What are the factors that affect heat production?

1. Basal metabolic rate
2. Muscle activity
3. Thyroxine output
4. Epinephrine, norepinephrine, and sympathetic stimulation/stress response
5. Fever

1

True/False

Generally the younger the person, the higher the BMR (basal metabolic rate).

True

2

What ways is heat lost from the body?

- Radiation
- Conduction
- Convection
- Evaporation

3

Insensible heat loss accounts for about ______ of basal heat loss.

10%

4

The system that regulates body temperature has three main parts:

- Sensors in the periphery and in the core
- An integrator in the hypothalamus
- Effector system that adjusts the production and loss of heat

5

Factors that affect body temperature

1. Age
2. Diurnal variations (circadian rhythms)
3. Exercise
4. Hormones
5. Stress
6. Environment

6

Why are older people at risk for hypothermia?

- Inadequate diet
- Lack of activity
- Reduced thermoregulatory efficiency
(Also sensitive to extremes in environmental temp due to decreased thermoregulatory controls.)

8

The time for the point of highest body temperature is usually between ____ and _____ hours; the lowest point is between _____ and _____ hours.

1600 and 1800 hours (4 and 6 PM)

0400 and 0600 hours (4 and 6 AM)

9

True/False

Men usually experience more hormone fluctuations than women.

False

10

The normal range for body temperature in adults is considered to be between ____ and ____.

96.8F to 99.5F

11

There are two primary alterations in body temperature: ________ and _______.

Pyrexia and hypothermia

12

A body temperature above the usual range is called:

- Pyrexia
- Hyperthermia
- Fever

13

A very high fever, such as 105.8F, is called _______.

hyperpyrexia
