sinus tachycardia. The closest appropriate hospital is 40 miles
away. Which of the following is the MOST appropriate next
action?

B) Begin an infusion of dopamine.
C) Perform a head-to-toe exam.

auscultation of her lungs reveals diffuse coarse crackles. Which
of the following treatment interventions is MOST appropriate
for this patient?
A) Dopamine, 2 to 20 mcg/kg/min
