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.

Answer and Explanation

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 ["A","B","C","E"]

Explanation

Choice A rationale

Anomalies in fetal chromosomes can be identified through amniocentesis. This test involves the extraction of a small amount of amniotic fluid, which contains fetal tissues. The chromosomes of the fetus can be examined for abnormalities.

Choice B rationale

Cephalopelvic disproportion refers to a condition where the mother’s pelvis is too small to allow the baby to pass through the birth canal. This condition cannot be identified through amniocentesis. Amniocentesis is a diagnostic procedure that examines the amniotic fluid (not the maternal pelvis or the size of the fetus) to detect chromosomal abnormalities and certain genetic disorders.

Choice C rationale

Fetal gender can be determined through amniocentesis. The test can identify the presence of Y chromosomes, which would indicate a male fetus.

Choice D rationale

Rh incompatibility is a condition that occurs when a mother is Rh-negative and the baby is Rh-positive. This condition cannot be identified through amniocentesis. Instead, it is typically identified through blood tests of the mother and father.

Choice E rationale

Neural tube defects, such as spina bifida and anencephaly, can be identified through amniocentesis. The test can detect high levels of alpha-fetoprotein, which is often present when a fetus has a neural tube defect.

A. Prescription A B. Prescription B C. Prescription C D. Prescription D

Correct Answer is B

Explanation

Choice A rationale

The symptoms described do not typically align with conditions that would be treated with Prescription A. Prescription A might be used for a different set of symptoms or conditions.

Choice B rationale

The presence of small pinpoint open vesicles and pustules on the labia majora with clear drainage, along with a thick, mucopurulent vaginal discharge, could indicate a sexually transmitted infection or other type of infection. Prescription B might be an antibiotic or antiviral medication to treat the suspected infection.

Choice C rationale

The symptoms described do not typically align with conditions that would be treated with Prescription C. Prescription C might be used for a different set of symptoms or conditions.

Choice D rationale

The symptoms described do not typically align with conditions that would be treated with Prescription D. Prescription D might be used for a different set of symptoms or conditions.
