The paramedics assess a three-year-old boy who is sitting on his mother's lap while she supports his arm, which is bent at the elbow and placed across his chest. The paramedic confirms that there are no cervical spine considerations; however, the wrist is painful, red, and swollen. Circulation is intact peripherally. Which of the following management options for the wrist is most appropriate?
a. Apply a rigid splint in the position found and secure the limb to the boy's body
b. Do not splint the wrist since the mother is providing adequate support to the limb
c. Secure the arm to the chest by using a broad bandage made from a triangular bandage
d. Straighten the limb so that a rigid splint can be applied from above the elbow to below the fingertips
