Question 1 of 5
What is the primary purpose of using terbutaline in labor for intrauterine resuscitation?
Correct Answer: B
Rationale: The primary purpose of using terbutaline in labor for intrauterine resuscitation is to improve placental blood flow. Terbutaline is a beta-2 adrenergic agonist that causes vasodilation in the uterine arteries, leading to increased blood flow to the placenta. This helps enhance oxygen and nutrient delivery to the fetus, thereby improving fetal well-being. Stimulating uterine contractions (choice
A) is not the main purpose of terbutaline in this context. Decreasing fetal heart rate variability (choice
C) is not a goal of terbutaline use. Preventing preterm labor (choice
D) is not directly related to the use of terbutaline for intrauterine resuscitation.
