A nurse is completing a neurovascular check for a client who had an open reduction internal fixation surgery. Which of the following findings should the nurse identify as possible manifestations of compartment syndrome? (Select all that apply.)

A. Altered sensation (paresthesia) in the toes is an early sign of compartment syndrome caused by nerve compression. B. Absence of pulse can indicate severe compartment syndrome with arterial compromise. C. Pain from compartment syndrome is not relieved by narcotics; severe, unrelenting pain is a hallmark symptom. D. Cool skin distal to the affected area indicates impaired perfusion, a complication of compartment syndrome. E. Capillary refill of 1 second is normal and does not indicate compromised circulation.
