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.".
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 C
Explanation
According to the ACOG guidelines on antepartum fetal surveillance, one of the components of the biophysical profile is fetal breathing movements, which are scored as 2 points if there is one or more episodes of rhythmic fetal breathing movements of 30 seconds or more within 30 minutes.
Choice A is wrong because 0 points are given for absent or no breathing episode for ≥30 seconds within a 30 minute observation period.
Choice B is wrong because there is no 1 point score for this variable.
Choice D is wrong because there is no 3 point score for this variable.
The maximum score for each variable is 2 points.
Correct Answer is A
Explanation
An alpha-fetoprotein test (AFP) is a blood test that measures the amount of AFP present in blood.
It’s usually part of what’s called a triple screen or quad screen in the second trimester of pregnancy.
The yolk sac, GI tract, and liver of an unborn baby produce AFP.
It then circulates through the fetal and maternal blood.
High levels of AFP in pregnant people can indicate that the baby has a neural tube defect, such as spina bifida or anencephaly.
Choice B is wrong because assessing placental function is not the primary purpose of an AFP test.
However, low levels of AFP can indicate problems with the placenta or the baby’s growth.
Choice C is wrong because determining fetal gender is not the primary purpose of an AFP test.
However, some genetic tests that use a sample of the baby’s DNA from the pregnant person’s blood can reveal the baby’s sex as early as 10 weeks of pregnancy.
Choice D is wrong because diagnosing chromosomal abnormalities is not the primary purpose of an AFP test.
However, an AFP test is usually part of a quad screen that also tests for other markers that can indicate the risk of chromosomal abnormalities, such as Down syndrome.
