A client is scheduled for an abdominal ultrasound in two weeks to assess fetal growth and development during pregnancy.
Which of these statements made by the client indicates that further teaching is needed?
“I will drink plenty of fluids before my appointment.”
“I will eat a light meal before my appointment.”
“I will wear comfortable clothing.”
“I will arrive at my appointment with a full bladder."
The Correct Answer is B
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

Correct Answer is B
Explanation
Choice A is wrong because it describes a transabdominal CVS procedure, which involves a needle instead of a catheter.
Choice C is wrong because it describes a procedure that is not used for CVS.A needle inserted through the cervix could damage the fetal membranes or cause bleeding.
Choice D is wrong because it describes a procedure that is not possible.A catheter cannot be inserted through the abdomen and uterus into the placenta.
Normal ranges for CVS are not applicable as it is a diagnostic test, not a screening test.
It provides a definitive result of whether the fetus has a chromosomal abnormality or a genetic disorder.CVS is usually done between 10 and 13+6 weeks of pregnancy.
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.
