護理師向一位心臟衰竭病人提供出院指導。哪項指導最重要？
A nurse is reviewing discharge instructions for a client with heart failure. Which instruction is most important to include?
- ARestrict fluid intake to 1 liter per day每日液體攝取量限制在 1 公升
- BConsume a high-sodium diet攝取高鈉飲食
- CWeigh yourself daily at the same time✓ 正解每日固定時間測量體重
- DDiscontinue diuretics if feeling well感覺良好時停用利尿劑
心臟衰竭（Heart Failure）病人的照護核心在於體液平衡管理。由於心臟泵血功能受損，體液容易滯留導致周邊水腫或肺水腫，而體重監測是評估體液滯留最靈敏的指標。每日固定時間（通常為晨起排空膀胱後）、穿著相同衣物測量體重，能精確反映體液累積狀況。若 24 小時內體重增加 2-3 磅（約 0.9-1.4 公斤）或一週內增加 5 磅，即需回報醫師，這通常是臨床症狀惡化的前兆。其他選項如高鈉飲食會增加水分滯留，過度限水或擅自停藥則會干擾治療計畫，皆不利於病情控制。
Core care for heart failure clients centers on fluid balance management. Because of impaired cardiac pumping, fluid retention easily occurs causing peripheral or pulmonary edema. Daily weight monitoring is the most sensitive indicator of fluid retention. Weighing at the same time daily (typically after morning void), wearing similar clothing, allows accurate detection of fluid accumulation. A 2-3 lb gain in 24 hours or 5 lb in a week should be reported. High-sodium diet, over-restriction of fluids, or stopping diuretics independently are all counterproductive.
