Which assessment finding would suggest that Stan may have overexerted himself during physical therapy?

Rapid and shallow respirations can indicate that a person has overexerted themselves, particularly during physical therapy or intense physical activity. When the body undergoes physical stress, it demands more oxygen, and the respiratory system responds by increasing the rate of breathing. However, shallow breathing signifies that despite the rapid breathing rate, the depth of each breath is insufficient to meet the increased oxygen demands. This respiratory pattern is a common physiological response to exertion or fatigue, suggesting that Stan may indeed be pushing his limits during therapy sessions.

In contrast, a documented fever may indicate an infection or inflammatory process rather than overexertion. Clear skin with no signs of stress suggests that the individual is not showing signs of physical distress, which does not point to overexertion. Lastly, no reported symptoms of fatigue implies that Stan is managing his energy levels well and does not display the common consequences of overexertion. Therefore, the assessment finding of rapid and shallow respirations is the most indicative of Stan's potential overexertion during physical therapy.
