Answer to Question 1
Answer: C
Anemia is common in clients with renal disease. Among the factors causing the anemia are decreased production of erythropoietin by the kidneys and shortened red blood cell (RBC) life. Erythropoietin is involved in the stimulation of the bone marrow to produce RBCs. Metabolic wastes do not suppress the bone marrow. Diet and heredity do not factor into the production of erythropoietin.
Answer to Question 2
Answer: D
Many salt substitutes use potassium chloride. Potassium intake is carefully regulated in clients with renal failure, and the use of salt substitutes will worsen hyperkalemia. Increases in weight do need to be reported to the healthcare provider as a possible indication of fluid volume excess, but this is not the reason why salt substitute is to be avoided. The control of hypertension is essential in the management of a client with kidney disease, but salt substitute is not known to interact with antihypertensive medications. An AV fistula does need to be protected from injury and infection could be caused by constricting clothing, venipunctures, and other items.
