STUDY: PATIENT CKD Gary is 49 years old and has chronic kidney disease. He is an active man who works at a large manufacturing plant. Recently, he has begun to tire more easily and has little appetite. He has lost 5% of his normal body weight and has noticed ankle swelling and blood in his urine. After a complete workup, the physician's findings included the following: no prior illness except a case of the flu with a throat infection during his overseas service in the Army, presence of albumin, red blood cells, and white blood cells in the urine, high blood potassium, phosphorus, creatinine, and urea levels, and severely decreased glomerular filtration rate of 20 mL/min per 1.73 m². Other symptoms include hypertension, edema in the lower legs, headache, occasional blurry vision, and low-grade fever. The physician discussed the findings and the serious prognosis of stage chronic kidney disease with Gary and his wife. Together with the dietitian, they explored his immediate and ultimate needs. They also discussed the need for medical management, including prescribed medications, dialysis, or renal transplantation. Gary and his wife weighed the options and decided to pursue medical management. Over the next 10 months, Gary's symptoms worsened. He had increased nausea, joint pain, bone discomfort, and occasional blurry vision.
