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 B

Explanation

This test can detect genetic disorders.

Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems.

The placenta is a structure in the uterus that provides blood and nutrients from the mother to the fetus.

Choice A is wrong because CVS does not provide information on neural tube defects, such as spina bifida.

For this reason, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.

Choice C is wrong because CVS can detect chromosomal abnormalities, but not all chromosomal abnormalities are genetic disorders.

For example, Down syndrome is a chromosomal abnormality caused by an extra copy of chromosome 21, but it is not inherited from the parents.

Choice D is wrong because CVS cannot detect Rh sensitization, which is a condition where the mother’s immune system produces antibodies against the fetus’s blood type.

Rh sensitization can be detected by a blood test that measures the level of antibodies in the mother’s blood.

A. Nipple stimulation. B. Intravenous oxytocin infusion. C. Administering oral medications. D. Applying warm compresses to the abdomen.

Correct Answer is B

Explanation

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.
