AHA ACLS Written Test Exam 2022/2023 with complete solution

You find an unresponsive pt. who is not breathing. After activating the emergency response system, you determine there is no pulse. What is your next action? - ANSWER Start chest compressions of at least 100 per min. You are evaluating a 58 year old man with chest pain. The BP is 92/50 and a heart rate of 92/min, non-labored respiratory rate is 14 breaths/min and the pulse O2 is 97%. What assessment step is most important now? - ANSWER Obtaining a 12 lead ECG. What is the preferred method of access for epi administration during cardiac arrest in most pts? - ANSWER Peripheral IV An AED does not promptly analyze a rythm. What is your next step? - ANSWER Begin chest compressions. You have completed 2 min of CPR. The ECG monitor displays the lead below (PEA) and the pt. has no pulse. You partner resumes chest compressions and an IV is in place. What management step is your next priority? - ANSWER Administer 1mg of epinepherine During a pause in CPR, you see a narrow complex rythm on the monitor. The pt. has no pulse. What is the next action? - ANSWER Resume compressions What is acommon but sometimes fatal mistake in cardiac arrest management? - ANSWER Prolonged interruptions in chest compressions. Which action is a componant of high-quality chest comressions? - ANSWER Allowing complete chest recoil Which action increases the chance of successful conversion of ventricular fibrillation? - ANSWER Providing quality compressions immediately before a defibrillation attempt. Which situation BEST describes PEA? - ANSWER Sinus rythm without a pulse What is the best strategy for perfoming high-quality CPR on a an advanced airway in place? - ANSWER Provide continuous chest compressionswithout pauses and 10 ventilations per minute. 3 min after witnessing a cardiac arrest, one memeber of your team inserts an ET tube while another performs continuous chest comressions. During subsequent bentilation, you notice the presence of a wavefom on the capnogrophy screen and a PETCO2 of 8 mm Hg. What is the significance of this finding? - ANSWER Chest compressions may not be effective. The use of quantitative capnography in intubated pt's does what? - ANSWER Allowsfor monitoring CPR quality For the past 25 min, EMS crews have attemptedresuscitation of a pt who originally presented with V-FIB. 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? - ANSWER Consider terminating resuscitive efforts after consulting medical control. Which is a safe and effective practice within the defibrillation sequence? - ANSWER Be sure O2 is NOT blowing over the pt's chest during 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? - ANSWER Begin chest compressions. What is an advantage of using hands-free d-fib pads instead of d-fib paddles? - ANSWER Hands-free allows for more rapid d-fib. What action is recommended to help minimize interruptions in chest compressions during CPR? - ANSWER Continue CPR while charging the defibrillator. Which action is included in the BLS survey? - ANSWER Early defibrillation Which drug and dose are recommended for the management of a pt. in refractory V-FIB? - ANSWER Amioderone 300mg What is the appropriate intervalfor an interruption in chest compressions? - ANSWER 10 seconds or less Which of the following is a sign of effective CPR? - ANSWER PETCO2 = or > 10mm Hg What is the primary purpose of a medical emergency team or rapid response team? - ANSWER Identifying and treating early clinical deterioration. Which action improves the quality of chest compressions delivered during resuscitave attemepts? - ANSWER Shitch providers about every 2 min or every 5 compression cycles. What is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse
