A nurse is caring for a patient scheduled for a maternal serum alpha-fetoprotein test at 15 weeks of gestation.
Which explanations about this test should the nurse provide to the patient?
This test is a screening for spinal defects in the fetus.
This test assesses various markers of fetal well-being.
This test identifies an Rh incompatibility between the mother and fetus.
This test assesses fetal lung maturity.
The Correct Answer is A
Choice A rationale
The maternal serum alpha-fetoprotein test is a part of what’s often called the “triple screen” that can assess whether a pregnant woman may be at increased risk of carrying a baby with certain disorders, such as neural tube defects (spinal defects) or Down syndrome.
Choice B rationale
While the test can provide information about the risk of certain birth defects, it does not assess various markers of fetal well-being.
Choice C rationale
The test does not identify an Rh incompatibility between the mother and fetus. That would be determined through separate blood tests.
Choice D rationale
The test does not assess fetal lung maturity. Other tests, such as amniocentesis, can provide this information.

Correct Answer is D
Explanation
Choice A rationale
Bleeding or spotting can accompany implantation. This is a common occurrence and does not necessarily indicate a problem with the pregnancy. It happens when the fertilized egg attaches to the lining of the uterus. Some women may mistake this bleeding for a light period, but it’s a sign of pregnancy.
Choice B rationale
Fertilization typically takes place in the outer third of the fallopian tube. After ovulation, the egg travels down the fallopian tube towards the uterus. If sperm are present in the fallopian tube at this time, fertilization can occur. This is a normal part of the reproductive process.
Choice C rationale
Sperm can remain viable in the woman’s reproductive tract for 2 to 3 days. This means that intercourse does not have to coincide exactly with ovulation in order to achieve pregnancy. The sperm can survive long enough to fertilize the egg when it is released.
Choice D rationale
The statement “Implantation occurs between 2 and 3 weeks after conception” is incorrect and requires intervention by the nurse. Implantation actually occurs about 6-10 days after ovulation, which is less than 2 weeks after conception.
Correct Answer is B
Explanation
The correct answer is B. Anticonvulsants. Anticonvulsants can interfere with the effectiveness of a combined oral contraceptive (COC)10111213. These medications can increase the metabolism of COCs, thereby reducing their effectiveness and potentially leading to contraceptive failure.
