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.
