Nokea
Which zone consists of the area where the injury is most severe and deepest?
- A. Coagulation
- B. Stasis
- C. Hyperemia
- D. Necrosis
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.

A client is brought to the ED with burns exceeding 20% of total body surface area. Which is the primary nursing intervention in the care of this client?
- A. Prevent infection
- B. Fluid resuscitation
- C. Endotracheal tube placement
- D. Strict intake and output
Correct Answer: B
Rationale: Fluid resuscitation requirements are paramount in the management of clients having burns that exceed 20% of TBSA. Fluid resuscitation with crystaloid and colloid solutions is calculated from the time the burn injury occurred to restore the intravascular volume and prevent hypovolemic shock and renal failure. Infection prevention is a care consideration with all burns. Endotracheal tube placement may be necessary if respiratory factors indicate the need. Intake and output records are maintained to determine the success of fluid resuscitation efforts.
The nurse is teaching a client who underwent a skin graft for a burn injury about the use of pressure garments. What instruction(s) should the nurse include in the teaching? Select all that apply.
- A. Wear the garment at least 12 hours each day.
- B. Contact the primary provider if the garment does not seem to fit properly.
- C. Machine wash the pressure garment daily with a mild detergent.
- D. Roll the garment and wring tightly to ensure garment is as dry as possible after washing.
- E. Massage any moisturizers, lotions, creams, and petroleum-based ointments completely into the skin before donning the garment.
Correct Answer: B,E
Rationale: When using a pressure garment, the nurse should instruct the client to wear the garment for at least 23 hours a day, not 12 hours a day. The client should contact the primary provider if the garment does not seem to fit. The nurse should instruct the client to hand wash, not machine wash, the pressure garment daily with a mild detergent. The garment should not be wring dry. Instead, the client should squeeze and roll the garment in a towel to remove as much moisture as possible. The client should also massage any moisturizers, lotions, creams, and petroleum-based ointments completely into the skin before donning the garment.
A client brought to the emergency department has been exposed to smoke and flames from a house fire. What assessment finding is most important to the nurse in determining care of the client?
- A. Presence of soot around nasal passages
- B. Fracture of the fibula with displacement
- C. Elevation of blood pressure and heart rate
- D. Partial-thickness burns to hands and wrists
Correct Answer: A
Rationale: If the client has soot or evidence of carbon about the nasal passages, the nurse should anticipate respiratory difficulties. Edema and swelling of the internal airways may not be present initially but can progress quickly. Elevation of heart rate without hypotension is not as significant. Fracture to any bone as well as care of burns should be managed once the airway, breathing, and circulation are assessed and managed.
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?
- A. Anemia
- B. Gastric ulcers
- C. Hyperthyroidism
- D. Cardiac arrest
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.
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.
- A. Provides a drier environment
- B. Promotes heat loss
- C. Creates microbial barrier
- D. Prevents exudate accumulation
- E. Reduces pain during position changes
- F. Promotes slower healing
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.
