A client recently underwent surgery and is at risk of developing deep vein thrombosis (DVT). What preventive measure should the nurse recommend to the client?
Performing isometric exercises hourly.
Wearing graduated compression stockings.
Limiting fluid intake to reduce blood volume.
Avoiding elevation of the legs while resting.
The Correct Answer is B
A) This choice is incorrect because while isometric exercises can promote blood flow, the recommended preventive measure for DVT is wearing graduated compression stockings. Exercises alone may not be sufficient to prevent clot formation.
B) This choice is correct. Graduated compression stockings apply pressure to the lower extremities, improving blood flow and reducing the risk of stasis and clot formation. They are commonly used as a preventive measure for clients at risk of DVT, particularly after surgery or during prolonged immobility.
C) This choice is incorrect because limiting fluid intake is not a preventive measure for DVT and may not be safe or appropriate for all clients. Adequate hydration is essential to maintain blood volume and circulation.
D) This choice is incorrect because elevating the legs while resting is a recommended measure to improve blood flow and reduce edema, which can be beneficial. However, wearing graduated compression stockings is a more specific preventive measure for DVT.

Correct Answer is C
Explanation
A) This choice is incorrect because fasting is not necessary before a venous Doppler ultrasound. The client can eat and drink normally before the test.
B) This choice is incorrect because the client should continue to take prescribed medications as usual unless otherwise instructed by the healthcare provider. Medications that thin the blood, such as anticoagulants, may not be stopped before the test.
C) This choice is correct. The client should wear loose-fitting clothing that can be easily removed to allow access to the affected area during the ultrasound. This facilitates the ultrasound technician's ability to perform the test accurately.
D) This choice is incorrect because contrast dye is not typically used in a venous Doppler ultrasound. Contrast venography may involve the use of contrast dye, but not Doppler ultrasound.
Questions
Correct Answer is B
Explanation
A) This choice is incorrect because anticoagulants do not dissolve existing blood clots in the veins. They prevent further clot formation and allow the body's natural mechanisms to dissolve the clot over time.
B) This choice is correct. Anticoagulants work by inhibiting the clotting factors in the blood, which prevents the formation of new blood clots and reduces the risk of the existing clot enlarging or causing additional complications.
C) This choice is incorrect because while anticoagulants may indirectly reduce pain and inflammation by preventing further clot formation, their primary action is to prevent clotting, not directly reduce pain and inflammation associated with DVT.
D) This choice is incorrect because while anticoagulants can improve blood flow by preventing clot formation, they do not directly "improve" blood flow to the affected limb.
