ACCS Practice Exam 2025 – Complete Test Preparation Guide

In the case of significant bradycardia following sedation, discontinuing the sedative agent, such as propofol, is the most appropriate initial intervention. Propofol is known to cause cardiovascular effects, including hypotension and bradycardia, particularly when used in higher doses or in sensitive patients. By stopping the drug, the healthcare provider can allow the patient's cardiovascular system to stabilize and potentially reverse the bradycardia.

Reducing oxygen flow is not an appropriate intervention as it does not address the underlying issue of bradycardia. Instead, maintaining adequate oxygenation is critical in any patient experiencing bradycardia, especially post sedation.

Administering IV dopamine may be considered later if the bradycardia persists and is symptomatic. Dopamine can help to increase heart rate and improve hemodynamics, but it's typically not the first step; addressing the cause by discontinuing the sedation is prioritized.

Initiating IV midazolam is also not suitable in this scenario, as benzodiazepines can further depress the central nervous system and exacerbate bradycardia. Midazolam, like propofol, is a sedative and continuing or adding such agents would not help in managing bradycardia.

Therefore
