A nurse is explaining the purpose of an Alpha-fetoprotein Test (AFP) to a pregnant client.

What is the test primarily used for ?

Screening for neural tube defects.

Assessing placental function.

Determining fetal gender

Diagnosing chromosomal abnormalities

Answer and Explanation

The Correct Answer is A

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.

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.

A. “I will have an ultrasound-guided needle inserted through my abdomen and uterus.”. B. “I will have an ultrasound-guided catheter inserted through my cervix.”. C. “I will have an ultrasound-guided needle inserted through my cervix.”. D. “I will have an ultrasound-guided catheter inserted through my abdomen and uterus.”

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.
