5. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Question 05/25 Pg 1053 Is the following statement true or false? A burn’s severity is affected by the temperature of the heat source.

6. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer 06/25 Pg 1053 True. A burn’s severity is affected by the temperature of the heat source. Additional factors, which affect a burn’s severity include duration of contact, thickness of tissue exposed to the heat, and the location of the burn.

10. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Question 10/25 Pg 1053 Is the following statement true or false? Burns can affect fluid balance.

11. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer 11/25 Pg 1053 True. As a response to the trauma of a burn, fluid shifts, which results in edema. Not only does it result in edema, the fluid is trapped and unavailable to the rest of the body. Decreased blood pressure (due to decreased fluid volume) can result in irreversible shock.

15. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Question 15/25 Pg 1056 Is the following statement true or false? An infection within a burn wound can be life- threatening.

16. Copyright © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer 16/25 Pg 1056 True. An infection within a burn wound can be life- threatening. Outcome of a burn injury depends on the initial first aid and subsequent acute treatment. Three complications of burns can be life-threatening: inhalation injury, hypovolemic shock, and infection.
