Which of the following medications stimulates the sympathetic nervous system?
Show answer and explanation
Correct answer: A. Albuterol
- A. Correct. Albuterol is a beta-2 adrenergic agonist, directly stimulating sympathetic (adrenergic) receptors to cause bronchodilation.
- B. Atropine is an anticholinergic (antimuscarinic) agent that blocks parasympathetic activity rather than directly stimulating sympathetic receptors.
- C. Metoprolol is a beta-blocker, which blocks (not stimulates) sympathetic beta receptors.
- D. Diazepam is a benzodiazepine acting on GABA receptors, unrelated to direct sympathetic stimulation.
