Of the following mechanisms of heat loss by the body, identify the mechanism that transfers heat away by using air movement?
 
  a. Radiation
  b. Conduction
  c. Convection
  d. Evaporation

Question 2

The patient has a temperature of 105.2 F. The nurse is attempting to lower his temperature by providing tepid sponge baths and placing cool compresses in strategic body locations.
 
  The nurse is attempting to lower the patient's temperature through the use of
  a. Radiation.
  b. Conduction.
  c. Convection.
  d. Evaporation.

Answer to Question 1

ANS: C
Convection is the transfer of heat away from the body by air movement. Conduction is the transfer of heat from one object to another with direct contact. Radiation is the transfer of heat from the surface of one object to the surface of another without direct contact between the two. Evaporation is the transfer of heat energy when a liquid is changed to a gas.

Answer to Question 2

ANS: B
Applying an ice pack or bathing a patient with a cool cloth increases conductive heat loss. Radiation is the transfer of heat from the surface of one object to the surface of another without direct contact between the two. Evaporation is the transfer of heat energy when a liquid is changed to a gas. Convection is the transfer of heat away from the body by air movement.
