- A. DNA
- B. Plastoderm

What is the term for a nonstress test in which there are two or more fetal heart rate accelerations of 15 or more beats per minute (BPM) with fetal movement in a 20-minute period?
- A. Positive
- B. Negative
- C. Reactive
- D. Nonreactive
Correct Answer: C
Rationale: A nonstress test is considered reactive when there are at least two accelerations of 15 BPM or more in a 20-minute period, indicating fetal well-being.
Which fetal structures are well-formed by the end of the first trimester? Select all that apply.

A client is 35 weeks’ gestation.
- A. Nausea and vomiting.
- B. Maternal ambivalence.
- C. Fundal height 10 cm above the umbilicus.
- D. Use of three pillows for sleep comfort.

What assessment data are collected to assess progress during the second stage of labor?
- A. fetal heart rate
- B. fetal descent
- C. bearing-down effort
- D. contraction strength
Correct Answer: B
Rationale: The correct answer is B: fetal descent. During the second stage of labor, assessing fetal descent is crucial to monitor progress. This data helps determine if the baby is moving down the birth canal appropriately. Fetal descent indicates the effectiveness of contractions and pushing efforts. It is a key indicator of labor progression.
Rationale:
- A: Fetal heart rate is important but primarily assesses fetal well-being, not progress during the second stage of labor.
- C: Bearing-down effort is relevant for pushing but does not directly measure progress in terms of fetal descent.
- D: Contraction strength is essential but does not specifically indicate the progress of the baby's descent in the birth canal during the second stage of labor.
