A nurse is caring for a client who is 6 hr postoperative following application of an external fixator for a tibial fracture. Which of the following actions should the nurse take?

After application of an external fixator for a tibial fracture, neurovascular assessment is a priority to detect complications such as compartment syndrome, impaired circulation, or nerve compression. The nurse must frequently assess circulation, sensation, movement, pain, and skin temperature of the affected extremity. Early identification of compromised blood flow helps prevent permanent tissue damage. Postoperative care also focuses on preventing infection and maintaining proper device stability. A. Maintaining the affected extremity in a dependent position is incorrect because the extremity is usually elevated above heart level to reduce swelling and promote venous return. A dependent position can increase edema, pain, and pressure within the tissues, which may worsen circulation and increase the risk of compartment syndrome. B. Adjusting the clamps on the fixator frame is not a nursing responsibility and should only be done by the orthopedic provider. Manipulating the frame can disrupt bone alignment, compromise healing, and increase the risk of injury. The nurse should monitor the device but not alter its structure. C. Wrapping sterile gauze on the sharp point of the pins is not appropriate because the pin ends should remain visible for inspection and should not be covered unnecessarily unless specifically ordered. Routine pin site care focuses on preventing infection around the insertion site rather than covering the external hardware tips. D. Palpating the dorsalis pedis pulse is the correct action because it helps assess distal circulation and detect early signs of vascular compromise after surgery. Reduced or absent pulses may indicate swelling, compartment syndrome, or impaired arterial blood flow. Frequent neurovascular checks are essential in the immediate postoperative period following tibial fracture fixation.
