Answer 11

immediately resume CPR

Question 12

If the rhythm is organized and there is a palpable pulse…

proceed to post-cardiac arrest care

Question 13

When IV/IO access is available…

Answer 13

give a vasopressor during CPR

Question 14

The two vasopressors that can be administered are…

Answer 14

Epinephrine

Vasopressin

Question 15

Dose and timing of two vasopressors

Answer 15

Epinephrine - 1 mg IV/IO - repeat every 3 to 5 minutes

Vasopressin - 40 units IV/IO - may substitute for the first or second dose of epinephrine

Question 16

What are the three antiarrhythmics to consider?

Answer 16

Amiodarone
Lidocaine
Magnesium sulfate

Question 17

What is the dose given of Amiodarone?

Answer 17

300 mg IV/IO bolus, then consider an additional 150 mg IV/IO once

Question 18

What is the dose given of Lidocaine? What is the maximum dose? When should Lidocaine be used?

Answer 18

1 to 1.5 mg/kg IV/IO first dose, then 0.5 to 0.75 mg/kg IV/IO at 5- to 10-minute intervals to a maximum dose of 3 mg/kg

Lidocaine should be used if Amiodarone is unavailable
