Final answer:
Nursing management of an immobilized lower extremity involves strategies such as closed reduction and immobilization with a cast, splint, or brace to promote healing.
Step-by-step explanation:
When managing an immobilized lower extremity, nursing management involves several strategies to prevent complications and promote healing.
Firstly, it is important to ensure proper alignment of the broken bone. In some cases, closed reduction can be performed, which is a manual manipulation of the bone to set it back into its natural position without the need for surgery.
Additionally, immobilization is crucial to allow the bone to heal. This can be achieved through the use of a cast, splint, or brace, which prevents movement and maintains stability.
