response system, you determine there is no pulse. What is your next action? 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? Obtaining a 12 lead ECG. What is the preferred method of access for epi administration during cardiac arrest in most pts? Peripheral IV An AED does not promptly analyze a rythm. What is your next step? 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? 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? Resume compressions What is acommon but sometimes fatal mistake in cardiac arrest management? Prolonged interruptions in chest compressions. Which action is a componant of high-quality chest comressions? Allowing complete chest recoil Which action increases the chance of successful conversion of ventricular fibrillation? Providing quality compressions immediately before a defibrillation attempt. Which situation BEST describes PEA? Sinus rythm without a pulse What is the best strategy for perfoming high-quality CPR on a pt.with an advanced airway in place? Provide continuous chest compressionswithout pauses and 10 ventilations per minute. 3 min after witnessing a cardiac arrest, one member of your team inserts an ET tube while another performs continuous chest comressions. During subsequent ventilation, you notice the presence of a wavefom on the capnogrophy screen and a PET CO2 of 8 mm Hg. What is the significance of this finding? Chest compressions may not be effective. The use of quantitative capnography in int
