Why do you think not assess motor, sensory, and circulatory function before and after splinting would be a critical fail?

In fracture patient, splinting is beneficial as it could prevent damage to the vascular and nerve tissue by immobilizing it. But splinting is also dangerous. To immobilize the extremity, splint needs to be put with enough force.  This force often can cause damage as it could block the arteries that run in the extremity, causing ischemia. 
It is important to do the assessment before and after splint to make sure the splint doesn't cause damage to the patient.
