Final answer:
Epinephrine is dosed at 2-10 mcg/min for post-arrest blood pressure maintenance to achieve at least 90 mmHg systolic. This dose may be titrated to the patient's response under guidelines from the American Heart Association.
Step-by-step explanation:
The correct dosage of epinephrine for post-arrest blood pressure maintenance to achieve a systolic blood pressure of at least 90 mmHg is B) 2-10 mcg/min. Epinephrine is administered as a continuous intravenous infusion and the dose can be adjusted based on the individual patient's response. For adult advanced cardiovascular life support, per the American Heart Association guidelines, doses for post-cardiac arrest care may need to be titrated to the desired effect on blood pressure and heart rate, while also monitoring for potential side effects.
