Participants in the 5E program group will receive 7-day nursing interventions.

Participants in the control group will receive 7-day usual care interventions, including health education regarding signs and symptoms of venous thromboembolism and IPC use if the participants experienced muscle power as grade 0.

Participants in the 5E program group will receive 7-day nursing interventions including

• Education: health education regarding venous thromboembolism prevention
• Elevation: leg elevation of 10-20 degrees
• Exercise: ankle exercises
• Enough fluid: adequate fluid uptake
• Early application of intermittent pneumatic compression (IPC): IPC use within 48 hours after admission

The diagnosis of venous thromboembolism is confirmed by a Doppler ultrasound scan of the femoral vein and popliteal vein by a physician working at the study site. The physician will record the results in the data record form.

The Well's Score for deep venous thrombosis (DVT) includes clinical parameters: active cancer or palliative (+1), paralysis (+1), recently bedridden for more than 3 days (+1), localized tenderness (+1), entire leg swelling (+1), calf swelling more than 3 cm compared with asymptomatic leg (+1), pitting edema (+1), previous DVT documented (+1), collateral superficial veins (non-varicose) (+1), and alternative diagnosis (-2).

The Modified Well's Score for pulmonary embolism (PE) includes the following criteria: clinical signs and symptoms of DVT (3); an alternative diagnosis is less likely than PE (3); a heart rate greater than 100 (1.5); immobilization for 3 or more consecutive days (1.5); previous objectively diagnosed PE or DVT (1.5); hemoptysis (1); and malignancy (1).
