The primary use of a sympathomimetic in emergency medicine is:

a. Oppose the effects of the parasympathetic nervous system
b. Decrease blood pressure and heart rate
c. Increase motility of the digestive tract
d. Increase blood pressure in cardiogenic and septic shock

d
Rationale: a. A sympathomimetic stimulates the effects of the sympathetic nervous system. Although, in opposition to the sympathetic nervous system, a parasympatholytic would be more desirable.
b. Sympathomimetics increase blood pressure and heart rate.
c. A parasympathomimetic would increase motility of the digestive tract.
d. Correct.
