Which assessment finding is a potential sign of complications when a client is receiving oxytocin?

Uterine hyperstimulation is recognized as a potential complication when a client is receiving oxytocin. This occurs when there are excessive contractions of the uterus that can lead to decreased blood flow and oxygen supply to the fetus, potentially resulting in fetal distress. It is critical to monitor the frequency and intensity of contractions during intravenous administration of oxytocin to ensure that they remain within safe limits. If contractions become too frequent or too strong, it can disrupt the normal labor process and may necessitate immediate medical intervention.

In contrast, a fetal heart rate above 160 bpm may suggest fetal tachycardia, which could be concerning but is not specific to oxytocin and may have many other causes. Labor progressing at 3 cm per hour can be considered normal, as progression rates can vary among individuals. Fever with chills could indicate an infection or other underlying condition, though it is not a direct complication of oxytocin administration. Overall, uterine hyperstimulation is the most direct and concerning assessment finding related to the use of oxytocin, which is why it is identified as the correct answer.
