heart rate is 92/min, his nonlabored respiratory rate is 14 breaths/min, and his pulse oximetry reading is
97%. Which assessment step is most important now? - CORRECT ANSWERC) Obtaining a 12-lead ECG.

endotracheal tube while another performs chest compressions. Capnography shows a persistent
waveform and a PETCO2 of 8 mmHg. Which is the significance of this finding? - CORRECT ANSWERA)
Chest compressions may not be effective.
