Before synchronized cardioversion, what should the patient have?

• A. Only a monitor
• B. Only vascular access
• C. Both a cardiac monitor and vascular access
• D. Neither

Answer: (C)

Before synchronized cardioversion, you need both a cardiac monitor and vascular access. The monitor is essential to identify the heart’s rhythm and to time the shock correctly to the R wave, ensuring synchronization and reducing the risk of inducing another dangerous rhythm. Establishing IV access is important to deliver any needed medications or sedatives quickly and to manage potential hypotension or complications after the shock. Relying on just one element leaves safety gaps: a monitor without IV access delays meds and airway/comfort management, while IV access without rhythm monitoring makes it impossible to synchronize the shock accurately and monitor the patient’s response.
