Which of the following is not a recommended method for venous thromboembolism (VTE) prophylaxis in hospitalized patients?

Rationale: A. Bed rest: Prolonged immobility increases venous stasis, which is a major risk factor for VTE. Bed rest is not a preventive measure but rather a contributor to clot formation, making it inappropriate for VTE prophylaxis. B. Early ambulation: Encouraging patients to walk as soon as medically feasible promotes venous return and reduces stasis in the lower extremities. This is one of the most effective non-pharmacologic measures for preventing VTE in hospitalized patients. C. Subcutaneous low molecular weight heparin: Pharmacologic prophylaxis with LMWH helps prevent clot formation by reducing coagulation activity. It is widely recommended for patients at moderate to high risk of VTE. D. Intermittent pneumatic compression devices: These mechanical devices enhance venous return in the legs by rhythmic compression, reducing venous stasis. They are often used when anticoagulation therapy is contraindicated.
