A nurse is caring for a client who is at 28 weeks of gestation and received terbutaline. Which of the following findings should the nurse expect?

A. Fetal heart rate 100/min: This fetal heart rate is below the normal range (110–160 bpm) and may indicate fetal bradycardia. Terbutaline typically causes a transient increase in fetal heart rate due to its beta-adrenergic effects, not a decrease. This finding would therefore not be expected. B. Weakened uterine contractions: Terbutaline is a beta-2 adrenergic agonist used as a tocolytic to relax smooth muscles, including the uterus. It decreases the frequency and intensity of uterine contractions, which is the intended therapeutic effect in managing preterm labor at 28 weeks' gestation. C. Enhanced production of fetal lung surfactant: Surfactant production is more directly stimulated by corticosteroids like betamethasone, not terbutaline. While both medications may be used together in preterm labor, terbutaline's role is to delay labor not to enhance fetal lung maturity. D. Maternal blood glucose 63 mg/dL: Terbutaline may cause maternal hyperglycemia, not hypoglycemia. It stimulates glycogenolysis and gluconeogenesis, leading to increased blood glucose levels. A glucose level of 63 mg/dL is below normal and not typically associated with terbutaline use.
