A nurse is reinforcing teaching with a client who is 15 weeks pregnant about to undergo amniocentesis. This test can identify which traits or problems? Select all that apply.
Rh incompatibility is not directly identified through amniocentesis. Instead, it's typically assessed through blood tests that determine a woman's Rh factor and screen for Rh antibodies.
However, amniocentesis can provide information that might be relevant to Rh incompatibility, such as the fetal Rh type. If the mother is Rh-negative and the fetus is Rh-positive, there's a risk of Rh incompatibility.
Amniocentesis can detect neural tube defects (NTDs) like spina bifida and anencephaly.
It does this by measuring the levels of alpha-fetoprotein (AFP) in the amniotic fluid. AFP is a protein produced by the fetal liver, and elevated levels in the amniotic fluid can indicate an NTD.
Amniocentesis can accurately determine the fetal gender by examining the sex chromosomes present in the cells of the amniotic fluid.
Cephalopelvic disproportion (CPD) is a condition where the baby's head is too large to fit through the mother's pelvis. It's not diagnosed through amniocentesis.
CPD is usually suspected based on clinical findings like a slow progression of labor or a high fetal station, and it might be confirmed with imaging techniques like X-ray or ultrasound.
Amniocentesis is a valuable tool for diagnosing chromosomal defects, such as Down syndrome, Trisomy 18, and Trisomy 13. It does this by analyzing the chromosomes of the fetal cells present in the amniotic fluid.
Choice A:
Rh incompatibility is not directly identified through amniocentesis. Instead, it's typically assessed through blood tests that determine a woman's Rh factor and screen for Rh antibodies.
However, amniocentesis can provide information that might be relevant to Rh incompatibility, such as the fetal Rh type. If the mother is Rh-negative and the fetus is Rh-positive, there's a risk of Rh incompatibility.
Choice B:
Amniocentesis can detect neural tube defects (NTDs) like spina bifida and anencephaly.
It does this by measuring the levels of alpha-fetoprotein (AFP) in the amniotic fluid. AFP is a protein produced by the fetal liver, and elevated levels in the amniotic fluid can indicate an NTD.
Choice C:
