pathophysiology practice test (3) <<<<<<<<<<<<<<<< Fever >>>>>>>>>>>>>>>> .............single choice........ shema published on May 18, 2012 Stacked 1/12 in the prsisten febrile period of fever? heat production increases and heat loss decreases heat production increases and heat loss increases heat production > heat loss heat production decreases and heat loss increases 2/12 how much does the heart rate increases when body temperature rises 1°C ? 5 to 10 beats/min 20 to 30 beats/min 10 to 20 beats/min 5 to 15 beats/min 3/12 in fever the effect of a endogenous pyrogen is? activating macrophage and monocytes exciting warm sensitive neurons of POAH elevating the set point of POAH inducing synthesis of the central febrile mediators 4/12 in fever the effect of a febrile activator is? activating macrophage and monocytes inducing release of the endogenous cryogen elevating the set point of POAH inducing release of the exogenous pyrogen 5/12 fever is? imbalance of heart production and heart loss heat production > the set point of POAH the set point is adjusted upwards heat production is increased heat loss decreased 6/12 in the fervescence period of fever? heat production increases and heat loss decreases heat prodution increases and heat loss increases heat production decreases and heat loss increases heat production decreases and heat loss decreases 7/12 which kind of water disturbance does been easy caused in fever? hypotonic dehydration water intoxication edema hypertonic dehydration 8/12 which kind acid-base disturbance does been easy caused in the fever? metabolic acidosis respiratory alkalosis respiratory acidosis metabolic alkalosis 9/12 where does the body consumption energy in fever major come from? glycogen catabolism fat catabolism protein catabolism carbohydrate 10/12 in the defervescence period of fever? heat production increases and heat loss decreases heat prodcution increases and heat loss increases heat production decreases and heat loss increases heat prodcution decreases and heat loss decreases 11/12 what is the effect of interlukin-1 in fever? a febrile activator a central febrile mediator an endogenous pyrogen elevating the set point of POAH 12/12 in fever the effect of endotoxin is? a febrile activator a central febrile mediator an endogenous pyrogen an exogenous pyrogen
