一位慢性腎臟病病人血鉀值為 6.2 mEq/L。護理師應指導病人避免攝取下列哪種食物？
A client with chronic kidney disease (CKD) has a serum potassium level of 6.2 mEq/L. Which food should the nurse instruct the client to avoid?
- AWhite rice白米飯
- BCranberry juice蔓越莓汁
- CBananas✓ 正解香蕉
- DApples蘋果
慢性腎臟病（Chronic Kidney Disease, CKD）病人因腎絲球過濾率下降，無法有效排出鉀離子，極易產生高血鉀（Hyperkalemia）。血鉀值 6.2 mEq/L 屬於危險範圍，可能導致致命的心律不整（Arrhythmias）。護理原則為限制高鉀食物攝取，香蕉為典型的高鉀水果，必須避免。臨床思路應優先評估心電圖（ECG）變化，並監測血鉀水平。
Patients with chronic kidney disease (CKD) have a decreased glomerular filtration rate and cannot effectively excrete potassium ions, easily leading to hyperkalemia. A potassium level of 6.2 mEq/L is in the dangerous range and may cause fatal arrhythmias. The nursing principle is to restrict the intake of high-potassium foods; bananas are a classic high-potassium fruit and must be avoided. Clinical reasoning should prioritize evaluating ECG changes and monitoring potassium levels.
