一位低血鉀病人被醫囑給予靜脈鉀離子輸注。護理師在給藥前優先採取的行動為何？
A client with hypokalemia is prescribed an intravenous potassium infusion. Which priority action should the nurse take before administering the dose?
- ACheck the client's blood pressure檢查病患的血壓
- BObtain a baseline electrocardiogram取得基線心電圖
- CVerify the presence of urinary output✓ 正解確認是否有尿液排出
- DAssess the intravenous site for phlebitis評估靜脈穿刺處是否有靜脈炎
靜脈輸鉀首要條件是確保腎功能正常（尿量足夠），避免鉀離子堆積導致致死性高血鉀。即使心電圖異常也需先確認腎臟排泄功能。靜脈炎檢視與血壓評估雖重要，但相較於因腎衰竭導致的高血鉀致命性，確認腎功能為最高優先級。
The primary prerequisite for intravenous potassium administration is ensuring adequate renal function (adequate urine output) so that potassium does not accumulate and cause lethal hyperkalemia. Even when ECG findings are abnormal, renal excretory function must be confirmed first. Inspection for phlebitis and blood pressure assessment are also important, but compared with the lethal hyperkalemia that can result from renal failure, confirming renal function takes top priority.
美台臨床均嚴格要求輸鉀前須有尿量紀錄，美國護理師常需更嚴謹遵守『No Urine, No K』原則。
