Final answer:
Caring for a patient at risk of developing DVT involves the use of elastic stockings, sequential compression devices, and teaching leg exercises. Elevation of the extremity can also be beneficial, yet fluid intake should not usually be limited.
Step-by-step explanation:
When caring for a patient at risk of developing deep vein thrombosis (DVT), several precautionary measures can be taken. Firstly, the application of elastic stockings helps maintain continuous pressure in the legs, promoting blood circulation and reducing the likelihood of clot formation. Secondly, to further prevent blood pooling and enhance circulation, sequential compression devices can be utilized. Lastly, it's important to instruct the patient on leg exercises that can be performed regularly, even when bedridden or sitting for extended periods, to maintain proper blood flow.
Limited fluid intake is generally not a preventive measure for DVT, and in many cases, maintaining adequate hydration is essential unless contraindicated. Elevation of the extremity can aid in decreasing swelling and improving venous return, and thus can be part of the care plan, always considering the patient's condition and mobility.
