護理師準備為一名 6 個月大的嬰兒進行肌肉注射。護理師應選擇哪個部位？
The nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site should the nurse use?
- AVastus lateralis muscle✓ 正解股外側肌
- BVentrogluteal muscle腹臀肌
- CDeltoid muscle三角肌
- DDorsogluteal muscle臀大肌
— Explanation · 中文詳解 —
對於 1 歲以下的嬰兒，股外側肌（Vastus lateralis）是肌肉注射的首選部位，因為該肌肉在發育初期最為發達，且避開了重要的神經與血管。臀大肌（Dorsogluteal）因有傷及坐骨神經的風險，在幼兒及嬰兒中是禁忌。
For infants younger than 1 year, the vastus lateralis is the preferred site for intramuscular injection because this muscle is the most developed in early infancy and avoids major nerves and blood vessels. The dorsogluteal site carries a risk of sciatic nerve injury and is contraindicated in young children and infants.
