Correct Answer - C
Answer: C - High dose vasopressin
Vasopressin is an alternative vasopressor at high doses, causes
vasoconstriction by directly stimulating smooth muscle V1
receptors.
American Heart Association (AHA) guidelines states “Vasopressin is
a reasonable first-line vasopressor in patients with ventricular
fibrillation or pulseless ventricular tachycardia. Additionally, the
guidelines comment that one dose of vasopressin 40 U may replace
the first or second dose of epinephrine in all pulseless sudden
cardiac arrest scenarios, including asystole and pulseless electrical
activity
