ACLS Exam Version A (50 Questions And Answers100% Verified A+ graded latest update)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? Correct ans - start chest compressions at a rate of at least 100/min. 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? Correct ans - obtaining 12-lead ecg. what is the preferred method of access for epinephrine administration during cardiac arrest in most patients? Correct ans - peripheral intravenous An activated AED does not promptly analyze the rhythm. What is your next action? Correct ans - begin chest compressions. You have completed 2 min of CPR. The ECG monitor displays the lead below and the pt. has no pulse. another member resumes chest compressions and an IV is in place. What management step is your next priority? Correct ans - administer one mg of epinephrine During a pause in CPR, you see this lead II ECG rhythm on the monitor. The patient has no pulse. What is the next action? Correct ans - resume chest compressions what is a common but sometimes fatal mistake in cardiac arrest management? Correct ans - prolonged interruptions of chest compressions what action is a component of high-quality chest compressions? Correct ans - uninterrupted compressions at a depth of 1 1/2 inches Which action increases the chance of successful conversion of ventricular fibrillation? Correct ans - ventricular tachycardia with a pulse which situation BEST describes pulseless electrical activity? Correct ans - sinus rhythm without a pulse What is the best strategy for perfoming high-quality CPR on a an advanced airway in place? Correct ans - provide continuous chest compressions without pauses and 10 ventilations per minute. 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 capnography screen and a PETCO2 level of 8 mm Hg. What is the significance of this finding? Correct ans - chest compressions may not be effective the use of quantitative capnography in intubated patients Correct ans - allows for monitoring of cpr quality For the past 25 min, EMS crews have attempted resuscitation of a pt who originally presented with ventricular fibrillation. After the 1st shock, the ECG screen displayed asystole, which has persisted despite 2 doses of epi, a fluid bolus, and high quality CPR. What is your next treatment? Correct ans - consider terminating resuscitative efforts after consulting medical control. Which is a safe and effective practice within the defibrillation sequence? Correct ans - be sure oxygen is now blowing over the patient's chest during the shock During your assessment, your pt suddenly loses consciousness. After calling for help and determining that the pt. is not breathing, you are unsure whether the pt. has a pulse. What is your next action? Correct ans - Begin chest compressions what is the advantage of using hands-free defibrillation pads instead of defibrillation paddles? Correct ans - hands-free pads allow for a more rapid defibrillation What action is recommended to help minimize interruptions in chest compressions during CPR?
