Chapter 66 : Caring for Clients With Burns Questions
Question 1 of 5
What is a benefit(s) that supports the use of a closed method wound care in the management of a client with burns? Select all that apply.
Correct Answer: C,E
Rationale: The closed method is the preferred method of wound management for most burn victims. It creates a microbial barrier and applies direct pressure to the wound, which reduces pain during position changes. Closed wound management provides a moist environment while reducing heat loss and evaporation, which facilitates faster healing. Frequent dressing changes may be required if the wound is infected or when there is significant exudate accumulation.
Question 2 of 5
Skin substitutes are often used after the wound is debrided and cleaned. What is the purpose(s) for the use of a skin substitute? Select all that apply.
Correct Answer: A,F
Rationale: Skin substitutes provide a temporary covering of the burn area and lessen the potential for infection. The covering decreases pain associated with contact and exposure to the air. The covering decreases fluid loss through evaporation and discourages granulation tissue, which contains fibroblasts causing scars. The skin substitute promotes tissue generation and healing.
Question 3 of 5
A client with a burn injury is in acute stress. The nurse knows that which of the following complications is prone to develop in this client?
Correct Answer: B
Rationale: The release of histamine as a consequence of the stress response increases gastric acidity. The client with a burn is prone to develop gastric ulcers. Anemia develops because of the heat destroying the erythrocytes. Release of histamine does not cause hyperthyroidism or cardiac arrest.
Question 4 of 5
Which zone consists of the area where the injury is most severe and deepest?
Correct Answer: A
Rationale: The zone of coagulation is at the center of the injury and is the area of injury that is most severe and the deepest. The zone of stasis is the area of intermediate burn injury. The zone of hyperemia is the area of least injury. Where the epidermis and dermis are only minimally damaged. There is no zone of necrosis.
Question 5 of 5
Which type of debridement occurs when nonliving tissue slough away from uninjured tissues?
Correct Answer: B
Rationale: Natural debridement is accomplished when nonliving tissue slough away from uninjured tissue. Mechanical debridement involves the use of surgical tools to separate and remove the eschar. Enzymatic debridement encompasses the use of topical enzymes to the burn wound. Surgical debridement uses the use of forceps and scissors during dressing changes or wound cleaning.
