How long does the stress phase usually last?

• A. 12 hours
• B. 24 hours
• C. 48 hours
• D. 72 hours

Answer: (B)

The main idea here is that the body’s acute response to severe stress—from injury, surgery, or critical illness—has a brief initial phase that lasts about one day. In this early period, there’s a surge of stress hormones and inflammatory mediators that drives a rapid rise in energy expenditure and protein breakdown to support vital organs. This hypermetabolic, catabolic state is most prominent for roughly 24 hours, after which the body often shifts into a different, more prolonged phase of metabolic stress. So, the best answer reflects this typical one-day duration for the initial stress response.
