An elderly male in cardiac arrest has been shocked by the AED. After 2 minutes of CPR, the rhythm is reanalyzed and no shock is advised. The patient has a weak carotid pulse and signs of movement. The next action is to:

• A. Transport immediately without further assessment
• B. Start IV fluids and continue CPR only
• C. Administer a pharmacologic agent
• D. Reassess airway and breathing and treat accordingly

Answer: (D)

When a defibrillation attempt and CPR have been performed and a return of circulation is evidenced (even if the pulse is weak) the priority shifts to securing and supporting ventilation. A pulse means chest compressions are no longer the immediate need; you must ensure the patient can oxygenate and ventilate effectively. Reassess airway patency, deliver oxygen, and provide assisted ventilation as needed (for example, with a bag-valve-mask or advanced airway if indicated). Monitor breathing and pulse continuously and manage any airway obstruction or hypoxia.

This is why the action focuses on airway and breathing first. The other options skip the essential step of ensuring adequate ventilation when a pulse has returned, and they either advocate continuing chest compressions without a pulse, giving fluids or drugs without indication, or bypassing airway management in favor of transport.
