The question asks about the precautionary measure to observe when a participant sustains a straight elbow fracture during a stunt routine.
The correct answer is likely:
"Do not attempt to bend the elbow to apply a sling."
This precaution is essential to avoid worsening the injury. Attempting to move or manipulate the fractured area could cause further damage to the bones, nerves, or blood vessels. Instead, immobilize the arm as is, and seek medical assistance immediately.
