Question

which of the following is a short-acting sympathomiometic agent indicated for rescue treatment of asthma? tiotropium theophylline albuterol sulfate ipatropium bromide

Explanation:

To determine the correct answer, we analyze each option:

• Tiotropium: A long - acting anticholinergic, not a short - acting sympathomimetic, and not for rescue asthma treatment.
• Theophylline: A bronchodilator with a longer onset and not a short - acting sympathomimetic for rescue.
• Albuterol sulfate: A short - acting β₂ - adrenergic agonist (sympathomimetic) used for rescue treatment of asthma due to its rapid onset of action.
• Ipatropium bromide: An anticholinergic, not a sympathomimetic.

Answer:

Albuterol sulfate
