Final answer:
The adolescent is at the highest risk for developing compartment syndrome.
Step-by-step explanation:
The adolescent in this case is at the highest risk for developing compartment syndrome. Compartment syndrome occurs when there is increased pressure within a muscle compartment, leading to compromised blood flow and potential tissue damage. The adolescent's symptoms, such as paresthesia (abnormal sensations) and immobility, are indicative of compartment syndrome.
