What physiological response can indicate a fever?

The indication of a fever can be observed through an increased heart rate and an elevated body temperature. When the body experiences a fever, it is often part of an immune response to infection or illness. The hypothalamus, which regulates body temperature, raises the set point in response to pyrogens.

As the body temperature rises, it often triggers the heart to pump faster to maintain blood circulation and facilitate the transport of immune cells to areas of infection. This correlation between an elevated temperature and an increased heart rate is a physiological response that reflects the body’s effort to combat whatever is causing the fever.

Therefore, the choice that highlights both the increased heart rate and the increased body temperature accurately reflects this response. It is essential to monitor these changes during clinical assessments, as they provide valuable information about the patient’s condition and readiness to respond to treatment or interventions.
