A patient with peripheral vascular disease has been on pentoxifylline (Trental) for 2 weeks.
Which statements by the patient indicate no need for further patient teaching about the disease? Select all that apply.
"I should quit smoking to improve blood flow.".
"I need to avoid prolonged sitting or standing.".
"I should take my pentoxifylline with meals.".
"I need to limit my physical activity to avoid worsening symptoms.".
Correct Answer : A,B
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.

Correct Answer is D
Explanation
Anticoagulant drugs are medicines that prevent blood clots from forming or growing larger.
They do not dissolve existing clots or transport platelets. They work by interfering with different steps of the blood coagulation pathway, which is the process that leads to clot formation.
Choice A is wrong because anticoagulant drugs do not dissolve existing clots.
To dissolve clots, you need fibrinolytic drugs, which break down the fibrin mesh that holds the clots together.
Choice B is wrong because anticoagulant drugs do not transport platelets.
Platelets are blood cells that stick together to form clots.
Anticoagulant drugs may affect the function of platelets, but they do not move them around.
Choice C is wrong because anticoagulant drugs do not act as fibrinolytic agents.
Fibrinolytic agents are drugs that activate plasmin, an enzyme that breaks down fibrin.
Anticoagulant drugs may inhibit the formation of fibrin, but they do not break it down.
Some examples of anticoagulant drugs are warfarin, heparin, and factor Xa inhibitors.
The normal ranges for some blood tests that measure the effects of anticoagulants are:
• Prothrombin time (PT): 11 to 13.5 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
