護理師準備為一位上心室性心搏過速（SVT）病人施打 Adenosine 6 mg。護理師應如何給藥？
A nurse is preparing to administer adenosine 6 mg to a client with supraventricular tachycardia (SVT). How should the nurse administer this medication?
- AAdminister as a rapid bolus over 1 to 2 seconds followed by a saline flush✓ 正解在 1 至 2 秒內快速推注，隨後以生理食鹽水沖管
- BAdminister over 2 to 3 minutes using a slow IV push使用慢速靜脈推注，時間為 2 至 3 分鐘
- CDilute in 50 mL of normal saline and infuse via secondary tubing稀釋於 50 mL 生理食鹽水中，透過次要管路輸注
- DGive via the intramuscular route into a large muscle mass透過肌肉注射途徑注入大塊肌肉
Adenosine 的藥物半衰期極短（少於 10 秒）。為了使其能在代謝掉之前到達心臟發揮藥效，必須採取「極快速靜脈推注」（Rapid IV push），時間控制在 1-2 秒內。推注後應立即跟隨 20 mL 的生理食鹽水沖洗（Saline flush），並最好將給藥肢體抬高，以利用重力加速藥液進入循環。B 選項（慢推）會使藥物在到達心臟前就被完全代謝。C 選項（稀釋點滴）無效。D 選項（肌肉注射）完全錯誤。這題考的是護理師對藥物動力學與特殊給藥技術的掌握，這是處理致命性心律不整的關鍵技能。
Adenosine has an extremely short half-life (less than 10 seconds). To allow the drug to reach the heart before being metabolized, it must be administered as a rapid IV push within 1-2 seconds. Immediately afterward, it should be followed by a 20 mL normal saline flush, and ideally the administering extremity should be elevated so that gravity speeds the drug into the central circulation. Option B (slow push) results in the drug being fully metabolized before reaching the heart. Option C (diluted infusion) is ineffective. Option D (intramuscular injection) is completely incorrect. This item tests the nurse's mastery of pharmacokinetics and special drug-administration techniques, which is a critical skill in managing life-threatening dysrhythmias.
美國 NCLEX 與 ACLS 指引高度一致，強調「快速推注 + 抬高手臂」；台灣臨床通常由醫師親自推注 Adenosine，護理師負責備藥與沖水，但護理師仍需熟悉此特殊技術以協助急救。
