If blood phosphorus levels are elevated, patients may develop
 
  a. anemia.
  b. renal calculi.
  c. osteoporosis.
  d. osteodystrophy.

Question 2

Patients treated with peritoneal dialysis have lower energy needs than those treated with hemodialysis because
 
  a. hemodialysis increases metabolic rate.
  b. peritoneal dialysis suppresses metabolic rate.
  c. dextrose is absorbed from the peritoneal dialysate.
  d. patients treated with peritoneal dialysis are less active.

Answer to Question 1

D
Elevated blood phosphorus levels may lead to osteodystrophy (defective bone development). Anemia in patients with chronic renal disease is caused by failure to produce erythropoietin. Renal calculi are caused by various metabolic imbalances and by poor fluid intake. Osteoporosis is caused by long-term inadequate intakes of calcium and vitamin D and lack of weight-bearing exercise.

Answer to Question 2

C
Patients treated with peritoneal dialysis have lower energy needs than those treated with hemo-dialysis because dextrose is absorbed from the peritoneal dialysate. Hemodialysis does not in-crease metabolic rate and peritoneal dialysis does not suppress metabolic rate. Patients treated with peritoneal dialysis are not less active.
