A nurse is collecting data from a client who has a long leg cast on his left leg. Which of the following findings is the priority?

A. Diminished pulses on the affected extremity. Reduced pulses suggest impaired circulation, which may indicate compartment syndrome, a serious complication where increased pressure restricts blood flow. Without prompt intervention, this can lead to tissue damage or limb loss. The nurse should assess for additional signs such as pallor, paresthesia, and unrelieved pain and notify the provider immediately. B. One fingerbreadth of space between the cast and the skin. This is an expected finding, as having a small space between the cast and skin allows for proper circulation and prevents excessive pressure that could lead to skin breakdown. The cast should be snug but not too tight to allow for swelling that may occur after injury or surgery. However, this does not require immediate intervention. C. Client report of muscle spasms of the left leg. Muscle spasms are common in clients with immobilized limbs due to muscle fatigue, positioning, or nerve irritation. While uncomfortable, they do not indicate an emergency. The nurse can suggest gentle repositioning, relaxation techniques, or prescribed muscle relaxants to alleviate discomfort. D. Ecchymosis on the inner left thigh. Bruising is a normal response to trauma and does not necessarily indicate a severe complication. It should be monitored for changes such as increasing size, pain, or signs of infection, but it does not take priority over assessing circulation and preventing limb-threatening complications.
