A patient with fever and pleuritic chest pain and wheezes most likely has which condition?

• A. Pneumonia
• B. Bronchitis
• C. Asthma
• D. Anaphylaxis

Answer: (A)

Fever plus pleuritic chest pain points toward an infectious/inflammatory process involving the lung and pleura, with pneumonia fitting that pattern well. The fever reflects infection, and pleuritic pain arises from inflammation of the pleura as the infection spreads to the pleural surfaces, causing sharp pain that worsens with deep breaths. Wheezes can occur with airway irritation or concurrent bronchospasm, which can be seen in pneumonia, but the combination of fever and pleuritic chest pain makes pneumonia the most likely diagnosis. By comparison, asthma typically presents with episodic wheeze and dyspnea without fever or pleuritic pain; acute bronchitis may cause wheeze and cough but fever with pleuritic chest pain is less typical; anaphylaxis presents with rapid airway compromise and systemic signs rather than a fever and pleuritic chest pain pattern.
