The response to shock includes which of the following metabolic effects?
The biochemical changes associated with shock result from tissue hypoperfusion, endocrine response to stress, and specific organ system failure. During shock, the sympathetic nervous system and adrenal medulla are stimulated to release catecholamines. Renin, angiotensin, antidiuretic hormone, adrenocorticotropin, and cortisol levels increase. Resultant changes include sodium and water retention and an increase in potassium excretion, protein catabolism, and gluconeogenesis. Potassium levels rise as a result of increased tissue release, anaerobic metabolism, and decreased renal perfusion. If renal function is maintained, potassium excretion is high and normal plasma potassium levels are restored.
Increase in sodium and water excretion
Increase in renal perfusion
Decrease in cortisol levels
Hyperkalemia
Trauma
