Uterine tachysystole during oxytocin administration requires what first action?

• A. Stop oxytocin infusion
• B. Administer tocolytic
• C. Increase oxytocin
• D. Apply external fetal monitoring

Answer: (D)

When contractions become excessive from oxytocin, the priority is to remove the stimulus causing the hyperstimulation. The first action is to discontinue the oxytocin infusion. Stopping the drug halts further stimulation, which helps the uterus relax and improves placental blood flow to protect fetal well-being. After stopping oxytocin, continue to monitor the fetus closely, place the patient in a left lateral position to optimize circulation, and administer supportive measures such as supplemental oxygen and IV fluids as indicated. If contractions remain high despite stopping oxytocin, a clinician may use a tocolytic to reduce uterine activity. The key point is that stopping the oxytocin is the essential initial step to counter tachysystole.
