Hypotension
question
Which intervention is most appropriate for the treatment of a patient in asystole?
answer
Epinephrine
question
You arrive on the scene with the code team. High-quality CPR is in progress. An AED has previousy advised "no shock indicated." A rhythm check now finds asystole. After resuming high-quality compressions, which action do you take next?
answer
Establish IV or IO access
question
A monitored patient in the ICU developed a sudden onset of narrow-complex tachycardia at a rate of 220/min.

answer
Perform electrical cordioversion
question
A patient with STEMI has ongoing chest discomfort. Heparin 4000 units IV bolus and a heparin infusion of 1000 units per hour are being administered. The patient did not take aspirin because he has a history of gastritis, with was treated 5 years ago. What is your next action?
