Which procedure may be performed in the Emergency Department?

• A. Defibrillation
• B. Dialysis
• C. Electroconvulsive Therapy
• D. CPR

Answer: (D)

In emergency medicine, immediate life support is provided through CPR to treat patients in cardiac or respiratory arrest. CPR combines chest compressions to keep blood flowing with airway management and breath support, and it is started right away to preserve brain and heart function while more definitive care is arranged. Dialysis is a kidney replacement therapy and is not typically initiated in the ED unless there are specific urgent needs; electroconvulsive therapy is a psychiatric treatment not performed in the ED; defibrillation is used during resuscitation when a shockable rhythm is present, but CPR is the foundational procedure that can be applied in any arrest scenario and is routinely performed in the Emergency Department.
