Q1. How should the nurse interpret the overall pattern?護理師應如何解讀整體型態？

Stable therapeutic response穩定的治療反應 Expected isolated fine tremor預期的單獨細顫 Primary anxiety without medication involvement原發性焦慮，與藥物無關 Progressive lithium toxicity from volume depletion and reduced renal clearance因體液容積耗竭與腎臟清除率降低導致的進行性鋰鹽毒性

Q2. What is the priority response?優先處置為何？

Hold lithium, obtain urgent medical evaluation, and begin indicated isotonic fluid and monitoring support停用鋰鹽、取得緊急醫療評估，並開始適當的等張輸液與監測支持 Give the next lithium dose with food隨餐給予下一劑鋰鹽 Administer more ibuprofen for discomfort給予更多 ibuprofen 以緩解不適 Restrict sodium and fluid限制鈉與水分

Q3. Which ongoing assessment set is most important?哪一組持續評估最為重要？

Skin testing and visual acuity only僅皮膚測試與視力 Daily weight without laboratory follow-up每日體重，無需實驗室追蹤 Neurologic status, renal function, electrolytes, serial lithium levels, and cardiac status神經狀態、腎功能、電解質、系列鋰鹽濃度與心臟狀態 Bowel sounds only after every meal每餐後僅聽腸音
