ATI(BURNS) PRACTICE EXAM QUESTIONS CORRECTLY SOLVED AND VERIFIED.
Thermal burns - CORRECT ANSWER occur when there is exposure to flames, steam, or hot liquids. This type of burn occurs most frequently, especially in older adults and children.
Chemical burns - CORRECT ANSWER s occur when there is exposure to a caustic agent. Cleaning agents used in the home (drain cleaner, bleach) and agents used in the industrial setting (caustic soda, sulfuric acid) cause chemical burns.
Electrical burns - CORRECT ANSWER occur when an electrical current passes through the body and can result in severe damage, including loss of organ function, tissue destruction with subsequent need for amputation of a limb, and cardiac and/or respiratory arrest
Radiation burns - CORRECT ANSWER most frequently occur as a result of therapeutic treatment for cancer or from sunburn
In addition to destruction of body tissue, a burn injury results in the loss of: - CORRECT ANSWER ◯ Temperature regulation
◯ Sweat and sebaceous gland function
◯ Sensory function
● Metabolism increases to maintain body heat as a result of burn injury and tissue damage
The severity of the burn is based on: - CORRECT ANSWER Percentage of total body surface area
Depth of the burn Body location of the burn
Emergent (resuscitative phase) - CORRECT ANSWER ■ First 24 to 48 hr after the burn occurs
Acute phase - CORRECT ANSWER ■ Begins when fluid resuscitation is finished
■ Ends when the wound is covered by tissue
Rehabilitative phase - CORRECT ANSWER Begins when most of the burn area is healed
■ Ends when reconstructive and corrective procedures are complete (may last for years)
Risk for Death from Burns - CORRECT ANSWER ■ Age greater than 60 years
■ Burn involves greater than 40% TBSA
■ Inhalation injury
◯ Older adults are at higher risk for damage to subcutaneous tissue, muscle, connective tissue, and bone because their skin is thinner.
◯ Older adults have a higher risk for complications from burns because of chronic illnesses (e.g., diabetes mellitus, cardiovascular disease).
Laboratory Tests - CORRECT ANSWER CBC, serum electrolytes, BUN, ABGs, fasting blood glucose, liver enzymes, urinalysis, and clotting studies.
☐ Initial fluid shift (first 24 hr after injury)
X Hct and Hgb - elevated due to loss of fluid volume and fluid shifts into interstitial space (third spacing)
X Sodium - decreased due to third spacing (hyponatremia)
X Potassium - increased due to cell destruction (hyperkalemia)
Fluid mobilization (48 to 72 hr after injury) - CORRECT ANSWER Hgb and Hct - decreased due to fluid shift from interstitial space back into vascular fluid
