A44-year-old female who is on her feet for the duration of her entire work week has developed varicose veins in her legs. what teaching point would her care provider be most justified in emphasizing to the woman? a. "once you have varicose veins, there's little that can be done to reverse them." b. "the use of blood thinner medications will likely relieve the backflow that is causing your varicose veins." c. "your varicose veins are likely a consequence of an existing cardiac problem." d. "if you're able to stay off your feet and wear tight stockings, normal vein tone can be reestablished."

The right answer is A.

In case of venous insufficiency, there are treatments that can relieve the pain and feeling of heavy legs, often associated with varicose veins.

Two types of treatments are possible:

*The elastic compression by stockings or bands: it is indicated as soon as the first symptoms of varicose veins appear. But it is a symptomatic treatment, which has no action on varicose veins already installed.

*Veinotonic drugs: they relieve symptoms, but they have no action on the evolution of varicose veins.

correct answer is option a.
