After immobilizing an extremity fracture, which step should a paramedic perform last?

After immobilizing an extremity fracture, it is essential to assess the distal motor, sensory, and perfusion functions last to ensure that the splinting process has not adversely affected these critical functions. This assessment is vital for evaluating the status of circulation and nerve function after stabilization has been completed, confirming that the immobilization does not compromise these components.

Performing this assessment as the final step allows the paramedic to ensure that any potential complications from the splint application, such as reduced blood flow or nerve impairment, can be promptly identified and addressed. This step is crucial as it provides a point of reference for future evaluations, should changes in the patient's condition occur. By checking these functions last, the caregiver can measure the effectiveness of their immobilization technique and adjust as necessary to protect the patient's well-being.

The other options, while important, should occur before this assessment. Ensuring the splint is applied tightly guarantees stability, placing the hand in the position of function helps maintain proper alignment, and positioning the immobilized extremity below heart level aids in reducing swelling and promoting optimal circulation. All these steps should be accomplished prior to the final assessment of distal functions to create a comprehensive approach to injury management.
