A nurse is providing teaching to a client who is at 30 weeks of gestation and is to have a nonstress test (NST). Which of the following statements by the client indicates a need for further teaching?
"I will have to lie on my back during the test."
"My baby's heart rate will be monitored during the test."
"It will take 20 to 30 minutes to complete the test."
"I should schedule the test when the baby is usually active."
The Correct Answer is A
Choice A: The client should not lie on her back during the NST because the supine position can compress the vena cava and reduce blood flow to the placenta and the baby. The NST is typically done with the client in a semireclined or left lateral position to ensure optimal blood flow to the baby.
Choice B: Monitoring the baby's heart rate is a correct statement and a standard part of the NST procedure.
Choice C: The duration mentioned (20 to 30 minutes) is accurate for the average NST timeframe.
Choice D: Scheduling the NST when the baby is usually active is also a correct statement, as fetal movement during the test is an important aspect of evaluating fetal wellbeing.

Correct Answer is C
Explanation
Choice A: Fetal movements, also known as quickening, are usually felt by the mother between weeks 18 and 25 of pregnancy, not specifically at week 24.
Choice B: While the sex of the baby is determined at conception, it is not visually identifiable on ultrasound until around week 16 to 20, depending on the fetus's position and the quality of the ultrasound images.
Choice C: The baby's heartbeat can be visualized on ultrasound as early as 6 weeks of pregnancy. It becomes audible using a Doppler stethoscope around 8 to 9 weeks of pregnancy.
Choice D: Lanugo, the fine hair covering the baby's body, usually appears around weeks 20 to 24 of pregnancy and begins to diminish later in pregnancy, not specifically at week 36.
Correct Answer is D
Explanation
Choice A: Fetal lung maturity is not assessed through maternal serum alphafetoprotein testing. It is usually evaluated through tests such as amniocentesis or specialized ultrasound examinations closer to the third trimester.
Choice B: The maternal serum alphafetoprotein test specifically screens for certain birth defects and genetic conditions in the fetus, rather than general signs of physical and physiological
wellbeing.
Choice C: The maternal serum alphafetoprotein test is not used to identify Rh incompatibility. Rh incompatibility is determined through blood tests that assess the Rh factor of the mother's blood and the Rh status of the baby.
Choice D: The maternal serum alphafetoprotein test is a blood screening test that can identify neural tube defects (such as spina bifida) and chromosomal abnormalities (such as Down syndrome) in the fetus. The test measures the levels of alphafetoprotein in the mother's blood, and abnormal levels may indicate the need for further diagnostic testing.
