Multiple Choice

A 45-year-old female complains of a fever, shortness of breath, and coughing up thick, red sputum. You should suspect?

Blood in the sputum with fever points toward pulmonary tuberculosis among common respiratory infections. TB often causes a productive cough with low-grade or fluctuating fever, and as the disease involves lung tissue, bleeding into the airways can produce blood-tinged (red) sputum. This pattern helps distinguish it from sinusitis, which rarely causes productive cough with blood, and from bronchitis, which may produce mucus but not typically blood. While pneumonia can also cause fever and productive cough, the presence of blood-tinged sputum seen here leans toward TB as the likely cause in this context.
