Question 1

The time between the end of burn shock and closure of the burn to less than 20% of total body surface area is called the _____ phase.&#10;A) postshock&#10;B) rehabilitation&#10;C) critical&#10;D) emergent

Accepted Answer

The time between the end of burn shock and closure of the burn to less than 20% of total body surface area is called the emergent phase.Postshock is not a phase of burn wound healing.The rehabilitation phase begins when the burn size is reduced to less than 20% TBSA and the patient is able to assume self-care.There is not a critical phase of burn wound healing.

Question 2

Nutritional support of the burned individual is designed to&#10;A) limit the glucose available to infectious organisms.&#10;B) create a positive nitrogen balance.&#10;C) protect the kidney from excessive protein intake.&#10;D) avoid hyperlipidemia.

Accepted Answer

Nutritional support for a burned individual focuses on creating a positive nitrogen balance, which means providing enough protein to meet the body's needs for repair and regeneration. Adequate protein intake also helps protect lean muscle mass, which can be lost due to the hypermetabolic state that often accompanies burns. Limiting glucose availability and avoiding hyperlipidemia may also be goals of nutritional support, but they are not as directly related to meeting the burned individual's nutritional needs. Protecting the kidney from excessive protein intake may be a concern in individuals with pre-existing kidney disease, but for most burned patients, protein is a crucial nutrient that should not be restricted excessively.

Question 3

The treatment of choice for major burn injury is&#10;A) excision of the burn followed by skin grafting.&#10;B) frequent wound debridement to encourage wound healing.&#10;C) hyperbaric oxygen therapy.&#10;D) continuous topical antibiotic therapy.

Accepted Answer

Excision of the burn followed by skin grafting is the most effective treatment for major burn injury as it can remove necrotic tissue and promote wound healing. Frequent wound debridement can lead to pain and may not always promote healing. Hyperbaric oxygen therapy is not typically used for burn injuries. Continuous topical antibiotic therapy may increase the risk of infection and does not address the underlying tissue damage.

Question 4

The first priority in rescuing a burned individual is&#10;A) establishing a patent airway.&#10;B) removing his or her clothing.&#10;C) eliminating the source of the burn.&#10;D) covering the wounds.

Accepted Answer

The answer of The first priority in rescuing a burned...

Question 5

The primary aim of burn wound management is to&#10;A) prevent trauma to burned tissue.&#10;B) prevent microbial colonization of the wound.&#10;C) keep the wound dry.&#10;D) prevent premature wound closure.

Accepted Answer

Preventing microbial colonization of the wound is crucial in burn wound management to prevent infections, which can worsen the healing process and lead to complications. The other options are also important considerations in burn wound management but are not the primary aim.

Question 6

Most of the manifestations of burn shock can be attributed to&#10;A) hypovolemia.&#10;B) cardiac depression.&#10;C) infection.&#10;D) increased capillary permeability.

Accepted Answer

Increased capillary permeability is a major factor in burn shock as it causes loss of fluid from the blood vessels into the tissues, leading to edema, hypovolemia, and decreased cardiac output. This can result in organ and tissue damage, and ultimately, shock. While hypovolemia and cardiac depression also play a role in burn shock, they are secondary to the increased capillary permeability. Infection may occur as a complication of burn injuries, but it is not a primary manifestation of burn shock.

Question 7

Burns covering 25% to 35% of the total body surface area&#10;A) are often associated with burn shock.&#10;B) can rarely be grafted.&#10;C) are nearly always fatal.&#10;D) are classified as major burns in children but not in adults.

Accepted Answer

The answer of Burns covering 25% to 35% of the...

Question 8

The most common cause of burn injuries in children is&#10;A) house fires.&#10;B) cigarette burns.&#10;C) scalding with hot water.&#10;D) contact with chemical agents.

Accepted Answer

Scalding with hot water is the most common cause of burn injuries in children, accounting for approximately 65% of all childhood burn injuries. House fires, cigarette burns, and contact with chemical agents are also common causes of burn injuries in children, but not as prevalent as scalding.

Question 9

Electrical shock may cause extensive damage to low-resistance tissues, particularly&#10;A) bone and muscle.&#10;B) nerves and blood vessels.&#10;C) epidermis.&#10;D) dermis and subcutaneous tissue.

Accepted Answer

Low-resistance tissues have high electrical conductivity and are more susceptible to damage from electrical shock. Nerves and blood vessels are examples of low-resistance tissues that can be extensively damaged by electrical shock.

Question 10

Second-degree, superficial partial-thickness burns&#10;A) are less painful than third-degree burns.&#10;B) involve only the epidermis.&#10;C) usually heal in 3 to 4 weeks.&#10;D) are rarely associated with scar formation.

Accepted Answer

The answer of Second-degree, superficial partial-thickness burns&#10;A) are less painful...
