A nurse is reviewing the results of a nonstress test for a client who is at 37 weeks of gestation.
Which of the following findings indicates a reactive nonstress test?
Fetal heart rate (FHR) accelerations occur with fetal movement.
Late decelerations of the FHR occur with contractions.
Variable decelerations of the FHR.
FHR pattern with minimal variability.
The Correct Answer is A
Choice A rationale
Fetal heart rate (FHR) accelerations with fetal movement are a sign of a healthy and reactive nonstress test. This indicates that the fetus is well-oxygenated and there is no immediate distress.
Choice B rationale
Late decelerations of the FHR occur with contractions and are a concern for fetal hypoxia. This does not indicate a reactive nonstress test and instead suggests the need for further evaluation.
Choice C rationale
Variable decelerations are abrupt decreases in FHR and could indicate umbilical cord compression. This does not correlate with a reactive nonstress test.
Choice D rationale
FHR pattern with minimal variability can be a sign of fetal distress or compromised oxygenation. It is not indicative of a reactive nonstress test.

Correct Answer is D
Explanation
Choice A rationale
Transient circumoral cyanosis is common in newborns, especially when crying or feeding, and usually resolves on its own without intervention.
Choice B rationale
Transient strabismus, or the temporary crossing of the eyes, is normal in newborns due to underdeveloped eye muscles and usually resolves as the infant grows.
Choice C rationale
Caput succedaneum is the swelling of the scalp caused by pressure during delivery. It is usually benign and resolves within a few days without treatment.
Choice D rationale
Generalized petechiae, or small red or purple spots on the skin, can indicate a serious underlying condition such as a clotting disorder or infection and requires immediate medical evaluation.
Correct Answer is D
Explanation
Choice A rationale
A respiratory rate of 34/min is within the normal range for a newborn, which is typically between 30 to 60 breaths per minute. This does not indicate immediate distress.
Choice B rationale
Acrocyanosis, or bluish discoloration of the hands and feet, is common in newborns and usually resolves within the first few days of life. It is not a sign of critical illness.
Choice C rationale
Caput succedaneum, a swelling of the soft tissues of the newborn's scalp, is a common and benign condition that resolves on its own within a few days. It does not require immediate medical attention.
Choice D rationale
An axillary temperature of 36°C (96.8°F) is considered low and may indicate hypothermia in a newborn. Hypothermia can lead to serious complications, so this newborn requires immediate assessment and intervention to stabilize their body temperature.
