A nurse is caring for a client during a nonstress test (NST). At the end of a 30min period of observation, the nurse notes the following findings: The fetal heart rate baseline is 120/min with minimal variability and no accelerations. There are two decelerations of 15 /min in the fetal heart rate during a period of fetal movement, each lasting 20 seconds. Which of the following
interpretations of these findings should the nurse make?
A reactive test
A negative test
A positive test
A nonreactive test
The Correct Answer is D
A) A reactive test: A reactive NST requires the presence of specific criteria, including at least two fetal heart rate accelerations of at least 15 beats per minute (bpm) lasting for at least 15
seconds in a 20minute period, along with a baseline heart rate within the normal range (110160 bpm) and moderate variability.
B) A negative test: "Negative" is not a term used to describe NST results.
C) A positive test: "Positive" is not a term used to describe NST results.
D) A nonreactive test: This is the correct interpretation. In a nonreactive NST, the fetal heart rate did not demonstrate the required accelerations within the 30minute observation period. The absence of accelerations can indicate potential fetal compromise, and further evaluation, such as a contraction stress test or biophysical profile, may be necessary to assess the fetus's wellbeing.

Correct Answer is C
Explanation
Choice A: Posterior neck flexion is not an expected change during pregnancy.
Choice B: Increased abdominal muscle tone is not an expected change during pregnancy. In fact, the abdominal muscles tend to stretch and may become less toned as the uterus expands.
Choice C: During pregnancy, the woman's center of gravity shifts due to the growing uterus, leading to an increased arch in the lower back known as lordosis. This change helps to maintain balance and reduce the strain on the back. The other options are not expected physiologic changes during pregnancy.
Choice D: Decreased mobility of pelvic joints is not an expected change during pregnancy. Some joint laxity may occur due to hormonal changes, but decreased mobility is not typical.
Correct Answer is C
Explanation
The correct answer is: c. The cervix is 1 cm dilated.
Choice A reason:
The presenting part is 1 cm above the ischial spines. This statement would be documented as -1 station. Fetal station is measured in centimeters relative to the ischial spines, with negative numbers indicating the presenting part is above the spines.
Choice B reason:
The cervix is effaced 1 cm. Effacement is measured in percentages, not centimeters. It refers to the thinning of the cervix, which progresses from 0% (not effaced) to 100% (fully effaced).
Choice C reason:
In obstetrics, a sterile vaginal exam (SVE) is recorded using a standard three-part shorthand: Dilation / Effacement / Station.Dilation: This is always the first number in the sequence. It measures the opening of the cervix from 0 to 10 centimeters. Therefore, if the finding begins with the number 1, it indicates the cervix has opened to a diameter of 1 cm.
Choice D reason:
The presenting part is 1 cm below the ischial spines. This would be documented as +1 station. Positive numbers indicate the presenting part is below the ischial spines, moving towards delivery.
