Correct Answer is C
Explanation
A. Give herself a hypertonic enema the day before the procedure. A hypertonic enema is not required for an amniocentesis. In fact, enemas are not part of the preparation for this procedure.
B. Wash her abdomen with soap and water the morning of the procedure. While general hygiene is always recommended, specific cleansing of the abdomen is not necessary for an amniocentesis.
C. Empty her bladder immediately prior to the procedure. At 23 weeks of gestation, the bladder should be emptied to prevent accidental puncture during the amniocentesis.
D. Refrain from eating breakfast the day of the procedure. Fasting is not necessary for an amniocentesis; the client can eat normally before the procedure.
Correct Answer is A
Explanation
A. This test will screen for neural tube defects. MSAFP is a screening tool used to detect neural tube defects (such as spina bifida and anencephaly) in the developing fetus. Elevated levels of AFP are associated with such defects.
B. This test will screen for ABO incompatibility. ABO incompatibility is detected through blood tests, not MSAFP. MSAFP screens for structural abnormalities, not blood group incompatibilities.
C. This test will screen for fetal maturity. MSAFP is not a test for fetal lung maturity. Tests for fetal lung maturity, such as the lecithin-sphingomyelin (L/S) ratio, are typically done later in pregnancy.
D. This test will screen for gestational diabetes. MSAFP is unrelated to gestational diabetes, which is diagnosed with a glucose tolerance test, not MSAFP.
