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 B
Explanation
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
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.
