Which statement best describes the washout phase of shock?

The washout phase describes the movement of accumulated acidic products from ischemic tissues into the bloodstream, leading to systemic acidosis. When tissues become poorly perfused, cells shift to anaerobic metabolism and generate lactic acid locally. If shock persists, these acids are released into the circulation, lowering the body's pH more broadly. This makes systemic acidosis the best description of the washout phase. Localized tissue acidosis happens early at the tissue level, not the body-wide washout. Edema reflects capillary leak and fluid shift, not the acid-base shift from tissue-to-blood, and reduced capillary blood flow is a consequence of shock rather than the specific washout process.
