Choice A rationale:
Taking lithium on an empty stomach is not necessary. Lithium can be taken with or without food.
Choice B rationale:
Excessive salivation is not a common side effect of lithium.
Choice C rationale:
Vomiting or diarrhea can lead to dehydration, which increases the risk of lithium toxicity by reducing the excretion of lithium. Therefore, it’s important to notify your provider if you experience these symptoms.
