A client in preterm labor is administered terbutaline sulfate (Brethine). Which assessment should be prioritized during administration?

The priority assessment during the administration of terbutaline sulfate, a tocolytic agent used to manage preterm labor, is monitoring the maternal and fetal heart rates. Terbutaline can cause significant cardiovascular effects, including tachycardia in both the mother and the fetus due to its beta-adrenergic agonist properties. It is crucial to assess both heart rates to identify any potential adverse reactions or the effects of the medication.

Monitoring maternal heart rate helps in assessing the mother's response to the medication and identifying any side effects like palpitations or excessive tachycardia. Additionally, evaluating the fetal heart rate is essential to ensure that the fetus is not experiencing any distress or adverse effects from the medication.

While maternal blood pressure and respirations, hourly urinary output, and deep tendon reflexes are also important assessments in monitoring the overall health and response to medication, the direct and immediate effects of terbutaline on heart rates make them the priority during administration. Keeping a close eye on both maternal and fetal heart rates ensures that any adverse reactions can be promptly addressed, thus promoting the safety and well-being of both mother and child.
