The statement that dialysis effectively removes water-soluble vitamins is accurate. During the dialysis process, substances present in the blood, including water-soluble vitamins such as vitamin C and B-complex vitamins, can pass through the dialysis membrane, leading to their removal from the bloodstream. This is particularly important for patients undergoing regular dialysis, as they may experience deficiencies in these vitamins due to their loss during treatment.

Understanding the mechanism of dialysis is crucial; it works on the principle of diffusion, where smaller molecules like water-soluble vitamins can diffuse across the dialysis membrane. This process emphasizes the importance of monitoring nutritional status and considering supplementation of water-soluble vitamins for patients receiving dialysis, given that they may need these vitamins replaced more frequently to prevent deficiencies.

In contrast, the other statements misrepresent the interaction between dialysis and water-soluble vitamins. The idea that dialysis does not remove them overlooks the fundamental principle of solute removal, while suggesting that only certain vitamins are removed or that dialysis increases absorption contradicts established outcomes observed in dialysis patients. This understanding is key in renal nutrition management for those undergoing dialysis.
