the epidermis and dermis at varying depths. Coagulation necrosis, damage to all skin
elements, and the destruction of nerve endings are observed in full-thickness burn
injuries.

A nurse working in a burn unit identifies that which patients are at an increased risk of
developing venous thromboembolism? Select all that apply.
1
Young age
2
Morbid obesity
3
Prolonged immobility
4
Upper-extremity burns
5
First-degree burn of a finger - (correct answer)2, 3
,The risk factors for the development of venous thromboembolism a burn patient are
morbid obesity and prolonged immobility. These patients may develop stasis of blood
due to immobility, which results in development of venous thromboembolism. Young age
is not a risk factor for venous thromboembolism; rather, old age predisposes a person to
venous thromboembolism. Usually lower-extremity burns are risk factors for venous
thromboembolism, because they cause stagnation of blood. First-degree burn of a
finger is not an extensive burn and hence not a risk factor for venous thromboembolism.

Which complication is caused by an electric burn?
1
Myoglobinuria
2
Systemic toxicity
3
Protein hydrolysis
4
Metabolic asphyxiation - (correct answer)1
Electric burns often cause the release of myoglobin from injured muscle tissues into
circulation, causing myoglobinuria. Systemic toxicity and protein hydrolysis results from
chemical injury. Smoke and inhalational injury results in metabolic asphyxiation.

A nurse is teaching a group of parents how to reduce the risk for injury related to burns.
Which statement by a participant indicates effective learning?
1
"Frayed wires are OK to use at home."
2
"I should hold regular home fire exit drills."
3
, "I should use gasoline with care to start a fire."
4
"I should perform outdoor activities with caution during electrical storms." - (correct
answer)2
Regular home fire exit drills ensure the family knows the primary escape routes in case
of any flame accidents at home. Frayed wires lack protective insulation, and contact
may result in electrical injuries. Gasoline or kerosene should never be used to start a
fire. Outdoor activities should be avoided during electrical storms.

assign what percentage to a burn in the genitalia?
1
1%
2
4.5%
3
9%
4
18% - (correct answer)1
The Rule of Nines is a formula used for calculating the percentage of burns during initial
assessment of a burn patient. The genitals are assigned 1%. Burns in the head and
arms are assigned 4.5% each. Burns on the lower extremities are assigned 9% each.
Burns in the chest and back are assigned 18%.
