護理師教導病人自行注射胰島素。下列何項說明病人理解輪替注射部位的重要性？
A nurse is teaching a client about self-administration of insulin. Which of the following indicates that the client understands the importance of rotation of injection sites?
- AIt ensures faster absorption of insulin確保胰島素吸收更快
- BIt prevents lipodystrophy✓ 正解預防脂質失養症
- CIt prevents allergic reactions預防過敏反應
- DIt decreases the chance of bruising減少瘀青的機會
胰島素需長期注射，若反覆在同一部位注射，會導致該處皮下組織發生纖維化或脂肪組織增生/萎縮，即「脂質失養症」（Lipodystrophy）。這不僅影響外觀，更嚴重的是會導致胰島素吸收不穩定，使血糖波動劇烈。因此，教育病人輪替注射部位（Rotation of injection sites）是確保藥物吸收率一致與維護皮下組織健康的關鍵。
Insulin requires long-term injection; repeated injection at the same site causes fibrosis or fatty hypertrophy/atrophy of the subcutaneous tissue, known as lipodystrophy. This not only affects appearance but, more importantly, leads to unstable insulin absorption and marked glycemic variability. Therefore, teaching the client to rotate injection sites is essential for ensuring consistent absorption and preserving the health of subcutaneous tissue.
