Initial symptoms of pulmonary TB are best described by which of the following?

• A. Dry cough that becomes productive, fatigue, malaise, anorexia, and low-grade fever.
• B. Sudden chest pain and hemoptysis
• C. Severe shortness of breath only
• D. Fever only without cough

Answer: (A)

Pulmonary TB tends to start with a gradual, persistent cough that often begins dry and later becomes productive as inflammation in the lungs progresses. This is usually accompanied by systemic, nonspecific symptoms such as fatigue, malaise, loss of appetite (anorexia), and a low-grade fever, reflecting the body's ongoing immune response to the infection. These features typically persist for weeks to months, not as a sudden onset. While hemoptysis and chest pain can occur, they are not the hallmark of early presentation and are less common initially. Severe shortness of breath is not a typical early finding because TB primarily causes a chronic inflammatory process rather than acute respiratory failure. Fever may be present, but it is not usually the sole symptom; the cough with constitutional symptoms best captures the initial picture.
