Thermoregulation

Chapter 6 Thermoregulation




1. Conduction is:


A. heat transfer via air currents.

B. heat transfer via direct contact.

C. heat loss by conversion of liquid into vapor.

D. transfer of radiant energy without direct contact through absorption and emission of infrared rays.

2. Convection is:


A. heat transfer via air currents.

B. heat transfer via direct contact.

C. heat loss by conversion of liquid into vapor.

D. transfer of radiant energy without direct contact through absorption and emission of infrared rays.

3. Evaporation is:


A. heat transfer via air currents.

B. heat transfer via direct contact.

C. heat loss by conversion of liquid into vapor.

D. transfer of radiant energy without direct contact through absorption and emission of infrared rays.

4. Radiation is:


A. heat transfer via air currents.

B. heat transfer via direct contact.

C. heat loss by conversion of liquid into vapor.

D. transfer of radiant energy without direct contact through absorption and emission of infrared rays.

5. Thermoregulation is:


A. a balance of heat loss, heat gain, and heat production.

B. a state in which the temperature of the body is out of the expected normal range.

C. the inability to maintain core temperature above that of the environment.

D. a physiologic response to changes in ambient temperature in an attempt to maintain normal core temperature.

6. Thermal instability is:


A. a balance of heat loss, heat gain, and heat production.

B. a state in which the temperature of the body is out of the expected normal range.

C. the inability to maintain core temperature above that of the environment.

D. a physiologic response to changes in ambient temperature in an attempt to maintain normal core temperature.

7. Infants are at risk of hyperthermia because infants have:


A. a large body surface area.

B. limited glycogen stores.

C. limited brown fat stores.

D. limited ability to dissipate heat.

8. Maintaining a neutral thermal environment is important because it:


A. limits the neonate in maintaining normothermia.

B. promotes minimal consumption of oxygen and glucose.

C. increases the neonate’s metabolic rate.

D. enables the neonate to maximize glucose consumption.

9. Which of the following puts an infant at risk for experiencing hypothermia?


A. Increased muscle tone
