Caprinivte risk score is correct.

The correct risk score for moderate risk is 3-4.

Caprini VTE risk assessment model is one of the most commonly used risk assessment tools for venous thromboembolism (VTE) in clinic, which is suitable for surgical inpatients. According to the patient's medical history, physical examination and laboratory examination, the model evaluates the VTE risk of patients and divides them into low risk, medium risk and high risk groups.

Caprini RAM can help clinicians better understand the VTE risk of patients and provide evidence for prevention and treatment. VTE generally refers to venous thromboembolism, and its symptoms usually include chest pain, dyspnea and chest tightness.

Swelling and edema appear in limbs, the difference in peripheral diameter of lower limbs is greater than 1cm, leg pain or tenderness, skin temperature rising, skin color of lower limbs turning red or blue, venous gangrene of limbs, and even symptoms such as shock in severe cases. These symptoms may vary from person to person and need to be determined by a doctor's diagnosis.

Preventive measures for VTE:

1, physical prevention: mainly carry out lower limb movements such as legs and feet, and carry out lower limb activities.

2. Drug prevention: ensure the daily liquid intake of pregnant women and prevent dehydration. If pregnant women have obvious VTE high-risk symptoms, low molecular weight heparin can be used to prevent thrombotic diseases.

3. Quit smoking: control the primary disease and control blood pressure.

4. Early activities of getting out of bed: such as passive exercise and active exercise.

5, mechanical prevention: such as the use of pneumatic compression or grading compression socks.
