A nurse is caring for a client who has been hospitalized for treatment of bipolar disorder and will be discharged with a prescription for lithium. The nurse's discharge teaching should include information cautioning against which of the following factors that may cause lithium toxicity?

A. Experiencing diarrhea Rationale: Lithium is used to treat the manic stage of bipolar disorder. Toxicity occurs when the level of lithium in the blood becomes too high. A low sodium level, or factors which result in a low sodium level, (such as dehydration, diarrhea, sweating, excess exercise in hot weather, diuretic use, a low sodium diet) increases the lithium level because the kidney processes sodium and lithium in the same way.
