A nurse is caring for a client scheduled for a CST.
Which statement indicates the client understands the test procedure?
"I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.".
"I will need to fast for 24 hours before the test.".
"I will be sedated during the test to prevent discomfort.".
"I will need to drink plenty of fluids before the test.".
The Correct Answer is A
“I will have sensors placed on my abdomen to monitor the FHR and uterine contractions.” This statement indicates the client understands the test procedure of a CST, which is a test that triggers contractions and registers how the baby’s heart reacts.
The test is done by placing two sensor belts around the abdomen, one to measure the baby’s heartbeat and the other to measure contractions.
The client may receive oxytocin through an IV to induce contractions.
Choice B is wrong because the client does not need to fast for 24 hours before the test.
There is no evidence that fasting is required for a CST.
Choice C is wrong because the client will not be sedated during the test.
Sedation is not necessary for a CST and may interfere with the results.
Choice D is wrong because the client does not need to drink plenty of fluids before the test.
There is no evidence that drinking fluids is required for a CST.

Correct Answer is B
Explanation
AFP is a screening tool that can indicate the possibility of certain fetal anomalies, such as neural tube defects, abdominal wall defects, or chromosomal abnormalities.
However, AFP results are not diagnostic and cannot confirm the presence or absence of these conditions.
Therefore, further tests, such as ultrasound or amniocentesis, are needed to verify the results.
Choice A is wrong because AFP results are not diagnostic for fetal anomalies.
They only indicate a risk level that needs to be confirmed by other tests.
Choice C is wrong because AFP results can detect not only neural tube defects, but also other fetal anomalies, such as abdominal wall defects or chromosomal abnormalities.
Choice D is wrong because AFP results are not affected by maternal race and ethnicity.
They are affected by maternal age, weight, diabetes, multiple gestation, and gestational age.
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 that occurs randomly and 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 cells.
Rh sensitization can be detected by a blood test that measures the level of antibodies in the mother’s blood.
