Infection in the lungs that can obstruct the airways and cause shortness of breath, chest tightness, diminished breath sounds, and cough is most consistent with which condition?

• A. Pneumonia
• B. Meningitis
• C. Epiglottitis
• D. Congestive Heart Failure

Answer: (A)

Pneumonia is an infection of the lung tissue that causes inflammation and buildup of secretions in the airways. This can obstruct small airways and impair gas exchange, leading to shortness of breath and chest tightness. As the infected areas consolidate, breath sounds over the affected region are often diminished or absent. A cough is a hallmark of lung infection as the body attempts to clear mucus and debris. The other options don’t fit because they involve different locations or processes: epiglottitis affects the upper airway and presents with stridor, drooling, and severe distress rather than a primary lung infection; meningitis is a brain/spinal fluid infection with fever, neck stiffness, and altered mental status; congestive heart failure is a circulatory problem causing fluid buildup and crackles, not an infectious process in the lungs.
