Which client is least at risk of a thromboembolic event?

A person who has a broken foot is least at risk of a thromboembolic event compared to the other options. While any injury can raise concerns about mobility and circulation, a broken foot typically encourages some degree of activity, such as using crutches or a walking boot, which can help maintain blood flow.

On the other hand, individuals with a sedentary lifestyle are at an increased risk for venous thromboembolism due to prolonged periods of immobility, which can lead to sluggish blood flow in the veins. Those with a history of deep vein thrombosis (DVT) are at a heightened risk for future thromboembolic events since previous blood clots predispose individuals to recurring clots. Similarly, major surgery often necessitates significant periods of immobility and can provoke hypercoagulability in the patient, thereby increasing the risk for thromboembolic events during recovery.

In sum, the dynamics surrounding mobility and blood flow associated with the broken foot, despite being an injury, generally place this individual at a lower risk for thromboembolic events than those listed in the other scenarios.
