A healthcare provider is reviewing laboratory values for a group of patients. It is essential for the nurse to identify laboratory results that indicate potential risks for the patients. The following laboratory values are presented:

For Patient A, the potassium level is 6.1 mEq/L. For Patient B, the sodium level is 120 mEq/L. For Patient C, the glucose level is 50 mg/dL. For Patient D, the hemoglobin A1c is 8.5%. For Patient E, the creatinine level is 3.2 mg/dL. For Patient F, the calcium level is 8.0 mg/dL.

Select all the laboratory values that indicate potential risk to the patients.
