Which of the following are classic symptoms of tuberculosis (TB)?

The classic symptoms of tuberculosis (TB) include fever, night sweats, and weight loss, which are often associated with the body's response to the infection and the inflammatory processes it triggers. Fever is a common sign of infection, while night sweats can indicate the presence of certain systemic infections like TB, where the body attempts to regulate temperature during the night. Weight loss occurs as a result of the body being in a sustained state of inflammation and stress due to the infection, leading to decreased appetite and metabolic changes.

Other options present symptoms that can be associated with various respiratory or infectious diseases, but they do not encapsulate the hallmark triad of TB symptoms. For instance, options including sore throat, chills, and chest pain might relate to other conditions but do not specifically capture the essence of TB presentations. The combination of fever, night sweats, and weight loss is particularly indicative of TB and is widely recognized in clinical practice and literature.
