A pregnant woman.
Question 2 of 5
The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy. The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:

Question 3 of 5
What is the result of a nonstress test (NST) in which two or more fetal heart rate (FHR) accelerations of 15 beats/min or more occur with fetal movement in a 20-minute period?

Question 4 of 5
What should the nurse tell a pregnant woman at 10 weeks of gestation who jogs 3 or 4 times per week and is concerned about the effect of exercise on the fetus?
Correct Answer: A
Rationale: Jogging is safe early but may need adjustment to walking later for comfort, not joint harm or fetal risk, and modification is often needed.
Extract:
An antepartum woman undergoing a contraction stress test (CST).
Question 5 of 5
What should a nurse know about the contraction stress test (CST) when providing care for the antepartum woman?
Correct Answer: B
Rationale: A negative CST, with no late decelerations, indicates fetal tolerance to contractions, unlike vibroacoustic use, invasiveness, or membrane rupture scenarios.
