Final answer:
The priority nursing intervention for a patient with lower extremity fracture who complains of severe pain and tightness in his calf, minimally relieved by pain medications, would be to assess for signs of compartment syndrome.
Step-by-step explanation:
The priority nursing intervention for a patient with lower extremity fracture who complains of severe pain and tightness in his calf, minimally relieved by pain medications, would be to assess for signs of compartment syndrome.
Compartment syndrome is a serious condition in which increased pressure within a muscle compartment impairs blood flow, potentially leading to tissue damage and cell death. Symptoms of compartment syndrome include severe pain, tightness, swelling, and decreased sensation and function in the affected area.
Administering a muscle relaxant, applying a warm compress, and elevating the leg may provide some relief, but they do not address the underlying concern of compartment syndrome. Assessing for signs of compartment syndrome is crucial in order to promptly recognize and treat the condition.
