Chapter 62 : Managements of Patients with Burn Injury Questions
Question 1 of 5
A patient in the emergent/resuscitative phase of a burn injury has had blood work and arterial blood gases drawn. Upon analysis of the patients laboratory studies, the nurse will expect the results to indicate what?
Correct Answer: A
Rationale: In the emergent phase, cell damage releases potassium (hyperkalemia), sodium is lost to edema (hyponatremia), hemoconcentration increases hematocrit, and tissue hypoxia causes metabolic acidosis. Other combinations do not align with burn pathophysiology.
Question 2 of 5
A patient has experienced an electrical burn and has developed thick eschar over the burn site. Which of the following topical antibacterial agents will the nurse expect the physician to order for the wound?
Correct Answer: B
Rationale: Mafenide acetate penetrates thick eschar, making it ideal for electrical burns with deep tissue involvement. Silver sulfadiazine and silver nitrate do not penetrate eschar effectively, and Acticoat is a dressing, not a topical agent.
Question 3 of 5
An occupational health nurse is called to the floor of a factory where a worker has sustained a flash burn to the right arm. The nurse arrives and the flames have been extinguished. The next step is to cool the burn. How should the nurse cool the burn?
Correct Answer: D
Rationale: Cool towels or water applied intermittently relieve pain and limit tissue damage without causing hypothermia, which ice can induce. Oil-based substances like butter trap heat, worsening the burn.
Question 4 of 5
An emergency department nurse has just admitted a patient with a burn. What characteristic of the burn will primarily determine whether the patient experiences a systemic response to this injury?
Correct Answer: D
Rationale: TBSA is the primary determinant of systemic response, as larger burns cause greater fluid loss, metabolic demand, and organ stress. Time, location, and source are secondary factors.
Question 5 of 5
A nurse on a burn unit is caring for a patient in the acute phase of burn care. While performing an assessment during this phase of burn care, the nurse recognizes that airway obstruction related to upper airway edema may occur up to how long after the burn injury?
Correct Answer: A
Rationale: Upper airway edema from burns can develop up to 48 hours post-injury due to inflammation and fluid shifts, requiring vigilant monitoring. Later onset is less likely.
