A patient has had a cast placed for the treatment of a humeral fracture. The nurse's most recent assessment shows signs and symptoms of compartment syndrome. What is the nurse's most appropriate action? a) Assess the patient's joint function symmetrically. b) Arrange for a STAT assessment of the patient's serum calcium levels. c) Perform active range of motion exercises. d) Contact the primary care provider immediately.
d) Contact the primary care provider immediately. This major neurovascular problem is caused by pressure within a muscle compartment that increases to such an extent that microcirculation diminishes, leading to nerve and muscle anoxia and necrosis. Function can be permanently lost if the anoxic situation continues for longer than 6 hours. Therefore, immediate medical care is a priority over further nursing assessment. Assessment of calcium levels is unnecessary.
