Compression Therapy Practice Test 2026 – Complete Exam Prep Guide

Compression therapy reduces venous pooling by applying external pressure, which helps the calf muscle pump and promotes venous return. This lowers the chance of clot formation, but it doesn’t address all risk factors for DVT. DVT risk comes from multiple factors—stasis, hypercoagulability, and vessel injury—so improving flow alone isn’t enough to prevent every clot. The most effective approach is multimodal: use compression alongside other prophylaxis such as pharmacologic anticoagulation (when not contraindicated) and encouraging movement or ambulation. By tackling different parts of the risk, the overall protection is greater than using compression alone. Statements claiming compression alone prevents DVT, has no effect, or cures DVT aren’t accurate.
