- AIf pain persists, I can take up to 5 tablets如果疼痛持續，我可以服用最多 5 錠
- BThe medication should be stored in the refrigerator藥物應存放在冰箱中

硝酸甘油（Nitroglycerin）舌下錠屬於揮發性藥物，極易受光、熱、濕氣影響而失去藥效。正確的保存方式為放置在原廠提供的深色玻璃瓶中，並確保瓶蓋緊閉。臨床上，護理師需教導病人若出現胸痛，應於舌下含服一錠，若 5 分鐘後無效，可每 5 分鐘服用一劑，最多 3 劑。若 3 劑後症狀未緩解，需立即就醫，而非持續服用。
Nitroglycerin sublingual tablets are volatile and are easily inactivated by light, heat, and moisture. The correct storage method is to keep them in the original dark glass bottle with the cap tightly closed. Clinically, the nurse should teach the client to place one tablet under the tongue if chest pain occurs; if there is no relief after 5 minutes, an additional dose may be taken every 5 minutes for a maximum of 3 doses. If symptoms are not relieved after 3 doses, the client must seek emergency medical care rather than continue taking the medication.
