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?
Drinking green tea.
Exercising moderately.
Increasing sodium intake.
Experiencing diarrhea.
The Correct Answer is D
Choice A rationale:
Drinking green tea does not directly cause lithium toxicity.
Choice B rationale:
Moderate exercise does not directly cause lithium toxicity.
Choice C rationale:
Increasing sodium intake does not directly cause lithium toxicity. In fact, a sudden decrease in sodium intake can increase the risk of lithium toxicity.
Choice D rationale:
Experiencing diarrhea can lead to dehydration, which increases the risk of lithium toxicity by reducing the excretion of lithium.

Correct Answer is C
Explanation
Choice A rationale:
A lithium level of 1.8 mEq/L is above the therapeutic level for initial treatment (0.8 to 1.4 mEq/L)3.
Choice B rationale:
A lithium level of 1.8 mEq/L is above, not below, the therapeutic treatment level.
Choice C rationale:
A lithium level of 1.8 mEq/L is at the toxic level. A blood lithium level greater than 1.5 mEq/L indicates toxicity.
Choice D rationale:
A lithium level of 1.8 mEq/L is not within the maintenance treatment level (0.4 to 1.3 mEq/L)3.
Correct Answer is D
Explanation
Choice A rationale:
Diarrhea is not a specific reason to stop lithium. However, severe diarrhea can affect lithium levels and should be reported to a healthcare provider.
Choice B rationale:
Lithium does not need to be taken on an empty stomach. It can be taken with or without food.
Choice C rationale:
A low-salt diet is not recommended while on lithium. In fact, a consistent, normal sodium intake is important because low sodium levels can cause lithium levels to become too high.
Choice D rationale:
Regular blood tests are necessary when taking lithium to ensure therapeutic levels and prevent toxicity. Weekly blood tests may be required during the first month of treatment.
