Answer to Question 1
A
An elevated body temperature related to the body's inability to promote heat loss or reduce heat production is hyperthermia (hyper- means excessive; therm means heat). Prolonged exposure to the sun or high environmental temperatures overwhelms the body's heat loss mechanisms. Heat also depresses hypothalamic function. These conditions cause heat stroke, a dangerous heat emergency, defined as a body temperature of 40.2 C (104.4 F) or more. Heat loss during prolonged exposure to cold overwhelms the body's ability to produce heat, causing hypothermia. The term fever of unknown origin (FUO) refers to a fever whose cause cannot be determined.
Answer to Question 2
A

The scientific process, interpersonal relationships, and new technologies do not indicate ethical behavior like competent care.
