護理師正在收納一位因化療而有嚴重噁心嘔吐，無法口服進食的病人。護理師應優先執行何種措施？
A nurse is admitting a client with severe nausea and vomiting due to chemotherapy. The client is unable to tolerate oral intake. Which intervention should the nurse prioritize?
- AOffer bland foods提供清淡食物
- BAdminister prescribed antiemetics✓ 正解給予處方止吐藥
- CProvide small, frequent sips of clear liquids提供少量多次的清澈液體啜飲
- DInitiate intravenous fluid hydration開始靜脈輸液補水
化療引起的噁心嘔吐（Chemotherapy-Induced Nausea and Vomiting, CINV）若不處理，會導致嚴重的電解質失衡與脫水。止吐藥（Antiemetics）應在病人無法口服時優先使用（如靜脈注射），以打破噁心-嘔吐的惡性循環，使病人恢復口服藥物與水分的能力。這是臨床護理中的優先順序（Prioritization），即先處理導致病人無法維持基本生理需求（口服）的症狀。
Chemotherapy-Induced Nausea and Vomiting (CINV), if untreated, can lead to severe electrolyte imbalance and dehydration. Antiemetics should be administered first when the client is unable to tolerate oral intake (e.g., via IV) to break the nausea-vomiting cycle, allowing the client to resume oral medications and fluid intake. This reflects the principle of prioritization in clinical nursing—first addressing the symptoms that prevent the client from meeting basic physiological needs (oral intake).
