The nurse reviews a client’s antepartum nonstress test results as reactive. The nurse interprets this finding as:
Two or more fetal heart rate accelerations within a 20-minute period.
No late decelerations of the fetal heart rate.
Late decelerations are present with a minimum of 50% of the contractions.
Fetal heart rate accelerations less than 15 beats per minute or lasting less than 15 seconds.
The Correct Answer is A
Choice A rationale
A reactive nonstress test is defined as having two or more fetal heart rate accelerations of at least 15 beats per minute lasting 15 seconds or more within a 20-minute period.
Choice B rationale
No late decelerations of the fetal heart rate do not define a reactive nonstress test, which focuses on fetal heart rate accelerations as indicators of fetal well-being.
Choice C rationale
The presence of late decelerations in more than 50% of contractions indicates uteroplacental insufficiency and fetal distress, not a reactive nonstress test which requires accelerations.
Choice D rationale
Fetal heart rate accelerations less than 15 beats per minute or lasting less than 15 seconds do not meet the criteria for a reactive nonstress test, which requires accelerations of 15 beats per minute lasting 15 seconds or more.

Correct Answer is C
Explanation
Choice A rationale
Dysuria, while concerning, is typically less urgent compared to the complete absence of fetal movement, which can indicate fetal distress or demise.
Choice B rationale
Nausea is a common symptom during pregnancy and generally less urgent compared to the absence of fetal movement, which may indicate a serious issue.
Choice C rationale
No fetal movement is a critical concern as it may indicate fetal demise or severe distress requiring immediate assessment and intervention to ensure fetal well-being.
Choice D rationale
A cough in pregnancy can be bothersome but is generally not as urgent compared to the absence of fetal movement, which can indicate potential fetal demise.
Correct Answer is D
Explanation
Choice A rationale
Evaluating the fetal heart rate does not address maternal symptoms of supine hypotensive syndrome. Moving the client first corrects the underlying issue. Fetal evaluation can follow once maternal circulation improves, ensuring both are assessed.
Choice B rationale
Checking recent food and fluid intake does not immediately address the likely cause of supine hypotensive syndrome. Correcting maternal positioning is urgent to improve venous return and prevent adverse effects, then other assessments can follow.
Choice C rationale
Measuring blood pressure and pulse can confirm hypotension but does not address its cause. Immediate repositioning to lateral position alleviates the compression on the inferior vena cava, improving blood flow before measuring vitals.
Choice D rationale
Turning to a lateral position relieves the vena cava from compression by the gravid uterus, reducing symptoms of supine hypotensive syndrome. This action improves venous return, stabilizing maternal hemodynamics and alleviating dizziness and pallor.
