Explanation
A. Omeprazole: Not directly nephrotoxic, but long-term use has been associated with interstitial nephritis, although rarely.
B. Ondansetron: Generally safe in renal disease and not known to cause nephrotoxicity.
C. Vancomycin: Known nephrotoxic agent, especially with high trough levels or when used with other nephrotoxins; requires dose adjustment in CKD.
D. Diphenhydramine: Not nephrotoxic; primarily affects the CNS and anticholinergic systems.
Correct Answer is C
Explanation
A. "You have a genetic tendency for the development of anemia.”: Anemia in CKD is primarily due to impaired erythropoietin production, not genetics.
B. "The increased metabolic waste products in your body depress the bone marrow and cause anemia.”: While uremic toxins may have some marrow-suppressive effects, the main cause is lack of erythropoietin.
C. "There is a decreased production by the kidneys of the hormone erythropoietin which is the cause of your anemia.”: In CKD, damaged kidneys produce less erythropoietin, leading to reduced RBC production and anemia.
D. "You are not eating enough iron-rich foods, which is causing anemia.”: Although iron deficiency can contribute, this is not the primary cause in CKD-related anemia.
