What is the primary use of terbutaline in obstetric care?

• A. To expedite labor
• B. As a tocolytic agent
• C. To manage hypertension
• D. To prevent hemorrhage

Answer: (B)

Terbutaline is primarily used in obstetric care as a tocolytic agent, which means it is administered to help suppress premature labor and delay delivery. Tocolytic agents like terbutaline work by relaxing the uterine muscles, thereby decreasing the frequency and intensity of contractions. This can be essential in situations where extending the pregnancy is critical for fetal development, as early delivery can lead to complications for the neonate. While terbutaline may influence labor dynamics by potentially slowing contractions, its main role as a tocolytic distinguishes it from the other uses presented in the question. The other options do not align with terbutaline's primary function in this specific clinical context.
