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.”.
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
A Doppler ultrasound blood flow analysis measures the velocity of blood flow in the uterine and fetal vessels.
This test can help assess the fetal well-being and oxygenation in cases of intrauterine growth restriction (IUGR).
Choice B is wrong because the amount of amniotic fluid in the uterine cavity is measured by ultrasound, not Doppler.
Choice C is wrong because the pressure of blood flow in the umbilical cord is not directly measured by Doppler, but rather inferred from the resistance index or pulsatility index.
Choice D is wrong because the oxygen saturation level of fetal blood is not measured by Doppler, but rather by fetal scalp sampling or pulse oximetry.
Correct Answer is A
Explanation
A contraction stress test (CST) is performed near the end of pregnancy to determine how well the fetus will cope with the contractions of childbirth.
The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.
A normal heartbeat is a good sign that the fetus will be healthy during labor.
Choice B is wrong because a CST does not measure maternal blood pressure.
Choice C is wrong because a CST does not assess placental function directly.
Choice D is wrong because a CST does not measure amniotic fluid volume.
Normal ranges for fetal heart rate are between 110 and 160 beats per minute.
Normal ranges for uterine contractions are between 2 and 5 contractions in 10 minutes, lasting less than 90 seconds each.
