護理師照顧一位初次處方舌下硝酸甘油片（Nitroglycerin）的病人。病人哪項說法表示需要進一步衛教？
A nurse is caring for a client with a new prescription for nitroglycerin sublingual tablets. Which statement by the client indicates a need for further teaching?
- AI will take one tablet every 15 minutes until the pain stops.✓ 正解我會每 15 分鐘服用一片，直到疼痛停止
- BI should feel a slight tingling sensation under my tongue.我應該會感覺到舌下有輕微的刺痛感
- CI will keep the tablets in the original dark glass bottle.我會將藥片保存在原裝的深色玻璃瓶中
- DI will sit down before taking the medication.我會在服藥前坐下
舌下硝酸甘油的正確用法是：每 5 分鐘服用一次，最多 3 次。若服用第 1 劑後症狀未緩解甚至惡化，應立即就醫（撥打 911/119）。每 15 分鐘服藥會延誤急性心肌梗塞的治療時機。藥物應避光儲存，且服用時因血管擴張常有刺痛感及低血壓風險，故應坐下。
The correct method for using sublingual nitroglycerin is to take one tablet every 5 minutes for up to 3 doses. If chest pain is not relieved or worsens after the first dose, the client should seek emergency care immediately (call 911/119). Taking the medication every 15 minutes delays treatment of acute myocardial infarction. The medication should be stored away from light, and the client should sit down before taking it because of the vasodilation-related risk of tingling and orthostatic hypotension.
美國 NCLEX 指引強調第一劑無效後應先打緊急電話再吃第二劑；台灣教材有時仍教導吃完三劑無效再就醫，應以最新指引為準。
