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 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? - answer Obtaining a 12 lead ECG. What is the preferred method of access for epi administration during cardiac arrest in most pts?
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 pulseless electrical activity? - answer Sinus rythm without a pulse What is the BEST strategy for performing high-quality CPR on a patient with an advanced airway in place? - 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 PETCO level 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 patients - answer allows for monitoring of CPR quality. For the past 25 minutes, an EMS crew has attempted resuscitation of a patient who originally presented in ventricular fibrillation. After the first shock, the ECG screen displayed asystole, which has persisted despite 2 doses of epinephrine, a fluid bolus, and high-quality CPR. What is your next treatment? - answer Consider terminating resuscitive efforts after consulting medical control.
