For peripheral venous disease, the nurse will teach the patient to do what in order to promote blood circulation?
Dangle the legs.
Sit in one position for prolonged hours.
Elevate the legs.
Stand in one position.
The Correct Answer is C
This is because elevating the legs can help reduce swelling and improve blood flow back to the heart by reducing the effects of gravity. Elevating the legs can also prevent blood from pooling in the veins and reduce the risk of blood clots.
Choice A is wrong because dangling the legs can increase swelling and pressure in the veins, which can worsen peripheral venous disease (PVD) symptoms and complications.
Choice B is wrong because sitting in one position for prolonged hours can impair blood circulation and increase the risk of blood clots, especially in the lower legs. People with PVD should avoid crossing their legs, wearing tight clothing, or sitting for long periods without moving.
Choice D is wrong because standing in one position can also increase swelling and pressure in the veins, which can lead to pain, ulcers, and skin changes. People with PVD should avoid standing for long periods without moving or changing positions.
Some additional information:
Peripheral venous disease (PVD) is a condition that affects blood flow in the veins and arteries outside of your heart and brain.
It can be caused by narrowing, blocking, or spasming of the blood vessels, or by blood clots in the veins. PVD can cause pain and fatigue, especially in the legs, and can lead to serious complications such as gangrene or amputation.
The most common cause of PVD is atherosclerosis, the buildup of plaque inside the artery wall.
Plaque reduces the amount of blood flow to the limbs and decreases the oxygen and nutrients available to the tissue. Other causes of PVD may include injury, infection, irregular anatomy of muscles or ligaments, or inflammation of the blood vessels.
The normal range of blood pressure in the veins is about 10 to 20 mmHg.
The normal range of oxygen saturation in the veins is about 60 to 80%.
The normal range of pulse rate in the veins is about 60 to 100 beats per minute.

Correct Answer is C
Explanation
Bile acid-binding resins are cholesterol-lowering agents that bind to bile acids in the intestine and prevent their reabsorption. This reduces the amount of bile acids available for cholesterol synthesis in the liver, which lowers the levels of LDL cholesterol in the blood. However, bile acids are also needed for the absorption of fat-soluble vitamins A, D, E, and K.Therefore, patients taking bile acid-binding resins may require supplements of these vitamins to prevent deficiency.
Choice A is wrong because nicotinic acid, or niacin, is a B vitamin that can lower cholesterol by limiting the production of fats in the liver.It does not affect the absorption of fat-soluble vitamins.
Choice B is wrong because nitroglycerin is not a cholesterol-lowering agent, but a vasodilator that relaxes the blood vessels and improves blood flow.It has no effect on fat-soluble vitamin absorption.
Choice D is wrong because beta blockers are not cholesterol-lowering agents, but drugs that lower blood pressure and heart rate by blocking the effects of adrenaline.They have no effect on fat-soluble vitamin absorption.
Correct Answer is ["A","B"]
Explanation
Pentoxifylline is a medication that improves blood flow and oxygen delivery to the tissues in patients with peripheral vascular disease (PVD), a condition that causes narrowing of the arteries in the legs.Pentoxifylline can help reduce the symptoms of intermittent claudication, which is cramping pain in the legs that occurs with walking and improves with rest.
Choice A is correct because smoking is a major risk factor for PVD and quitting smoking can improve blood flow and prevent further damage to the arteries.
Choice B is correct because prolonged sitting or standing can reduce blood flow to the legs and worsen symptoms of PVD.
Patients should avoid crossing their legs, wearing tight clothing, or exposing their legs to cold temperatures.They should also elevate their legs when resting and move them frequently.
Choice C is wrong because pentoxifylline should be taken on an empty stomach, at least one hour before or two hours after meals, to increase its absorption and effectiveness.
Choice D is wrong because physical activity is beneficial for patients with PVD and intermittent claudication.
Exercise can improve blood circulation, increase muscle strength, reduce pain, and lower cardiovascular risk factors.Patients should be encouraged to walk regularly, as tolerated, and follow a supervised exercise program if available.
