A nurse in a mental health facility is reviewing the laboratory results of a client who is taking lithium carbonate. Which of the following findings places the client at risk for lithium toxicity?

A: Aspartate aminotransferase within normal range, not directly related to lithium toxicity.
B: WBC within normal range, not directly related to lithium toxicity.
