Quizplus · Accepted Answer

A F1F1F1S1F1F1F10₂-adrenergic agonist, such as albuterol, is a commonly used bronchodilator that relaxes the smooth muscles in the airways and helps to alleviate an asthmatic attack. The other options are not as effective or may even worsen the condition. Pulmonary surfactant is used to treat respiratory distress syndrome in premature infants. Muscarinic agonists, such as pilocarpine, actually constrict the airways and can worsen asthma symptoms. Histamine can trigger asthma attacks and a F1F1F1S1F1F1F10₂-adrenergic antagonist, such as propranolol, can actually cause bronchoconstriction.
