護理師準備對嬰兒進行肌肉注射，應選擇哪一個部位？
A nurse is preparing to administer an intramuscular injection to an infant. Which site should the nurse select?
- ADeltoid muscle三角肌
- BVastus lateralis✓ 正解股外側肌
- CVentrogluteal site腹臀區
- DDorsogluteal site背臀區
— Explanation · 中文詳解 —
嬰兒的肌肉發展尚未成熟，股外側肌（Vastus lateralis）位於大腿外側，體積最大且無大血管與神經經過，是嬰兒進行肌肉注射最安全且首選的位置。背臀部因坐骨神經損傷風險不建議使用，三角肌對嬰兒來說太小。
Infants' muscles are not yet fully developed; the vastus lateralis, located on the outer thigh, is the largest muscle mass without major blood vessels or nerves running through it, making it the safest and preferred site for intramuscular injection in infants. The dorsogluteal site is not recommended due to the risk of sciatic nerve injury, and the deltoid muscle is too small in infants.
