Accepted Answer

Discontinue all heparin and switch to argatroban or bivalirudin

Question 2

Which reversal agent is used for suspected opioid overdose during air medical transport?

Accepted Answer

Naloxone

Question 3

What is the correct IV loading dose of amiodarone for a hemodynamically stable patient with ventricular tachycardia?

A diabetic patient transported by air has a blood glucose of 38 mg/dL and is unconscious. There is no IV access. What is the best immediate treatment?

Accepted Answer

Glucagon 1 mg IM
