Question

Quizplus · Accepted Answer

A drug that causes the heart to beat stronger and faster would increase sympathetic activity and mimic the effects of the sympathetic nervous system, thus it would be classified as a sympathomimetic drug. Choices A and C are incorrect because they would either block or decrease sympathetic activity, which is the opposite effect of what the drug in question is expected to do. Choice D is incorrect because anticholinergic drugs work by blocking the neurotransmitter acetylcholine, which is not directly related to sympathomimetic effects.
