病人獲處方舌下含服硝酸甘油（Nitroglycerin）治療穩定型心絞痛，下列哪項指導正確？
A client is prescribed sublingual nitroglycerin for stable angina. Which instruction is correct?
- ASwallow the tablet with a full glass of water用一杯水吞服藥片
- BTake up to 3 tablets at 5-minute intervals if pain persists✓ 正解若疼痛持續，每 5 分鐘服用最多 3 顆藥片
- CChange position quickly after taking the medication服藥後迅速改變姿勢
- DStore the medication in the original plastic container將藥物存放在原廠塑膠容器中
舌下硝酸甘油（sublingual nitroglycerin）的標準使用指引：(1) 病人胸痛時讓藥錠於舌下溶解吸收（不可吞服，B 反方向）；(2) 標準劑量間隔為「每 5 分鐘 1 顆，最多 3 顆」（B 正解）；(3) 若 3 顆後胸痛未緩解需立即呼叫急救／撥 911；(4) 藥物對光與熱敏感，需保存在原裝深色玻璃瓶（C 為塑膠容器，錯誤）；(5) 給藥後會引起血管擴張造成姿勢性低血壓，需緩慢改變姿勢（D 反方向）。
Standard instructions for sublingual nitroglycerin: (1) when the client has chest pain, the tablet should be allowed to dissolve under the tongue for absorption (not swallowed; A is the reverse); (2) the standard dosing interval is 'one tablet every 5 minutes for up to 3 tablets' (B is correct); (3) if chest pain is not relieved after 3 tablets, emergency services (e.g., 911) must be activated immediately; (4) the drug is sensitive to light and heat and must be stored in its original dark glass bottle (C, plastic container, is incorrect); (5) administration causes vasodilation and orthostatic hypotension, so position changes must be made slowly (C is the reverse).
兩地衛教內容一致，均強調含服而非吞服的重要性。
