For a patient with a femur fracture, which order requires urgent action from the nurse to prevent complications?

In the case of a patient with a femur fracture, the use of a sequential compression device on the unaffected leg is a critical intervention that requires urgent action. This device is designed to promote venous return and prevent the development of deep vein thrombosis (DVT), which is a significant risk in patients with lower extremity fractures due to reduced mobility and potential immobilization.

The femur is a large bone, and fractures in this area can lead to complications such as DVT or pulmonary embolism, particularly if the patient is unable to move their lower limb effectively. By applying a sequential compression device, the nurse helps ensure proper blood flow and minimizes the likelihood of thrombus formation, thereby addressing potential complications proactively.

Other options, while important for the overall care of the patient, do not carry the same level of urgency in the context of preventing immediate complications related to the fracture. Ice pack applications help with swelling and pain management, physiotherapy sessions are important for rehabilitation but are typically scheduled for later, and regular pain assessments are essential for monitoring but do not directly prevent complications.
