Which of the following is a physiologic response to stress?

  1. Decreased blood glucose levels

  2. Flushed skin

  3. Increased muscle control

  4. Increased blood pressure

The correct answer is: Decreased blood glucose levels

A physiologic response to stress typically involves the body's fight-or-flight response, which is triggered by the release of stress hormones such as cortisol and adrenaline. During this response, the body releases stored glucose in order to provide a quick source of energy for the muscles. As a result, blood glucose levels increase to support the body's heightened state of arousal and preparedness for action. Therefore, decreased blood glucose levels (Option A) would not be a typical physiologic response to stress. Flushed skin (Option B) may occur due to increased peripheral blood flow but is not a consistent response to stress. Increased muscle control (Option C) is not typically seen as a direct response to stress. On the other hand, increased blood pressure (Option D) is a common physiologic response to stress as part of the body's preparation for heightened physical activity or response to a perceived threat.
