramping during the tes.

Answer and Explanation

The Correct Answer is C

This means that the baby’s heart rate did not slow down after the contractions induced by oxytocin, which is a sign of normal fetal well-being.

A negative CST is normal and desirable.

Choice A is wrong because no contractions were induced during the test.

This means that the test was inconclusive and could not assess the baby’s response to stress.

Choice B is wrong because late decelerations of the FHR were observed with at least 50% of contractions.

This means that the baby’s heart rate slowed down and stayed slow after the contractions, which is a sign of fetal distress and hypoxia.

A positive CST is abnormal and concerning.

Choice D is wrong because the client experienced mild uterine cramping during the test.

This is not a relevant factor for interpreting the CST results, which depend on the FHR patterns.

Uterine cramping can be a side effect of oxytocin administration or nipple stimulation.

Correct Answer is B

Explanation

There are no known risks or complications for the pregnant person or the fetus.

Prenatal ultrasound is a safe and noninvasive procedure that uses sound waves to create images of the fetus and the placenta.

It does not use radiation or harm the fetal tissues.

Choice A is wrong because ultrasound does not cause harm to the fetus.

There is no evidence that ultrasound has any adverse effects on fetal development, growth, or health.

Choice C is wrong because pregnant individuals do not need to avoid ultrasound due to potential radiation exposure.

Ultrasound does not involve radiation, unlike x-rays or CT scans.

Choice D is wrong because ultrasound does not lead to miscarriage or preterm labor.

Ultrasound is not associated with any increased risk of pregnancy complications, such as miscarriage, preterm labor, or birth defects.

A. “The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”. B. “The patient should wear tight-fitting clothing and lie prone on an examination table.”. C. “The patient should wear loose-fitting clothing and lie supine on an examination table.”. D. “The patient should wear loose-fitting clothing and lie prone on an examination table.”.

Correct Answer is A

Explanation

“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”1 This is because a full bladder helps to lift the uterus and improve the visibility of the pelvic organs in a transabdominal US, while an empty bladder prevents distortion of the image in a transvaginal US.

Choice B is wrong because tight-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.

Choice C is wrong because loose-fitting clothing is not necessary and lying supine on an examination table may cause supine hypotension syndrome in pregnant women.

Choice D is wrong because loose-fitting clothing is not necessary and lying prone on an examination table is uncomfortable and may interfere with the insertion of the vaginal probe.
