A 23-year-old woman presents with a productive cough, malaise, difficulty breathing, and wheezing. The nurse practitioner diagnoses her with acute bronchitis and knows that which of the following describes the pathophysiology of this disease process?
Explanation & Rationale
Choice A reason: Acute bronchitis is most commonly caused by viral infections that trigger inflammation of the bronchial walls. This leads to mucosal thickening, epithelial damage, and increased mucus production, resulting in cough and wheezing. The epithelial injury contributes to the symptoms and transient airflow limitation. Choice B reason: This describes emphysema, a chronic condition involving destruction of alveolar walls and irreversible airflow obstruction. Acute bronchitis does not involve alveolar destruction. Choice C reason: This describes asthma, which involves chronic inflammation, mucus plugging, and bronchial smooth muscle contraction. While bronchitis may cause wheezing, it does not involve the same pathophysiologic mechanisms. Choice D reason: This describes acute respiratory distress syndrome (ARDS), which involves alveolar-capillary membrane damage and fluid leakage. It is a severe condition unrelated to the typical presentation of acute bronchitis.
