The nurse writes the following nursing diagnosis for a client in acute renal failure—Impaired gas...

(A) Red blood cell production is impaired in renal failure owing to impaired erythropoietin production. This causes a decrease in the delivery of oxygen to the tissue and impairs gas exchange. (B) The conversion of vitamin D to its physiologically active form is impaired in renal failure. (C) In renal failure, a decrease in red blood cell production occurs owing to an impaired production of erythropoietin, leading to impaired gas exchange at the cellular level. (D) The decreased production of renin in renal failure causes an increased production of aldosterone causing sodium and water retention.
