You have completed 2 minutes of CPR. The ECG monitor displays the lead II rhythm below, and the patient has no pulse. Another member of your team resumes chest compressions, and an IV is in place. What management step is your next priority?
Give 0.5 mg of atropine.
Insert an advanced airway.
Administer a dopamine infusion.
The Correct Answer and Explanation is:
Correct Answer: Insert an advanced airway.
Explanation:
When a patient is in cardiac arrest with no pulse, and two minutes of CPR have already been performed, it is critical to follow the Advanced Cardiac Life Support (ACLS) guidelines for the appropriate next step.
The ECG monitor shows a rhythm, but since the patient is pulseless, the situation is consistent with pulseless electrical activity (PEA) or asystole. The first step—already taken—is to resume high-quality CPR immediately and ensure that IV/IO access is established. This has been done in this scenario.
After high-quality CPR and IV access, the next priority includes:
Why “Insert an advanced airway” is correct:
Once CPR and IV access are established, the next priority in managing a cardiac arrest is often to optimize oxygenation and ventilation. Inserting an advanced airway (like an endotracheal tube or supraglottic airway) ensures that the lungs are properly ventilated and oxygen delivery to vital organs is maximized. It also allows for continuous chest compressions without interruption for breaths, increasing the efficiency of CPR.
Why the other options are incorrect:
Summary:
The priority after initiating CPR and IV access is to optimize airway and ventilation—thus, inserting an advanced airway is the next best step.
