A client comes to the orthopedic physician's office with a complaint of "water on the knee" the physician has told the LPN in the office to prepare the client for an arthrocentesis. What statement by the nurse is incorrect for patient education of arthrocentesis?

A. "Medication can be infused into the joint during this procedure": Arthrocentesis can be both diagnostic and therapeutic. During the procedure, corticosteroids or other medications may be injected directly into the joint to reduce inflammation and relieve symptoms, so this statement is accurate for patient education. B. "This procedure will relieve the pressure in your knee": Removing excess synovial fluid via arthrocentesis relieves swelling and reduces discomfort caused by increased intra-articular pressure. Explaining this benefit helps the client understand the purpose and expected outcome of the procedure. C. "There is a risk of infection after this procedure": Arthrocentesis involves inserting a needle into the joint, which carries a small risk of introducing pathogens. Informing the patient about potential infection is a necessary part of pre-procedure education for safety and consent purposes. D. "You will need to increase your fluid intake to clear your kidneys of the dye": Arthrocentesis does not involve contrast dye or affect kidney function. Advising increased fluid intake for renal clearance is incorrect and may confuse the patient about the procedure’s purpose.
