護理師準備一位接受全膝關節置換術後出院的病人，下列哪項活動護理師應指導病人初期避免？
A nurse is preparing a client for discharge after a total knee replacement. Which activity should the nurse instruct the client to avoid initially?
- AApplying ice packs to the knee將冰敷包敷於膝蓋
- BClimbing stairs✓ 正解爬樓梯
- CPerforming prescribed range-of-motion exercises執行處方範圍之關節活動度運動
- DWalking with an assistive device使用輔具行走
全膝關節置換術（TKA）術後初期，關節穩定性尚未完全恢復，組織腫脹且疼痛感明顯。爬樓梯需要極高的股四頭肌力量以及膝關節彎曲度，對於剛手術的病人而言，這屬於高強度活動，極易導致關節發炎、脫位風險增加或過度疲勞。護理師應指導病人先行進行物理治療（PT）中的基礎復健與輔具行走，待評估肌力足夠後，再在治療師指導下學習正確的上下樓梯技巧。
In the early postoperative period after total knee arthroplasty (TKA), joint stability has not yet been fully restored, the tissues remain swollen, and pain is prominent. Climbing stairs requires substantial quadriceps strength and a high degree of knee flexion, which is a high-intensity activity for a client immediately postoperative and is highly likely to cause joint inflammation, increase the risk of dislocation, or cause excessive fatigue. The nurse should instruct the client to first engage in basic rehabilitation and assistive ambulation through physical therapy (PT) and to learn proper stair-climbing technique under therapist guidance only after sufficient strength has been demonstrated.
