Which of the following is a common sign of infection in a patient?

Fever and increased heart rate are indeed common signs of infection in a patient. When the body is fighting off an infection, it often triggers a systemic response known as the acute phase response. This response causes the body temperature to rise, leading to fever as the body attempts to create an environment less conducive to pathogens. Additionally, an increased heart rate is often observed as the heart works harder to circulate more blood, which helps to transport immune cells to the site of infection more efficiently. These physical responses are important indicators that can aid healthcare providers in assessing a patient’s condition and determining the appropriate course of treatment. Other signs of infection may include chills, fatigue, and localized symptoms depending on the site of infection, but fever and tachycardia are some of the most consistently observed systemic symptoms.
