ACLS version A EXAM 2022

1. you find an unresponsive patient who is not breathing. after activating the emergency response system, you determine that there is no pulse. what is your next action?: start chest compressions at a rate of at least 100/min. 2. you are evaluating a 58-year-old man with chest pain. the blood pressure is 92/50 mm hg, the heart rate is 92/min, the nonlabored respiratory rate is 14 breaths/min, and the pulse oximetry reading is 97%. what assessment step is most important now?: obtaining 12-lead ecg. 3. what is the preferred method of access for epinephrine administration during cardiac arrest in most patients?: peripheral intravenous 4. An activated AED does not promptly analyze the rhythm. What is your next action?: begin chest compressions. 5. You have completed 2 min of CPR. The ECG monitor displays the lead be- low and the pt. has no pulse. another member resumes chest compressions and an IV is in place. What management step is your next priority?: administer one mg of epinephrine 6. During a pause in CPR, you see this lead II ECG rhythm on the monit patient has no pulse. What is the next action?: resume chest compress 7. what is a common but sometimes fatal mistake in cardiac arrest manage- ment?: prolonged interruptions of chest compressions 8. what action is a component of high-quality chest compressions?: uninter- rupted compressions at a depth of 1 1/2 inches 9. Which action increases the chance of successful conversion of ventricular fibrillation?: ventricular tachycardia with a pulse 10. which situation BEST describes pulseless electrical activity?: sinus rhythm without a pulse 11. What is the best strategy for perfoming high-quality CPR on a an advanced airway in place?: provide continuous chest compressions without pauses and 10 ventilations per minute. 12. Three minutes after witnessing a cardiac arrest, one member of your team inserts an endotracheal tube while another performs continuous chest compressions. During subsequent ventilation, you notice the presence of a waveform on the ca
