A client is scheduled for a transvaginal ultrasound in two weeks.

The client asks the nurse what they should do to prepare for the test.

What is the best response by the nurse?

“The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”.

“The patient should wear tight-fitting clothing and lie prone on an examination table.”.

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

“The patient should wear loose-fitting clothing and lie prone on an examination table.”.

Answer and Explanation

The Correct Answer is A

“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.

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

A. It is a diagnostic test for spinal defects in the fetus. B. It is a screening test for spinal defects in the fetus. C. It is a diagnostic test for chromosomal abnormalities in the fetus. D. It is a screening test for chromosomal abnormalities in the fetu.

Correct Answer is B

Explanation

A maternal serum alpha-fetoprotein test is a type of prenatal blood test that measures the levels of MSAFP in the blood of a pregnant person.The test helps the healthcare provider assess the baby’s risk of certain medical conditions, such as neural tube defects and chromosomal abnormalities.The test is usually done between 15 and 20 weeks of pregnancy.

A screening test means that it does not diagnose any health conditions, but only indicates the probability of having them.

A positive test means that the baby has a higher risk of having a birth defect, but it does not confirm it.

A negative test means that the baby has a lower risk of having a birth defect, but it does not rule it out.Further tests are needed to confirm or exclude the diagnosis.

A diagnostic test means that it can provide a definite diagnosis of a health condition.A maternal serum alpha-fetoprotein test is not a diagnostic test for spinal defects or chromosomal abnormalities in the fetus.

Statement A is wrong because it says that the test is a diagnostic test for spinal defects in the fetus, which is not true.

Statement C is wrong because it says that the test is a diagnostic test for chromosomal abnormalities in the fetus, which is not true.

Statement D is wrong because it says that the test is a screening test for chromosomal abnormalities in the fetus, which is only partially true.The test can screen for some chromosomal abnormalities, such as Down syndrome, but not all of them.

The test also screens for neural tube defects, which are not chromosomal abnormalities.

Normal ranges for MSAFP vary depending on the gestational age and the laboratory methods used.Generally, MSAFP levels increase until about 32 weeks of pregnancy and then decrease until delivery.

High levels of MSAFP may indicate neural tube defects, multiple pregnancies, incorrect dating of pregnancy, or other conditions.Low levels of MSAFP may indicate Down syndrome, other chromosomal abnormalities, or other conditions.
