Final answer:
The nurse should withhold the next dose of terbutaline sulfate if the client experiences cardiac arrhythmias or tachycardia.
Step-by-step explanation:
Based on the given information, the nurse should withhold the next dose of terbutaline sulfate if the client experiences cardiac arrhythmias or tachycardia.
Terbutaline sulfate is a medication used to treat preterm labor by relaxing the uterine muscles. However, it can also have side effects on the cardiovascular system, such as increasing heart rate or causing irregular heart rhythms. Therefore, if the nurse observes any abnormal cardiac findings, it is important to withhold the next dose and consult the healthcare provider for further guidance.
