What kind of support may be prescribed for an obese pregnant client to prevent thromboembolism?

For an obese pregnant client, thromboembolism stockings or sequential compression devices represent a proactive approach to reducing the risk of thromboembolism. These support measures work by promoting venous return from the lower extremities, thereby decreasing the likelihood of blood clots forming. Obesity is a known risk factor for venous thromboembolism due to increased pressure on the pelvic veins and potential impairments to blood flow.

Thromboembolism stockings provide graduated compression which can help to enhance circulation and prevent blood pooling in the legs. Sequential compression devices additionally use intermittent pneumatic compression to stimulate blood flow in the calves. Both methods are evidence-based interventions commonly recommended in clinical practice to safeguard against thrombotic events, especially in high-risk populations such as obese pregnant women.

In contrast, other options may not be appropriate or effective; the idea that no support is necessary does not account for the increased risk present in obesity, while oral anticoagulants are usually not preferred in pregnant women due to potential risks to the fetus. Relying solely on bed rest is also inadequate as it doesn't actively address the underlying risk factors associated with thromboembolism in this population.
