Ontario Clinical Practice Exam Prep: Practice Test & Study Guide

Early mobilization post-operatively is crucial in preventing Pulmonary Embolism (PE) because it helps maintain circulation and reduces the risk of venous thromboembolism (VTE). When patients remain immobile for extended periods, such as after surgery, blood flow can become sluggish, particularly in the lower extremities. This stagnation increases the likelihood of thrombus formation, which can dislodge and lead to a PE.

Encouraging patients to mobilize early after surgery promotes blood flow and reduces the risk of clot development. Activities as simple as sitting up, dangling the legs, and gradually progressing to walking can significantly help in this regard.

While other preventive measures, such as anticoagulants, increased fluid intake, and oxygen therapy, play important roles in the broader context of patient care, early mobilization specifically addresses the mechanics of blood flow and clot formation, making it a key strategy for preventing PE in post-operative patients.
