A client is scheduled for an abdominal 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 supine on an examination table.”.
The Correct Answer is C
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.

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
Correct Answer is B
Explanation
The client should not eat a light meal before an abdominal ultrasound because it can interfere with the quality of the images.
The client should fast for 8 to 12 hours before the procedure.
Some additional information about the other choices are:
Choice A is correct.
The client should drink plenty of fluids before an appointment for an abdominal ultrasound because it helps to fill the bladder and push the uterus up for better visualization.
Choice C is correct.
The client should wear comfortable clothing that can be easily removed or lifted up to expose the abdomen.
Choice D is correct.
The client should arrive at the appointment with a full bladder because it acts as an acoustic window and improves the quality of the ultrasound images.
Normal ranges for fetal growth and development during pregnancy vary depending on the gestational age, but some general parameters are:
Fetal heart rate: 110 to 160 beats per minute
Biparietal diameter: 2.4 to 9.5 cm
Crown-rump length: 0.8 to 8.4 cm
Femur length: 1.0 to 7.8 cm
Abdominal circumference: 9.4 to 35.6 cm
