A nurse receives a report about a client who is in labor and is having contractions 3 min apart. Which of the following patterns should the nurse expect on the fetal monitoring tracing?
Contractions that last for 60 seconds each with a 2-min rest between contractions
Contractions that last for 60 seconds each with a 3-min rest between contractions
A contraction that lasts 3 min followed by a period of relaxation
Contractions that last 45 seconds each with a 2-min rest between contractions
The Correct Answer is A
A. Contractions that last for 60 seconds each with a 2-min rest between contractions. If contractions are 3 minutes apart, this means the interval from the start of one contraction to the start of the next is 3 minutes. If each contraction lasts for 60 seconds, there will be a 2-minute rest period before the next contraction begins.
B. Contractions that last for 60 seconds each with a 3-min rest between contractions. This would indicate contractions occurring every 4 minutes, not every 3 minutes.
C. A contraction that lasts 3 min followed by a period of relaxation. A contraction lasting 3 minutes is abnormal and suggests uterine tachysystole, which can be dangerous.
D. Contractions that last 45 seconds each with a 2-min rest between contractions. If contractions last 45 seconds, the remaining rest period would be 2 min 15 sec, not exactly 2 minutes.

Correct Answer is D
Explanation
A. A client who has a history of preterm labor. A history of preterm labor is not an indication for MSAFP screening. MSAFP is primarily used to detect neural tube defects (e.g., spina bifida) and chromosomal abnormalities (e.g., Down syndrome).
B. A client who has been exposed to AIDS. HIV/AIDS exposure does not impact MSAFP levels and is not an indication for the test. The focus in these clients is viral load monitoring and antiretroviral therapy.
C. A client who has mitral valve prolapse. Mitral valve prolapse does not affect fetal development in a way that would require MSAFP screening.
D. All of the clients. It is a standard screening test offered to all pregnant clients during the second trimester. The test is recommended for detecting fetal neural tube defects and certain chromosomal abnormalities, typically offered between 15-20 weeks of gestation.
Correct Answer is D
Explanation
A. To determine the exact gestational age of the fetus. Gestational age is estimated via ultrasound and fundal height, not an NST.
B. To measure the amniotic fluid volume. Amniotic fluid volume is assessed with an ultrasound and amniotic fluid index (AFI), not an NST.
C. To confirm the presence of labor contractions. An NST does not confirm labor contractions; it evaluates fetal heart rate in response to fetal movement.
D. To assess fetal well-being in cases of suspected fetal growth restriction. An NST evaluates fetal oxygenation and well-being, making it useful in cases of intrauterine growth restriction (IUGR) or other concerns about fetal health.
