Q1
5 Factors Affecting Exposure - (1) Physical condition
Answer: Poor or illness will prevent tolerance temperature extremes.
Q2
5 Factors Affecting Exposure - (2) Age
Answer: People in extremes of (too young or too old) will not be able to tolerate
temperature changes well. Infants cannot shiver.
Q3
5 Factors Affecting Exposure - (3) Nutrition & (4) Hydration
Answer: a decrease in either will aggravate hot or cold stress.
Q4
5 Factors Affecting Exposure - (5) Environmental conditions
Answer: weather will have a large impact on your patient's condition. Evaluate the
scene for clues to help with treatment in temperature extremes.
Q5
Habits that can affect regulation of temperature
Answer: alcohol smoking use of sedatives, tranquilizers, anti-depressants,
cardiovascular drugs (major factors for hypothermia in seniors) sedentary lifestyle
(deskbound) spending too much time seated, little exercise
Q6
Hypothermia
Answer: A core temperature of <35C (<95F). May even develop indoors during
summer. In the U.S. an average of 700 people dies of that, each year. Hall of those
who die of that are >65 years of age.
, Q7
Five ways body can loss heat - (1) Conduction
Answer: is the transfer of heat by direct contact down a temperature gradient, such as
from a warm body to the cold environment.
Q8
Five ways body can loss heat - (2) Convection
Answer: is the transfer of heat by the actual movement of heated material, such as
the wind's disrupting the layer of warm air surrounding the body.
Q9
Five ways body can loss heat - (3) Evaporation
Answer: Conversion of any liquid to a gas, sweating and a natural cooling effect.
Q10
Five ways body can loss heat - (4) Radiation
Answer: Heat also may be lost by to the environment, primarily from non-insulated
body areas.
Q11
Five ways body can loss heat - (5) Respiration
Answer: Evaporation of the water contained in exhaled, water-saturated air occurs
over a wide range of ambient temperatures and may be prevented by inhalation of
warmed, humidified air.
Q12
Heat loss or gain in the body can be modified in many ways
Answer: Increase or decrease in heat production. Shivering or increase in movement if
cold Decrease and limit movement when hot Move to an area where heat loss can be
decreased or increased Seek shelter from the wind in cold environments Covering the
head can minimize heat loss by 70% Seek shade in a hot environment to cool a patient
down Wear insulated clothing, which helps decrease heat loss in multiple ways Layers
of clothing that trap air provide good insulation Also traps perspiration and prevents
evaporation Loosen or remove clothing to cool down
