Which symptom is NOT typically associated with pneumonia?

C. Diaphoresis is not typically associated with pneumonia in the same way that the other symptoms are. Pneumonia primarily affects the lungs, causing inflammation and leading to respiratory symptoms. A productive cough, chest pain, and shortness of breath are classic signs of pneumonia as they directly relate to respiratory distress and the presence of fluid or infection in the lungs.

A productive cough occurs as the body attempts to clear mucus and pus out of the airways, while chest pain commonly arises from coughing or pleuritic involvement. Shortness of breath is a common manifestation due to impaired gas exchange and decreased lung capacity caused by the infection.

While diaphoresis, or excessive sweating, can occur in some infections due to systemic effects or fever, it is not a hallmark symptom of pneumonia and can be seen in various other conditions. Thus, it stands out as the symptom least commonly associated directly with pneumonia.
