Mrs. S with preterm labor will be under Terbutaline (Brethine) therapy. Before beginning the therapy, which of the following assessments would be most important?
参考答案: B
参考解析: Terbutaline, a beta-2 selective adrenergic agonist, is used to suppress labor by relaxing the pregnant uterus. In some cases, its beta-2 selectivity is lost, causing cardiac overstimulation. Generally, the drug is contraindicated for a client with a heart rate greater than 130 beats/minute or any cardiac arrhythmias. Therefore, the nurse would need to assess the client's heart rate.
