Prophylactic measure DVT includes –
**Core Concept**
Deep vein thrombosis (DVT) prophylaxis involves measures to prevent the formation of venous thrombi in patients at high risk. Effective prophylaxis requires a combination of mechanical and pharmacological interventions to minimize the risk of thromboembolic events.
**Why the Correct Answer is Right**
The use of low molecular weight heparin (LMWH) is a cornerstone of DVT prophylaxis in hospitalized patients at high risk of venous thromboembolism. LMWH works by inhibiting Factor Xa and thrombin, thereby preventing the formation of fibrin clots. It is particularly useful in patients undergoing major orthopedic surgery, trauma, or with severe mobility impairment. The efficacy of LMWH in preventing DVT has been demonstrated in numerous clinical trials, making it a recommended prophylactic measure.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a particular drug or intervention, making it a vague and non-specific choice.
**Option B:** This option is incorrect as it does not mention a widely accepted prophylactic measure for DVT. While compression stockings may provide some benefit, they are not considered a primary prophylactic measure.
**Option C:** This option is incorrect as it is a treatment for established DVT, not a prophylactic measure.
**Clinical Pearl / High-Yield Fact**
When initiating DVT prophylaxis, it is essential to consider the patient's risk factors, including immobility, surgery, and underlying medical conditions. A combination of mechanical and pharmacological interventions is often necessary to minimize the risk of thromboembolic events.
**Correct Answer: D. Low molecular weight heparin.**
