護理師指導病人服用碳酸鋰（Lithium）。下列哪些病人敘述顯示其已正確理解？（選所有適合的）
A nurse is teaching a client about lithium carbonate therapy. Which statements by the client indicate a correct understanding? (Select all that apply.)
- AI should maintain a consistent daily intake of salt✓ 正解我應該保持每日恆定的鹽分攝取量
- BI will drink 2-3 liters of fluid every day✓ 正解我每天會喝 2-3 公升的水
- CI should stop taking the drug if I feel nauseated如果我感到噁心，我應該停止服藥
- DI need to have my blood levels checked regularly✓ 正解我需要定期接受血液濃度檢測
- EI can use ibuprofen for headache pain我可以用布洛芬來緩解頭痛
鋰鹽治療窗狹窄，對鈉與水分平衡極度敏感。維持鈉攝取量恆定可防止鋰濃度波動；補充足夠水分有助於腎臟代謝。需定期抽血監測鋰濃度以防中毒。C選項：噁心為常見副作用，不應自行停藥，應告知醫師調整。E選項：NSAIDs（如布洛芬）會減少鋰排出，增加中毒風險，應避免使用。
Lithium has a narrow therapeutic index (0.6-1.2 mEq/L for maintenance) and is highly sensitive to sodium and water balance. Clients must maintain consistent daily sodium intake and drink 2-3 L of fluid daily because sodium depletion or dehydration increases lithium levels and toxicity risk. Regular serum lithium monitoring is mandatory. Nausea is common but the client should not self-discontinue; NSAIDs (e.g., ibuprofen) reduce renal lithium clearance and significantly increase toxicity risk—acetaminophen is preferred.
兩地均強調鋰鹽與電解質的交互作用，但台灣對 NSAIDs 與鋰鹽的藥物警示在衛教中相對重要。
