EMT - B Chapter 33 Quiz
High humidity reduces the body's ability to lose heat through:
evaporation
Geriatric patients, newborns, and infants are especially prone to hyperthermia because they:
exhibit poor thermoregulation.
Covering a patient's _________ will significantly minimize radiation heat loss.
head
Common signs and symptoms of heat exhaustion include all of the following, except:
hot, dry skin.
A frostbitten foot can be identified by the presence of:
mottling and blisters.
A 20-year-old male was pulled from cold water by his friends. The length of his submersion is not known and was not witnessed. You perform a primary assessment and determine that the patient is apneic and has a slow, weak pulse. You should:
provide rescue breathing, remove his wet clothing, immobilize his entire spine, keep him warm, and transport carefully.
High air temperature reduces the body's ability to lose heat by:
radiation.
A patient with a core body temperature of 95°F (35°C) will most likely experience:
rapid breathing.
Heatstroke occurs when:
the body's heat-eliminating mechanisms are overwhelmed.
An air embolism associated with diving occurs when:
the diver holds his or her breath during a rapid ascent.
Rough handling of a hypothermic patient with a pulse might cause:
ventricular fibrillation.
A person's ability to shiver is lost when his or her body temperature falls below:
90°F (32°C).
Hypothermia occurs when the core body temperature falls below:
95°F (35°C).
Compared to adults, infants and children are at higher risk for hypothermia for all of the following reasons, except:
a relatively small surface area.
Signs of late heatstroke include:
a weak, rapid pulse.
To assess a patient's general body temperature, pull back on your glove and place the back of your hand on his or her skin at the:
abdomen.
A dysbarism injury refers to the signs and symptoms related to changes in:
barometric pressure.
The diving reflex might allow a person to survive extended periods of submersion in cold water secondary to:
bradycardia and a slowing of the metabolic rate.
The venom of a brown recluse spider is cytotoxic, meaning that it:
causes severe local tissue damage.
The transfer of heat to circulating air, such as when cool air moves across the body's surface, is called:
convection.
