A nurse is caring for a patient who has suffered a major burn. Of the lab values listed, which would be concerning as it is a strong indicator of massive cell destruction?

A. Calcium 8.0 mg/dL: A calcium level of 8.0 mg/dL is slightly below the normal range but is not a strong indicator of massive cell destruction. It may be seen in a variety of conditions, including burns, but it is not as directly concerning as other findings. B. Glucose 180 mg/dL: Elevated glucose levels can occur due to stress, such as a burn injury, and are not specifically indicative of massive cell destruction. Stress-induced hyperglycemia is common and may resolve with proper management of the burn and stress response. C. Potassium 6.0 mg/dL: Potassium levels of 6.0 mg/dL or higher can be a strong indicator of massive cell destruction. In burn injuries, the breakdown of cells (especially muscle cells) releases intracellular potassium into the bloodstream, leading to hyperkalemia, which is life-threatening and requires immediate attention. D. Sodium 130 mEq/L: A sodium level of 130 mEq/L indicates mild hyponatremia. While electrolyte imbalances are common in burn patients, this is not as immediately concerning as hyperkalemia and is typically addressed through fluid management.
