The nurse is reviewing laboratory values for a patient receiving treatment during the emergent phase of burn management. Which laboratory result should the nurse expect for the patient at this time:
Increased hematocrit
Decreased blood urea nitrogen (BUN)
Decreased serum potassium
increased serum albumin
The Correct Answer is A
Choice A rationale: During the emergent phase of burn management, patients commonly experience hemoconcentration due to fluid shift from the intravascular space to the interstitial space. This leads to an increase in hematocrit, indicating a higher concentration of red blood cells in the blood.
Choice B rationale: Burn injuries often result in increased protein breakdown and an elevation in BUN levels.
Choice C rationale: Burn injuries can cause the release of potassium from damaged cells, leading to hyperkalemia rather than hypokalemia.
Choice D rationale: The emergent phase of burn management is characterized by a decrease in serum albumin due to protein loss from the burned tissue and increased capillary permeability.

Correct Answer is D
Explanation
Choice A rationale: This describes a full-thickness burn with eschar formation, not a deep partial-thickness burn.
Choice B rationale: This may indicate a deeper burn involving the subcutaneous tissue, but the absence of blisters makes it less characteristic of a deep partial-thickness burn.
Choice C rationale: This suggests a full-thickness burn with damage to nerve endings, not a deep partial-thickness burn.
Choice D rationale: A deep partial-thickness burn is characterized by a pink or mottled appearance with the presence of blisters. This type of burn involves damage to the epidermis and portions of the dermis, causing pain and sensitivity to touch.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale: partial-thickness burns are usually characterized by the formation of blisters as a result of increased capillary permeability resulting in edema formation separating the epidermis from the dermis.
Choice B rationale: wound blanching with pressure is expected in partial-thickness burns due to compromised blood circulation.
Choice C rationale: This is not a typical finding in a partial-thickness burn.
Choice D rationale: this is incorrect since partial-thickness burns involve damage to the epidermis.
Choice E rationale: nerve endings are damaged in partial-thickness burns thus making the area sensitive to touch.
