After cardioversion, what is the first nursing action regarding the patient's condition?

Following cardioversion, the priority nursing action is to ensure a patent airway and administer oxygen. This is critical because the patient may be at risk for respiratory complications due to the sedation used during the procedure or the underlying cardiac condition. By securing the airway, the nurse can help prevent hypoxia and ensure the patient receives adequate oxygenation.

Monitoring the airway is especially important in a cardiac event, as issues such as decreased consciousness or respiratory depression can occur post-procedure. Administering oxygen further supports the patient's respiratory needs and maintains proper oxygen saturation levels, which is essential for recovery and overall cardiovascular function.

While checking vital signs and documenting the procedure are also important components of post-cardioversion care, they follow the immediate need to ensure the patient is stable and adequately oxygenated. Addressing airway concerns takes precedence as it directly impacts the patient's safety and well-being in the immediate aftermath of the procedure.
