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 A
Explanation
Choice A rationale:
Adherence to medication, especially after the resolution of acute psychosis, is crucial when taking an antipsychotic like clozapine. This is because discontinuation can lead to a relapse of symptoms.
Choice B rationale:
There’s no specific need to limit fluid intake when taking an antipsychotic.
Choice C rationale:
While routine blood cell count laboratory work is important, it’s not specific to red blood cells but rather to monitor for agranulocytosis, a potential side effect of clozapine.
Choice D rationale:
Avoiding foods that contain tyramine is typically associated with monoamine oxidase inhibitors, not antipsychotics like clozapine.

Lip smacking and tongue thrusting are not typically associated with lithium toxicity.
Choice C rationale:
