✓ Correct answer: D. Amputation of the extremityAnswer: Amputation of the extremity Crush injuries that lead to extensive soft tissue damage, compromised circulation, and potential nerve involvement often necessitate amputation due to the severity of the damage and limited efficacy of grafts in such cases. While amputation might be necessary, it is not likely to be fatal if treated with amputation, as opposed to attempting skin and/or muscle grafts, which are generally ineffective for extensive crush injuries.
