Which of the following symptoms is NOT typically observed in a patient suffering from pneumonia?

In a patient suffering from pneumonia, common symptoms include fever, shortness of breath, and chest pain. These symptoms occur as the body responds to the infection within the lungs. Fever is a typical response indicating the presence of an infection, while shortness of breath may arise due to inflammation and fluid buildup in the air sacs, impairing gas exchange. Chest pain can occur as a result of coughing or inflammation of the lung lining.

Increased appetite is not a symptom associated with pneumonia. In fact, patients may experience a loss of appetite due to illness, fever, and general malaise, which are common during infections. This overall decrease in appetite is a typical physiological response as the body focuses its energy on fighting off the infection rather than seeking food intake.
