A client asks the nurse about the risks and complications associated with prenatal ultrasound.

Which of the following responses by the nurse is accurate?

"Ultrasound may cause harm to the fetus.".

"There are no known risks or complications for the pregnant person or the fetus.".

"Pregnant individuals should avoid ultrasound due to potential radiation exposure.".

"Ultrasound can lead to miscarriage or preterm labor.".

Answer and Explanation

The Correct Answer is B

There are no known risks or complications for the pregnant person or the fetus.

Prenatal ultrasound is a safe and noninvasive procedure that uses sound waves to create images of the fetus and the placenta.

It does not use radiation or harm the fetal tissues.

Choice A is wrong because ultrasound does not cause harm to the fetus.

There is no evidence that ultrasound has any adverse effects on fetal development, growth, or health.

Choice C is wrong because pregnant individuals do not need to avoid ultrasound due to potential radiation exposure.

Ultrasound does not involve radiation, unlike x-rays or CT scans.

Choice D is wrong because ultrasound does not lead to miscarriage or preterm labor.

Ultrasound is not associated with any increased risk of pregnancy complications, such as miscarriage, preterm labor, or birth defects.

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. “The patient should have a full bladder for a transabdominal US and an empty bladder for a transvaginal US.”. B. “The patient should wear tight-fitting clothing and lie prone on an examination table.”. C. “The patient should wear loose-fitting clothing and lie supine on an examination table.”. D. “The patient should wear loose-fitting clothing and lie supine on an examination table.”.

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.
