A client is scheduled for a maternal serum alpha-fetoprotein test at 15 weeks of gestation. The client asks the nurse about the purpose of this test. What explanation should the nurse provide?

  • A. This test screens for neural tube defects and other developmental abnormalities in the fetus.
  • B. It assesses various markers of fetal well-being.
  • C. This test identifies an Rh incompatibility between the mother and fetus.
  • D. It is a screening test for spinal defects in the fetus.
Correct Answer: A

Rationale: The correct answer is A because the maternal serum alpha-fetoprotein test is specifically used to screen for neural tube defects and other developmental abnormalities in the fetus. Alpha-fetoprotein levels in the mother's blood can indicate the presence of such abnormalities. This test is typically done around 15-20 weeks of gestation.

Choice B is incorrect because the maternal serum alpha-fetoprotein test is not used to assess various markers of fetal well-being. Choice C is incorrect because it does not identify Rh incompatibility, which is typically detected through other tests. Choice D is incorrect because the test is not primarily for spinal defects, but rather for neural tube defects and other developmental abnormalities.
