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 ["31.5"]
Explanation
Rationale: the anterior chest wall and abdomen accounts for 18%, the left upper limb 9 % (4.5% anteriorly and 4.5% posteriorly), and the right upper limb 4.5% (2.25% anteriorly and 2.25% posteriorly).
(18+9+4.5) =31.5%
Correct Answer is B
Explanation
Choice A rationale: Circular, erythematous patches on the scalp are more indicative of tinea capitis, a fungal infection affecting the scalp, and not tinea pedis.
Choice B rationale: Tinea pedis, commonly known as athlete's foot, typically presents with symptoms such as scaling, redness, and itching between the toes. It is a fungal infection affecting the feet.
Choice C rationale: Poison ivy exposure would result in contact dermatitis, characterized by a rash and blistering, rather than the typical presentation of tinea pedis.
Choice D rationale: Antiseizure medications are not typically associated with the development of tinea pedis; the symptoms described are more consistent with a fungal infection.
