慢性腎臟病病人血磷過高，哪項飲食指導最重要？
A client with chronic kidney disease (CKD) has a high phosphate level. Which dietary instruction is most important?
- AAvoid all dairy products避免所有乳製品
- BTake phosphate binders with meals✓ 正解隨餐服用磷酸鹽結合劑
- CIncrease daily water intake增加每日水分攝取
- DConsume only plant-based proteins僅攝取植物性蛋白質
慢性腎臟病（CKD）病人因腎臟排磷功能受損，血液中磷離子濃度升高（Hyperphosphatemia），這會導致鈣磷失衡，進而引發繼發性副甲狀腺機能亢進與骨質病變。磷結合劑（Phosphate Binders）的作用機轉是在腸道中與食物中的磷結合，形成不溶性的複合物隨糞便排出，從而減少磷的吸收。因此，必須隨餐服用才能發揮最大功效。
In chronic kidney disease (CKD), impaired renal excretion of phosphorus leads to elevated serum phosphate levels (hyperphosphatemia), resulting in calcium-phosphorus imbalance and subsequent secondary hyperparathyroidism and bone disease. Phosphate binders work by binding dietary phosphorus in the intestine to form insoluble complexes that are eliminated in the stool, thereby reducing phosphorus absorption. For maximum effect, they must therefore be taken with meals.
