Which signs are typical of pneumonia?

• A. History of respiratory infection, fever, productive cough (rust colored or greenish mucus), possibly some wheezing, chest discomfort or chest pain
• B. Sudden onset of fever and chills with severe headache
• C. Pleuritic chest pain with leg swelling
• D. Pursed lip breathing and cyanosis

Answer: (A)

Respiratory infection with lung inflammation leads to fever, a productive cough, and chest discomfort, which are classic signs of pneumonia. The productive cough with colored sputum—rust-colored or greenish mucus—reflects infection of the airways and alveoli, where inflammatory cells and bacteria mix in the sputum. Wheezing can occur from airway irritation, and chest pain or discomfort often appears due to inflammation of the pleura and the effort of coughing. Together, these signs point to a lung infection rather than a problem isolated to the upper airway or another organ system. Other scenarios describe conditions that don’t fit the typical lung-infection pattern as neatly. A sudden fever with severe headache can point to meningitis or another systemic illness, not primarily pneumonia. Chest pain with leg swelling suggests a pulmonary embolism rather than an infectious process in the lungs. Pursed-lip breathing and cyanosis indicate severe respiratory distress or an underlying chronic lung disease like COPD, rather than the more common pneumonia presentation.
