Which of the following indicates that Terbutaline is being used effectively?

Terbutaline is a medication primarily used as a tocolytic agent to relax the uterus and inhibit premature contractions during labor. When Terbutaline is administered effectively, one of the key indicators is the control of uterine contractions combined with a stable fetal heart rate.

This means that the medication successfully reduces the frequency and intensity of contractions, allowing for a more stable environment for the fetus. In a clinical setting, monitoring these parameters is crucial, as controlled contractions help prevent fetal distress, leading to a safer delivery process. Additionally, a stable fetal heart rate indicates that the fetus is not experiencing stress, which could result from excessive contractions or other complications. Therefore, the presence of controlled contractions alongside a stable heart rate reflects the therapeutic effectiveness of Terbutaline in managing preterm labor.

While increased fetal movement, reduced maternal anxiety, and lowered maternal blood pressure can be positive signs in certain contexts, they do not specifically correlate with the effectiveness of Terbutaline's primary intended use in managing contractions during labor.
