Answer to Question 1

Correct Answer: 1
Approximately 35 of patients develop hypersensitivity to mafenide acetate, which can manifest as facial edema. Facial and neck edema is considered an adverse reaction. The information presented is inadequate to assess whether the dosage should be increased.

Answer to Question 2

Correct Answer: 1
Potassium levels are initially elevated at the onset of burn shock but decrease after burn shock resolves as fluid shifts back to intracellular and intravascular compartments. Reduced potassium levels are not indicators of the onset of renal or liver failure.
