A client taking warfarin after open heart surgery reports pain in both knees. Based on the effects of the medications and the report of pain, bleeding must be suspected as the cause of the pain by the nurse.

Open-heart surgery is any type of surgery in which an incision is made in the chest to operate on the heart muscle, valves, or arteries.

Open-heart surgery may be performed to perform CABG. People with coronary artery disease may need coronary artery bypass graft surgery.

Open-heart surgery is nowadays called traditional heart surgery. Today, many new heart surgeries can be performed with only small incisions rather than wide openings. Therefore, the term "open-heart surgery" is misleading.

Warfarin, sold under brand names such as Coumadin, is a drug used as an anticoagulant.

It is widely used to prevent blood clots such as deep vein thrombosis and pulmonary embolism, and to prevent atrial fibrillation, valvular heart disease, and stroke in people with artificial heart valves.
