Which of the following is a common indicator of infection?

• A. Elevated blood pressure
• B. Increased appetite
• C. Fever
• D. Decreased heart rate

Answer: (C)

Fever is a common indicator of infection as it represents the body's natural response to invading pathogens. When the immune system detects an infection, it often triggers a rise in body temperature as a defense mechanism. This increase in temperature can help inhibit the growth of bacteria and viruses, making it more challenging for these pathogens to proliferate. Additionally, fever is frequently accompanied by other symptoms of infection, such as chills, sweating, and malaise, further reinforcing its role as a key sign that something is amiss within the body. In contrast, options like elevated blood pressure may be associated with various conditions, including stress or pain, but it is not a specific indicator of infection. Increased appetite is generally not a sign of infection; typically, individuals may experience a decreased appetite when ill. Lastly, a decreased heart rate is not commonly linked to infections, as infections often lead to an increased heart rate due to the body's stress response. Therefore, fever clearly stands out as a primary and recognized indicator of infection.
