Question 1

Third-degree burns are minor and result only in a mild inflammation of the skin, known as erythema.

Accepted Answer

This statement is false. Third-degree burns are actually the most severe type of burns and extend through the entire skin layer, causing damage to the underlying tissues and nerves. This can result in significant pain, scarring, and even loss of function.

Question 2

Hypothermia is the condition that results when the body's core temperature drops to dangerously low levels.

Accepted Answer

This is correct. Hypothermia occurs when the body's core temperature drops below 95°F (35°C) and can lead to serious health complications if not treated promptly.

Question 3

Infection in a burn wound can cause septicemia.

Accepted Answer

Infection in a burn wound can easily spread to the bloodstream, causing septicemia or blood poisoning. It is important to keep burn wounds clean and properly treated to prevent infection and the risk of sepsis.

Question 4

The severity of a burn depends on several factors. The most important of these is:&#10;A) Age of victim&#10;B) Location of burn&#10;C) Amount of burned area&#10;D) Depth to which burn penetrates

Accepted Answer

The depth to which the burn penetrates is the most important factor in determining the severity of a burn. A superficial burn only affects the outer layer of skin, while a deep burn penetrates deeper layers, including muscle and bone, which can be life-threatening. While age, location, and amount of burned area are also important considerations, they are secondary to the depth of the burn.

Question 5

The skin serves several important purposes including the following: protection of body tissue, sensation, secretion, excretion, and respiration.

Accepted Answer

The skin is the body's largest organ and has several important functions, including protection from the external environment, sensation, secretion of sweat and oil, excretion of waste products, and vitamin D synthesis.

Question 6

Heat exhaustion is a type of heat stress that occurs as a result of water and/or salt depletion.

Accepted Answer

Heat exhaustion occurs when the body loses water and/or salt through excessive sweating, leading to dehydration and an imbalance in electrolytes.

Question 7

Damage from frostbite can affect only the outer layer of the skin.

Accepted Answer

Damage from frostbite can affect not only the outer layer of the skin, but also the deeper tissues such as muscles and bones. It can even lead to permanent damage or amputation.

Question 8

First-degree burns are classified as critical burns.

Accepted Answer

First-degree burns are considered minor burns and are not classified as critical.

Question 9

Critical burns are second-degree burns covering what percentage of BSA (Body Surface Area)?&#10;A) 10%&#10;B) 5%&#10;C) 15%&#10;D) 30%

Accepted Answer

Critical burns are second-degree burns that cover at least 30% of the body surface area. A second-degree burn is characterized by partial-thickness skin damage involving the dermis and epidermis. Burns covering less than 30% of the body surface area are considered moderate or minor.

Question 10

Windchill factor is the cooling effect produced by a combination of temperature, wind, velocity, and/or air movement.

Accepted Answer

The definition of windchill factor states that it is a combination of temperature, wind velocity, and/or air movement that produces a cooling effect.

Question 11

When heat gain from any source or sources is more than the body can compensate for by sweating, the result is:&#10;A) Internal heat gain&#10;B) Heat stress&#10;C) Body heat&#10;D) Convection heat gain

Accepted Answer

The answer of When heat gain from any source or...

Question 12

Radiant heat is the result of:&#10;A) Conduction&#10;B) Convection&#10;C) Electromagnetic nonionizing energy&#10;D) Acclimatization

Accepted Answer

The answer of Radiant heat is the result of:&#10;A) Conduction&#10;B)...

Question 13

Which of the following is a potential harmful effect of the chemical Methylbromide?&#10;A) Tissue damage&#10;B) Blisters&#10;C) Ulceration&#10;D) Eye burns

Accepted Answer

The answer of Which of the following is a potential...
