When immobilizing the limb of a fracture patient with no exposed bone ends, the immobilization should extend beyond the joints above and below the wound.

ANSWER · A

Extending beyond the joints above and below fixes both joints. This prevents fracture-end displacement and damage to blood vessels and nerves; nerve damage in particular is harder to treat than a simple fracture and can cause sensory or motor disorders. It also prevents fracture ends from piercing the skin and contaminating healing.
