A triangular bandage is being applied for stabilization. Which diagnosis would be the MOST likely based on this type of bandage?

• A. Lymphedema
• B. Shoulder subluxation
• C. Transtibial amputation
• D. Lateral ankle sprain

Answer: (D)

Triangular bandages are a quick, versatile way to immobilize an injured limb by securing a splint in place or creating a simple sling to limit movement. When a bandage is used for stabilization on a lower extremity, it is most commonly applied to immobilize an ankle injury to prevent further motion and reduce pain and swelling. A lateral ankle sprain fits this scenario best, as immobilizing the ankle with a bandage and splint is a typical first-aid approach. Lymphedema involves chronic swelling managed with compression garments rather than acute immobilization. A transtibial amputation relies on stump shaping and compression bandaging rather than a simple triangular bandage for stabilization. Shoulder subluxation is usually addressed with an arm sling, but the context of using a triangular bandage to stabilize an ankle makes the ankle sprain the most likely diagnosis.
