After teaching a client about lithium carbonate (Eskalith), a nurse would consider the teaching successful on the basis of which client statement?

Choice A reason: Diarrhea and tinnitus are early signs of lithium toxicity. Recognizing and reporting these symptoms demonstrates understanding of critical safety information. This response reflects accurate knowledge of when to seek medical attention. Choice B reason: Lithium takes 1–3 weeks to reach therapeutic levels. Expecting rapid improvement indicates a misunderstanding of the drug’s pharmacokinetics. Choice C reason: Doubling a missed dose is dangerous and can lead to toxicity. This statement reflects poor medication safety knowledge. Choice D reason: Sodium intake affects lithium levels, but stopping salt entirely can destabilize lithium levels. The goal is consistent sodium intake, not elimination.
