pathophysiology practice test (4) <<<<<<<<<<<<<<< Fever >>>>>>>>>>>>>>>> ............multiple choice........... shema published on April 27, 2012 Stacked 1/12 which factors do belong to the febrile activators? exotoxin pathogenic microorganism antigen antibody complexes endotoxin 2/12 which factors do belong to the endogenous pyrogen? Hint: 2 choices endotoxin interlukin-1 tumor necrosis factor antigen antibody complex 3/12 in the persistent febrile period of fever? Hint: 2 choices heat production increases heat loss increases heat production decreases heat loss decreases 4/12 which kinds acid base disturbance do been easy caused in fever? Hint: 2 choices metabolic acidosis respiratory acidosis respiratory alkalosis metabolic alkalosis 5/12 which factors do belong to the febrile activators? endotoxin interlukin-1 antigen antibody complex tumor necrosis factor 6/12 in the defervescence period of a fever? heat production decreases heat loss increases body temperature > the set point of POAH heat loss > heat production 7/12 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 8/12 endogenous pyrogen comes from? Hint: 3 choices monocytes blood platelet lymphocytes macrophages 9/12 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 10/12 in fever the mechanism of increased heart rate is by? Hint: 2 choices increase of cardiac output respiratory alkalosis excitement of sympathetic system stimulated pacemaker cells by increased temperature 11/12 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 12/12 in fever the more easy lack vitamins are? Hint: 2 choices vit A vit B vit C vit D
