Need help with Anatomy and Physiology Case Study (Urinary Physiology)

Need help with Anatomy and Physiology Case Study (Urinary Physiology)?
Urinary Physiology A 26-year-old with diabetes mellitus has developed renal failure. While waiting for a kidney transplant, he is on maintenance hemodialysis eight to ten hours three times each week. He is on a diet restricted in sodium (500 mg/day), potassium (2.6 g/day), and protein as well as his usual diabetic diet. He has a shunt in his right wrist to allow for easy hookup to the dialysis machine. Prior to hemodialysis, his representative blood values are the following: Serum sodium 120 mEq/L Serum potassium 6.4 mEq/L Serum chloride 102 mEq/L Serum creatinine 16 mg/dL Hematocrit 24% The dialysis fluid in the kidney dialysis machine contains the following: Sodium 134 mEq/L Potassium 2.6 mEq/L Calcium 2.5 mEq/L Magnesium 1.5 mEq/L Chloride 104 mEq/L Sodium acetate 36.6 mEq/L Anhydrous dextrose 2 g/L Questions: 1. What is hemodialysis? 2. Following eight to ten hours of hemodialysis, do you think the following blood values would be increased, decreased, or remain the same? Explain your reasoning. Serum sodium Serum potassium Serum chloride Serum creatinine Hematocrit 3. Why does anemia usually develop with maintenance dialysis? 4. Why is hemodialysis required every two to three days for eight to ten hours/day for individuals with complete renal failure? (Flow rate of blood through the dialyzer is 150-300 mL/min.) 5. Differentiate between hemodialysis and peritoneal dialysis
