護理師準備靜脈輸注氯化鉀，下列哪項評估是確保病人安全的優先事項？
A nurse is preparing to administer potassium chloride intravenously. Which of the following is the priority assessment to ensure client safety?
- AAssessing the client's skin turgor評估病人的皮膚彈性
- BMonitoring the client's hourly urine output✓ 正解監測病人的每小時尿量
- CEvaluating the client's respiratory rate評估病人的呼吸頻率
- DChecking the client's blood pressure檢查病人的血壓
給予鉀離子前，必須確認病人的腎功能是否正常，因為鉀離子主要透過腎臟代謝。若尿量低於 30 mL/hr，表示腎臟排泄功能受損，貿然給鉀會導致高血鉀危象。其他生理參數雖然重要，但不如尿量對鉀離子排除的臨床意義關鍵。
Before administering potassium, the nurse must confirm the client's renal function, because potassium is excreted primarily by the kidneys. If urine output is less than 30 mL/hr, renal excretory function is impaired, and giving potassium without correction could cause life-threatening hyperkalemia. Other physiologic parameters are important but are less clinically significant than urine output for safe potassium administration.
台美均嚴格要求鉀離子給藥前評估尿量，但在美國護理執業範圍中，若尿量不足，護理師可直接拒絕執行並回報，台灣護理師通常需與醫師確認後再依醫囑執行。
