A client with chronic kidney disease (CKD) has a serum phosphorus level of 5.8 mg/dL. Which action should the nurse take?
- AAdminister IV potassium chloride靜脈注射氯化鉀
- BEncourage increased intake of dairy products鼓勵增加乳製品的攝取
- CRestrict physical activity限制體力活動
- DAdminister a phosphate binder with meals✓ 正解進食時給予磷酸鹽結合劑
— Explanation · 中文詳解 —
慢性腎臟病（CKD）患者因腎功能衰竭，無法有效排出磷離子，導致高血磷（Hyperphosphatemia）。高血磷會引起副甲狀腺素分泌增加，導致骨質流失，並可能與鈣結合沉積在軟組織。磷結合劑（Phosphate binder）必須隨餐服用，以在腸道中與食物中的磷結合，減少吸收。這是 CKD 飲食控制的重要組成。
In clients with chronic kidney disease, phosphate binders should be administered with meals to bind dietary phosphorus in the gastrointestinal tract, thereby reducing its absorption. This intervention helps manage hyperphosphatemia, which can lead to secondary hyperparathyroidism and soft tissue calcification if left untreated.
