護理師準備靜脈輸注氯化鉀。下列哪項評估是最優先的？
A nurse is preparing to administer potassium chloride IV. Which assessment is the highest priority?
- AUrine output✓ 正解尿量
- BRecent blood pressure reading最近的血壓讀數
- CPeripheral IV site integrity周邊靜脈注射點完整性
- DSerum magnesium level血清鎂濃度
鉀離子（Potassium）主要經由腎臟排泄。給予靜脈輸注鉀離子前，必須確認病人的腎功能是否正常。若病人處於少尿（Oliguria）或無尿狀態，給予鉀補充會導致血鉀快速升高，引發致命性的高血鉀症（Hyperkalemia），進而導致心律不整或心跳停止。在 NCLEX 考試中，處理潛在藥物毒性時，生理排泄功能評估永遠優於給藥途徑的檢查。
Potassium is excreted primarily by the kidneys. Before administering intravenous potassium, the nurse must verify that the client's renal function is adequate. If the client is oliguric or anuric, potassium replacement can cause a rapid rise in serum potassium, leading to life-threatening hyperkalemia and resulting arrhythmias or cardiac arrest. On the NCLEX, when addressing potential medication toxicity, assessment of physiological excretion always takes precedence over inspection of the administration route.
