A nurse is caring for a client who had chorionic villus sampling (CVS) performed at 12 weeks’ gestation and asks when she can expect results from this test.
The nurse should inform her that results are typically available within which timeframe?
24 hours
7 days.
10-14 days.
30 days.
The Correct Answer is B
The correct answer is choice B. The nurse should inform her that results are typically available within 7 days.
This is known as the rapid CVS result.
A more detailed set of CVS results will be available within 2 weeks.
Choice A is wrong because 24 hours is too short for the laboratory to test the sample of cells from the placenta.
Choice C is wrong because 10-14 days is the timeframe for the more detailed set of CVS results, not the rapid CVS result.
Choice D is wrong because 30 days is too long for the results to be available.
The woman would need to know the results sooner to make informed decisions about her pregnancy.

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.
Correct Answer is B
Explanation
This method can be used to induce uterine contractions during the test by stimulating the uterus with a hormone that causes contractions.
Oxytocin is also the hormone that naturally triggers labor contractions.
Choice A is wrong because nipple stimulation can also induce contractions, but it is not as reliable or controllable as oxytocin infusion.
Choice C is wrong because oral medications are not used to induce contractions during a CST.
Some medications may interfere with the test results or cause side effects.
Choice D is wrong because applying warm compresses to the abdomen does not induce contractions.
It may help with pain relief or relaxation, but it does not affect the uterus.
Normal ranges for uterine contractions during a CST are three contractions in 10 minutes, each lasting 40 to 60 seconds.
Normal ranges for fetal heart rate during a CST are 110 to 160 beats per minute, with no decelerations after contractions.
