Which component is not part of the ebb response?

• A. Depressed energy expenditure
• B. Hyperglycemia
• C. Low plasma insulin
• D. Increased oxygen consumption

Answer: (D)

The ebb phase of the post-injury metabolic response is a brief, early period of reduced metabolism and energy use. During this phase, the body lowers its energy expenditure and overall metabolic rate, and oxygen consumption tends to be diminished as tissues receive less perfusion and activity slows. In contrast, the later flow (hypermetabolic) phase ramps up metabolism, with higher energy expenditure and an increased need for oxygen. The option describing increased oxygen consumption does not fit the ebb response because that uptick is characteristic of the flow phase, not the initial ebb. Hyperglycemia, while it can occur later with insulin resistance and stress hormones, and low plasma insulin can align with the ebb state, whereas a depressed energy expenditure is exactly what defines ebb.
