Cardiac Arrest and Post-Resuscitation Care Practice Test

You are performing CPR on a 62-year-old female who is intubated. Waveform capnography shows a consistent ETCO2 reading of 25 mmHg. During a compressor switch, the reading suddenly drops to 4 mmHg and remains there despite resumption of high-quality compressions.

You are treating a 34-year-old female in cardiac arrest after an intentional overdose. The monitor shows a PEA with a rate of 50 and a very wide QRS complex. A family member states she took a whole bottle of 'nerve pills'.
