NCLEX Question of the Day
Physiological Adaptation QID 1085
A patient with chronic obstructive pulmonary disease (COPD) is prescribed albuterol. What is the primary mechanism of action of this medication?
Explanation
Albuterol is a short-acting beta-2 adrenergic agonist. It works by stimulating beta-2 receptors in the bronchial smooth muscle, leading to bronchodilation. This action helps to relieve symptoms of bronchospasm in patients with conditions like COPD and asthma, improving airflow and reducing respiratory distress.
Albuterol does not increase mucous production, decrease the inflammatory response, or block acetylcholine receptors. Its primary function is to relax bronchial muscles, making it easier for the patient to breathe.
