ACLS version A| 50 QUESTIONS| WITH COMPLETE SOLUTIONS 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 answer: 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 answer: obtaining 12-lead ecg. what is the preferred method of access for epinephrine administration during cardiac arrest in most patients? correct answer: peripheral intravenous An activated AED does not promptly analyze the rhythm. What is your next action? correct answer: 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 answer: 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 answer: resume chest compressions what is a common but sometimes fatal mistake in cardiac arrest management? correct answer: prolonged interruptions of chest compressions what action is a component of high-quality chest compressions? correct answer: uninterrupted compressions at a depth of 1 1/2 inches Which action increases the chance of successful conversion of ventricular fibrillation? correct answer: ventricular tachycardia with a pulse which situation BEST describes pulseless electrical activity? correct answer: sinus rhythm without a pulse What is the best strategy for perfoming high-quality CPR on a pt.with an advanced airway in place? correct answer: 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 answer: chest compressions may not be effective the use of quantitative capnography in intubated patients correct answer: 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 answer: consider terminating resuscitative efforts after consulting medical control. Which is a safe and effective practice within the defibrillation sequence? correct answer: 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 answer: Begin chest compressions what is the advantage of using hands-free defibrillation pads instead of defibrillation paddles? correct answer: hands-free pads allow for a more rapid defibrillation What action is recommended to help minimize interruptions in chest compressions during CPR? correct answer: continue CPR while charging the defibrillator what action is included in the bls survey? correct answer: early defibrillation which drug and dose are recommended for the management of a patient in refractory ventricular fibrillation? correct answer: amiodarone 300mg what is the appropriate interval for an interruption in chest compression? correct answer: 10 seconds or less which of the following is a sign of effective CPR? correct answer: PETCO2 greater than or equal to 10mm hg what is the primary purpose of a medical emergency team (MET) or rapid response team (RRT)? correct answer: identifying and treating early clinical deterioration Which action improves the quality of chest compressions delivered during resuscitave attemepts? correct answer: switch providers about every 2 minutes or every 5 compression cycles. what is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse rate of 80/min? correct answer: 1 breath every 5 to 6 seconds
