During an asthma attack, administering a beta-agonist medication typically results in constriction of the bronchial smooth muscle.
False
True
The statement is false. Beta-agonist medications, such as albuterol, are bronchodilators commonly used during asthma attacks because they cause the airways to widen (bronchodilation), not narrow (constriction). They work by binding to beta-2 adrenergic receptors in the bronchial smooth muscle, which leads to muscle relaxation. This action helps to relieve symptoms of an asthma attack, such as wheezing and shortness of breath. Constriction of the bronchial smooth muscle is the underlying problem during an asthma attack, and bronchodilators work to reverse this.
