A client's Alpha-fetoprotein Test (AFP) result is reported as 0.8 MoM.
What does this result suggest?
Normal level of AFP for the given gestational age.
High level of AFP indicating a neural tube defect.
Low level of AFP indicating a potential chromosomal abnormality.
Inconclusive result, requiring further evaluation.
The Correct Answer is A
This result suggests that the baby has a low risk of having a genetic disorder or a neural tube defect.
Choice B is wrong because a high level of AFP indicating a neural tube defect would be greater than 2 MoM.
Choice C is wrong because a low level of AFP indicating a potential chromosomal abnormality would be less than 0.5 MoM.
Choice D is wrong because an inconclusive result, requiring further evaluation, would depend on other factors such as ultrasound findings and maternal age.
MoM stands for multiples of the median, which is a way of comparing the AFP level of a pregnant person to the average level for their gestational age.
Values between 0.5 and 2.49 MoM are considered normal.

Correct Answer is A
Explanation
The correct answer is choice A. Notify the health care provider immediately.
This is because cramping and vaginal bleeding 24 hours after amniocentesis are signs of possible complications, such as injury to the baby or mother, leaking of amniotic fluid, infection, Rh sensitization, preterm labor, or miscarriage.
These complications are rare, but they can be serious and require immediate medical attention.
Choice B is wrong because administering pain medication to the patient does not address the underlying cause of the cramping and bleeding, and may delay seeking help.
Choice C is wrong because encouraging the patient to rest and elevate her legs may not prevent further complications, and may also delay seeking help.
Choice D is wrong because offering emotional support and reassurance to the patient is not enough to ensure the safety of the baby and the mother, and may give a false sense of security.
Normal ranges for amniocentesis are:
No chromosomal defects detected in the fetus and no abnormal proteins present in amniotic fluid
No signs of infection or other illness in the baby
Fetal lungs mature enough for birth if delivery is planned sooner than 39 weeks
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.
