Advanced Cardiovascular Life Support (ACLS) Practice Exam

After return of spontaneous circulation, which of the following is NOT a recommended action?

1. Maintain O2 saturation at 94%

2. Continue CPR

3. Administer fluids or vasopressor for hypotension

4. Perform a 12 lead ECG

The correct answer is: Continue CPR

Continuing CPR after the return of spontaneous circulation (ROSC) is not a recommended action because the primary goal during resuscitation is to restore effective circulation and ensure that the heart has returned to a stable rhythm. Once ROSC is achieved, the focus shifts to optimizing perfusion and maintaining hemodynamic stability. The recommended actions following ROSC include maintaining adequate oxygen saturation, which should ideally be above 94% to ensure that the brain and vital organs receive sufficient oxygen. Administering fluids or vasopressors is crucial for treating hypotension, which may occur after ROSC due to various factors such as hypovolemia or the effects of resuscitation itself. Performing a 12-lead ECG is also important post-ROSC to assess for any underlying cardiac issues or ischemia that may have caused the cardiac arrest. These actions are aimed at stabilizing the patient's condition and preventing further complications, whereas continuing CPR would be unnecessary and potentially harmful after adequate circulation has been restored.
