護理師指導病人舌下含服硝酸甘油（Nitroglycerin）治療穩定型心絞痛，下列敘述哪些顯示需要再衛教？（選所有適合的）
A nurse is teaching a client about the use of sublingual nitroglycerin for stable angina. Which of the following client statements indicates a need for further teaching? (Select all that apply.)
- AI should keep the medication in the original amber-colored bottle我應該將藥物保存在原廠琥珀色瓶中
- BIf chest pain persists after one tablet, I should wait 15 minutes before taking another✓ 正解如果服用一片後胸痛持續，我應該等待 15 分鐘再服用另一片
- CI should feel a tingling sensation under my tongue if the medication is effective如果藥物有效，我應該感覺舌下有刺痛感
- DI can store the tablets in my pocket to ensure they are available at all times✓ 正解我可以將藥片放在口袋裡，以確保隨時可用
- EI should call 911 if pain is not relieved after the first dose如果第一劑後疼痛未緩解，我應該撥打 911
硝酸甘油需存放在避光原瓶中，若含服時無刺痛感可能已失效。使用原則為：若含服一顆後 5 分鐘症狀未緩解，應立即撥打急救電話，並可每 5 分鐘含服第二、三顆（總共不超過三顆）。B 錯誤在於間隔時間過長，D 錯誤在於藥物對光熱敏感，不可隨身放在貼身口袋。
Nitroglycerin should be stored in its original amber bottle, and a lack of tingling under the tongue when taken may indicate that the medication has lost potency. The principle of use is: if symptoms do not resolve 5 minutes after the first sublingual tablet, call emergency services immediately; a second and third tablet may be taken at 5-minute intervals (no more than three tablets total). Option B is incorrect because the interval is too long, and option D is incorrect because the medication is sensitive to light and heat and should not be carried in a pocket close to the body.
美國衛教強調撥打 911，台灣建議撥打 119，兩者皆為即時救援機制。
