護理師準備為低血鉀病人靜脈輸注氯化鉀。下列何者為優先評估事項？
A nurse is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which of the following is the priority assessment?
- ACheck the client's blood pressure測量病人的血壓
- BObserve for signs of peripheral edema觀察周邊水腫跡象
- CAsk about the client's preference for oral medications詢問病人對口服藥物的偏好
- DAssess the client's hourly urine output✓ 正解評估病人的每小時尿量
靜脈輸注氯化鉀（KCl）具有潛在致命危險，必須嚴格控管。鉀離子主要透過腎臟排泄，若病人無尿或少尿（< 30 mL/hr），輸注鉀離子會迅速導致高血鉀（Hyperkalemia），進而引發心律不整甚至心跳停止。因此，在給藥前確認腎臟功能與排尿量是絕對優先事項。護理師應確保輸注速度適當，並嚴禁將 KCl 作為靜脈推注（IV push），必須稀釋並透過輸液幫浦給予。
Intravenous potassium chloride (KCl) administration carries a potentially fatal risk and must be strictly controlled. Potassium is primarily excreted by the kidneys; if the client is anuric or oliguric (< 30 mL/hr), infusing potassium will rapidly lead to hyperkalemia, which can precipitate cardiac dysrhythmias and even cardiac arrest. Therefore, confirming renal function and urine output before administration is the absolute priority. The nurse should ensure an appropriate infusion rate and must never administer KCl as an IV push; it must be diluted and delivered via an infusion pump.
