You have been called for a male worker complaining of arm pain. At the scene, the 31-year-old patient states that his arm was crushed between two heavy boxes that shifted while being stacked by a forklift. He had minimal pain at that time, but now his right forearm is swollen and painful, especially with movement. The patient also states that the arm and fingers feel as if they are "asleep." You note decreased strength to the arm and a radial pulse that is weak when compared to the left arm. There is no deformity to the arm and the skin is intact, although hard on palpation. Vital signs are pulse 88 beats/min, respiration 18 breaths/min, and blood pressure 134/76 mmHg. Given these assessment findings, the EMT should be suspicious of:

A) Compartment syndrome
B) Subclinical fracture
C) Hemorrhagic shock
D) Ischemic stroke

A) Compartment syndrome
