Hint: 2 choices increase of cardiac output respiratory alkalosis excitement of sympathetic system stimulated pacemaker cells by increased temperature 5/12 endogenous pyrogen comes from? Hint: 3 choices monocytes blood platelet lymphocytes macrophages 6/12 in fever the more easy lack vitamins are? Hint: 2 choices vit A vit B vit C vit D 7/12 which factors do belong to the endogenous pyrogen? Hint: 2 choices endotoxin interlukin-1 tumor necrosis factor antigen antibody complex 8/12 In hyperthermia? Hint: 2 choices heat production may be increase heat loss may be decrease the set point of POAH is elevated the set point of POAH is not change 9/12 in the fevescence period of a fever? Hint: 3 choices body temperature > the set point of POAH heat production increases body temperature < the set point of POAH heat production > heat loss 10/12 fever easy induces the heart dysfunction because fever makes? Hint: 3 choices increasing heart load increasing myocardial perfusion some febrile activators inhibits myocardial function myocardium injure by some pyrogen cytokines 11/12 in the persistent febrile period of fever? Hint: 2 choices heat production increases heat loss increases heat production decreases heat loss decreases 12/12 which kinds acid base disturbance do been easy caused in fever? Hint: 2 choices metabolic acidosis respiratory acidosis respiratory alkalosis metabolic alkalosis
