The nurse is conducting a community class on the prevention of varicose veins. The nurse discusses which of the following with the class?
1. Avoid long periods of standing or sitting in one position.
2. Gaining weight may help with minimizing risks of varicose veins.
3. Place the feet in a dependent position to help with circulation.
4. Avoid exercise such as walking that might increase stress on the legs.
Avoid long periods of standing or sitting in one position.
Rationale: The nurse should advise the class to avoid any activity that will create pooling of the venous system, such as sitting or standing for extended periods of time. The client should also lose weight if appropriate, not gain weight. Placing the feet in a dependent position will help with arterial circulation, not venous. Intermittent exercise will help increase venous return.
