A couple who are pregnant with their first child have made an appointment with a clinical geneticist to discuss prenatal screening
The man states that they, "just want to make sure that there is nothing wrong with our baby." How could the clinician best respond to this statement?
A)
"We can't rule out all abnormalities, but a routine fetal tissue biopsy can yield useful information."
B)
"Testing the umbilical blood and performing amniocentesis can give us some information, but not a guarantee."
C)
"Prenatal screening is not usually necessary unless you are among a high-risk group."
D)
"You need to be aware that if abnormalities are detected, termination is normally required."
Ans:
B
Feedback:
Prenatal screening provides a useful, but incomplete, picture of fetal health; umbilical sampling and amniocentesis are common methods of screening. Fetal tissue biopsy is a rarely used screening method, and a couple need not belong to a high-risk group to benefit from prenatal screening. Abnormalities do not usually necessitate termination.
