A nurse is collecting data from a client who has a long-leg cast on his left leg and reports severe pain. Which of the following findings should the nurse identify as an indication that the client might have compartment syndrome? (Select all that apply.)

Compartment syndrome is a condition characterized by increased pressure within a closed anatomical space, such as a compartment in the leg. This increased pressure can compromise blood flow and nerve function. When assessing a client with a long-leg cast who reports severe pain, the nurse should be vigilant for signs and symptoms of compartment syndrome. Option a is a correct answer because pallor (paleness) in the exposed portion of the left foot may indicate compromised blood flow due to increased pressure within the compartment. Option b is a correct answer because the inability to move the left foot suggests impaired nerve function, which can be a sign of compartment syndrome. Option c is not a correct answer. Increased warmth is not typically associated with compartment syndrome; instead, it may suggest inflammation or infection. Option d is not a correct answer. Ecchymosis (bruising) is not typically associated with compartment syndrome, as it is more commonly observed in cases of injury or trauma. Option e is a correct answer because paresthesia (abnormal sensations like tingling or numbness) in the left foot can indicate nerve compression and is a potential symptom of compartment syndrome. By identifying the presence of pallor, inability to move the foot, and paresthesia, the nurse can recognize indications of compartment syndrome and take appropriate actions to address the condition promptly.
