ACLS Principles Quiz 2

1. A witnessed drowning event should prompt immediate rescue breathing rather than compressions. 

2. After an AED delivers a shock to the patient, the next rhythm check is performed after:

3. An older woman is found down and unresponsive. No bystanders are present. She is not breathing, and no pulse is palpable. Chest compressions are started immediately with rescue breaths. An AED is found, the pads are placed, and it detects a shockable rhythm, which is quickly delivered. Immediate resumption of chest compressions is started. However, upon the next pulse check, there is no palpable pulse. Repeat AED evaluation no longer detects a shockable rhythm. What stage of arrest is the patient most likely in at this time? 

4. An older woman is found unresponsive. She is not breathing and no pulse is palpable. No bystanders are present. Chest compressions are started immediately with rescue breaths. An AED is found and detects a shockable rhythm. The shock is delivered. Chest compressions are immediately resumed. However, following these cycles, there is still no palpable pulse. Repeat AED evaluation no longer detects a shockable rhythm. What is the most likely stage of arrest of the patient? 

5. How does a rescuer provide ventilations on an intubated patient in a multiple rescuer scenario?

6. If an intravenous or intraosseous line cannot be established, the last resort for drug delivery is: 

7. Of the following timeframes, which is the best time to administer epinephrine to a patient in a nonshockable cardiac arrest so that the chance of survival is increased? 

8. Studies show that there is an increased incidence of ROSC, a greater chance of survival to hospital discharge, and improved neurologic outcomes if epinephrine is given within how many minutes after the onset of cardiac arrest?

9. The patient with this rhythm has no pulse and no respirations. He is attached to a biphasic monitor. The first step in treatment is to:
