When determining the BSA involved in a burn, the EMT should remember that the palm of the patient's hand is equal to about what percentage of total body area?

1percent

In estimating the BSA affected by a burn, each upper extremity in an adult represents what percentage of the total body area?

9 percent

Burn injuries 10 minutes of injury need to be __ within approximately the first

Cooled down

Bums are classified according to the___ of injury

Depth

___ damage to soft tissues, but also internal iniuries to the body as a whole burns can cause not only severe

Electrical

A superficial bum is an injury that involves only the ___ layer of the skin

Epidermal

The three layers of the skin are the

Epidermis, dermis, subcutaneous

The tough and leathery dead soft tissue formed in a full-thickness burn injury is called

Eschar

All layers of the skin are damaged

Full thickness

One method that the EMT can use to estimate the body surface area damaged by a burn is the

Rule of 9

A partial-thickness bun is also called a(n) -degree burn

Second

Once the EMT has determined that the scene of a burn emergency is safe to enter, he should immediately take

Standard precautions

Examples of superficial bums include a minor

Sunburn

All of the following are important factors to consider in determining burn severity except

ambient environmental temperature

In managing a burn correctly, an EMT may take all of the following steps except

apply ointments or sprays

When dealing with chemical buns, the EMT should remember that dry chemicals should be

brushed away before irrigated

A burn that encircles a body area such as the chest, an arm, or a leg is called

circumferential

The most important treatrment for a patient who has sustained a chemical burn to the eyes is

copious irrigation with water

When administering emergency medical care to a burn patient, clothing that has adhered to a burned area should be

cut around and left in place

Buns are classified according to

depth of the injury

Absence of pain in a patient with a severe burn is most commonly associated with a

full-thickness bun

In a child younger than age 5, any partial-thickness burn involving between 10 and 20 percent of BSA should be considered

moderate

A burn in which the epidermis and dermis are damaged is known as a

partial-thickness burn

When the EMT is dealing with a patient who has experienced an electrical burn, the primary concern should be

personal safety

A partial-thickness (second-degree) burn will appear

reddened

The most serious problem usually associated with electrical shocks is

respiratory and/or cardiac arrest

The innermost layer of the skin is the

subcutaneous

An example of a superficial burn would be a(n)

sunbum

In cases of chemical bums to the eyes, the EMT should flood the eves with

water
