IBAM 3-68-10 Module 3 Questions and Answers
5 Factors Affecting Exposure - (1) Physical condition - Answer: Poor __________ or illness will
prevent tolerance temperature extremes.
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.
5 Factors Affecting Exposure - (3) Nutrition & (4) Hydration - Answer: a decrease in either will
aggravate hot or cold stress.
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.
Habits that can affect regulation of temperature - Answer: (a) alcohol
(b) smoking
(c) use of sedatives, tranquilizers, anti-depressants, cardiovascular drugs (major factors for
hypothermia in seniors)
(d) sedentary lifestyle (deskbound) spending too much time seated, little exercise
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.
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.
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.
, IBAM 3-68-10 Module 3 Questions and Answers
Five ways body can loss heat - (3) Evaporation - Answer: Conversion of any liquid to a gas,
sweating and a natural cooling effect.
Five ways body can loss heat - (4) Radiation - Answer: Heat also may be lost by _______ to the
environment, primarily from non-insulated body areas.
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.
Heat loss or gain in the body can be modified in many ways - Answer: (a) Increase or decrease in
heat production.
(b) Shivering or increase in movement if cold
(c) Decrease and limit movement when hot
(d) Move to an area where heat loss can be decreased or increased
(e) Seek shelter from the wind in cold environments
(f) Covering the head can minimize heat loss by 70%
(g) Seek shade in a hot environment to cool a patient down
(h) Wear insulated clothing, which helps decrease heat loss in multiple ways
(i) Layers of clothing that trap air provide good insulation
(j) Also traps perspiration and prevents evaporation
(k) Loosen or remove clothing to cool down
Hypothermia /Physiology - Answer: (a) To protect against heat loss, the body constricts blood
vessels in the skin, resulting in blue lips and/or fingertips
(b) Secondarily, the body shivers to generate heat
(c) As these mechanisms are overwhelmed, body functions begin to slow down
