. . . .
Answer 1 is correct because burns increase cellular metabolism, resulting in an increased oxygen demand. Answer 2 is incorrect because the metabolic demand and need for oxygen decrease with hypothermia. Answer 3 is correct because shivering raises the metabolism and the demand for oxygen. Answer 4 is correct because the energy expended with agitation increases oxygen utilization. Answer 5 is incorrect because the metabolic demand is decreased, and therefore oxygen demand is decreased. Answer 6 is correct because hyperthyroidism increases cellular metabolism and increases oxygen demand.
