MULTIPLE CHOICE
1. It is true that second-degree, superficial partial-thickness burns
a. are less painful than third-degree burns.
b. involve only the epidermis.
c. usually heal in 7 to 21 days.
d. are rarely associated with scar formation.
ANS: C
Second-degree, superficial partial-thickness burns usually heal in 7 to 21 days. Second-degree burns are more painful than
third-degree burns, involve damage to the dermis, and can be associated with scar formation.
REF: Pg. 1093
2. The first priority when rescuing a burned individual is
a. establishing a patent airway.
b. removing his or her clothing.
c. eliminating the source of the burn.
d. covering the wounds with wet sheets.
ANS: C
The first priority in rescuing a burned individual is eliminating the source of the burn. The next priority is to establish a patent
airway. Removing the clothing is not recommended; however, dry, clean sheets or dressings should be placed over the burns.
Covering the wound is not advised, as this may cause hypothermia.
REF: Pg. 1095
3. Burn shock is the direct result of
a. hypovolemia.
b. cardiac depression.
c. infection.
d. increased capillary permeability.
ANS: D
Burn shock results from systemic capillary permeability with leakage of fluids throughout all tissues; the result is massive edema.
Hypovolemia is not the direct cause of burn shock. Burn shock does not result from cardiac depression or infection.
REF: Pgs. 1096-1097
4. Electrical injury may cause extensive damage to low-resistance tissues, particularly
a. bone and muscle.
b. nerves and blood vessels.
c. epidermis.
d. dermis and subcutaneous tissue.
ANS: B
Electrical injury may cause extensive damage to low-resistance tissues, particularly nerves and blood vessels. Bone and muscle, and
dermis and subcutaneous tissue, are not low-resistance tissues. Skin is a high-resistance tissue.
REF: Pg. 1105
5. 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.
a. postshock
b. rehabilitation
c. critical
d. emergent
ANS: D
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.
