護理師教導病人自行皮下注射胰島素。哪項說明是正確的？
A nurse is teaching a client about self-administration of subcutaneous insulin. Which instruction is correct?
- AMassage the injection site after administration注射後按摩注射部位
- BUse a 1-inch needle for the injection使用 1 吋針頭進行注射
- CInject the insulin into the same site to ensure consistent absorption將胰島素注射到同一部位以確保吸收一致
- DRotate injection sites within an anatomical region✓ 正解在解剖區域內輪替注射部位

胰島素皮下注射的關鍵在於輪替部位（Site rotation），以預防脂肪增生（Lipohypertrophy）或萎縮，這些病變會改變胰島素的吸收速率，導致血糖不穩定。此外，注射後不應按摩，因為按摩會增加局部血流，導致胰島素吸收過快而引發低血糖。針頭長度需根據病人體型選擇，通常為短針以確保進入皮下組織。
Site rotation is key in subcutaneous insulin administration because it prevents lipohypertrophy or atrophy, which alters absorption and destabilizes blood glucose. Massage after injection should be avoided as it increases local blood flow and accelerates insulin absorption, risking hypoglycemia. Needle length is chosen by body size, typically a short needle, to ensure subcutaneous delivery.
