Which of the following is NOT a sign of altered mental status?

High fever is not a direct sign of altered mental status. While it can be associated with conditions that may cause altered mental states, such as infections or other illnesses, a high fever itself indicates a physiological response rather than a cognitive alteration. Signs of altered mental status typically reflect changes in cognitive function or awareness, such as confusion, disorientation, and memory loss, which involve the individual's mental processing and responsiveness to their environment. Thus, while fever may accompany altered mental status, it does not represent a cognitive symptom on its own.
