A nurse is assisting with the care of a client in an emergency department (ED). Which of the following laboratory findings should the nurse report to the provider? Select all that apply.

A. Potassium: The client’s potassium level is 4.1 mEq/L, which is within the normal range of 3.5–5 mEq/L. No immediate intervention is required, so this value does not need to be reported. B. Hematocrit: The client’s hematocrit is 44%, which falls within the normal reference range of 37–47% for adults. This level is not clinically concerning and does not require reporting. C. Sodium: The client’s sodium level is 140 mEq/L, which is within the normal range of 136–145 mEq/L. This electrolyte level is stable and does not require provider notification. D. AST: The client’s AST is 42 U/L, slightly above the reference range of 0–35 U/L. Elevated AST may indicate hepatocellular injury or inflammation, possibly related to gallbladder disease or liver involvement, and should be reported for further evaluation. E. WBC count: The client’s WBC count is 15,100/mm³, which is above the normal range of 5,000–10,000/mm³. Leukocytosis can indicate infection or inflammation, consistent with the client’s abdominal pain and possible biliary or gastrointestinal pathology, and requires provider notification.
