Explanation:
The correct option is 4) Arm. A soft pillow splint can be used to splint an injury to the arm. The arm, particularly the humerus, is prone to fractures from falls onto the hand or elbow, or direct blows. These injuries can include transverse, spiral, or impacted fractures where the distal portion of the humerus is driven into the proximal portion.
Furthermore, because the upper limb and its components, such as the shoulder joint, are engaged extensively in activities like throwing, swimming, or racquet sports, injuries in these areas are common. A soft pillow splint would therefore be most useful and appropriate for injuries to the arm, providing support and immobilization to facilitate healing.
