A nurse is educating a pregnant client about the Non-Stress Test (NST).

Which statement by the client indicates understanding of the test?

"NST is performed after 28 weeks of gestation or earlier if there are risk factors.".

"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.".

. "NST requires placing two belts with sensors on my abdomen: one to monitor the fetal heart rate and one to monitor the uterine contractions.".

"A reactive NST may indicate fetal hypoxia, distress, sleep, medication effect, or neurological abnormality.".

Answer and Explanation

The Correct Answer is A

"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

Correct Answer is B

Explanation

This is because cramping and vaginal bleeding after an amniocentesis may indicate a possible miscarriage or placental abruption, which can compromise fetal oxygenation and perfusion.

Monitoring fetal heart rate can help detect signs of fetal distress and guide further interventions.

Choice A is wrong because administering Rho(D) immune globulin is indicated for Rh-negative mothers who undergo amniocentesis to prevent isoimmunization, but it is not a priority action in this scenario.

Choice C is wrong because assessing maternal vital signs is important to monitor for signs of infection, hemorrhage, or shock, but it is not as urgent as monitoring fetal well-being.

Choice D is wrong because obtaining an order for an ultrasound exam can help confirm the diagnosis and evaluate the placenta and amniotic fluid, but it is not the first action to take in this situation.

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 supine on an examination table.”.

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.
