While reviewing the chart of an elderly client, the nurse notes that the last recorded temperature for the preceding shift was 104°. There is no documented intervention. The nurse should:

- B. Ask the client whether he has received any medication for his fever.
- C. Call the nurse at home to validate whether the medication was given.
