The nursing instructor is discussing anemia. The instructor explains about when a person has chronic renal failure; how it leads to a decrease in the production of red blood cells and so the person becomes anemic
This anemia is usually caused by a loss of what? A) Erythropoietin
B) Hydrogen ions
C) Renin
D) Urea
A
Feedback:
When nephrons are lost, as in renal failure, the juxtaglomerular cells that produce erythropoietin are also lost leading to a decrease in red blood cell production and anemia. Urea, renin, and hydrogen do not affect red blood cell production and are not associated with anemia.
