What is the best action for a nurse to take when monitoring a client receiving terbutaline with increased heart rates?

When a client is receiving terbutaline and exhibits increased heart rates, contacting the physician is the best course of action. Terbutaline is a bronchodilator often used to manage asthma or other respiratory conditions, but it can also lead to side effects such as tachycardia. Increased heart rates may signal a potentially serious response, such as exacerbation of cardiovascular issues or excessive stimulation from the medication.

In this context, it is essential to inform the physician promptly to determine the appropriate intervention. The physician may reconsider the medication dosage, suggest an alternative treatment, or implement additional monitoring strategies to ensure the client's safety and well-being. Proper medical guidance is crucial, especially when adverse effects like increased heart rates are observed.

While monitoring the client is important, and documentation is also necessary, neither action alone is sufficient in this scenario without informing the physician about the adverse effect. Increasing the infusion rate is inappropriate and could heighten the risks associated with terbutaline's side effects. Therefore, the appropriate response involves proactive communication with the healthcare provider.
