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.

Answer and Explanation

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 A

Explanation

Choice A rationale

Irregular heartbeat (palpitations or arrhythmias) can indicate a serious cardiovascular side effect of nifedipine. It requires immediate medical attention as it could compromise maternal and fetal circulation.

Choice B rationale

Hair loss is not a known adverse effect of nifedipine and generally does not pose a significant health risk. It is more commonly associated with hormonal changes rather than medication side effects.

Choice C rationale

Increased salivation is not a common side effect of nifedipine. Nifedipine primarily affects the cardiovascular system rather than salivary glands.

Choice D rationale

Pause is not a recognized adverse effect related to nifedipine usage. The term itself is ambiguous and not typically associated with the pharmacological profile of nifedipine.

A. Respiratory rate 12/min. B. Absent deep tendon reflexes. C. Slurred speech. D. Urine output 22 mL/hr.

Correct Answer is A

Explanation

Choice A rationale

A respiratory rate of 12/min indicates that the respiratory depression caused by magnesium sulfate toxicity has been effectively reversed by calcium gluconate. Normal respiratory rate in adults is 12-20 breaths per minute.

Choice B rationale

Absent deep tendon reflexes indicate ongoing magnesium sulfate toxicity. Calcium gluconate administration should restore normal reflexes, not cause their absence.

Choice C rationale

Slurred speech is a sign of magnesium sulfate toxicity. Effective treatment with calcium gluconate should improve neurological function and resolve symptoms like slurred speech.

Choice D rationale

A urine output of 22 mL/hr is below the normal range and suggests renal impairment or ongoing toxicity. Effective treatment should result in an increase in urine output to within the normal range (greater than 30 mL/hr).
