Final answer:
A nurse will monitor for fetal distress while a woman is receiving oxytocin, particularly indicated by a low fetal heart rate, such as 84 bpm, which could necessitate emergency birth procedures. The correct answer is c). This can be a cause for emergency intervention.
Step-by-step explanation:
The nurse will monitor a woman receiving oxytocin (Pitocin) for fetal distress, which can be indicated by abnormalities in the fetal heart rate. An abnormality that would be particularly concerning is a fetal heart rate of 84 bpm (option c), which is lower than normal and may suggest that the fetus is not getting enough oxygen due to overly powerful or prolonged contractions. This can be a cause for emergency intervention.
