What effect do clotted dialyzer fibers have on treatment adequacy?

Clotted dialyzer fibers significantly impact treatment adequacy because they reduce or eliminate fiber permeability. Dialyzers function by allowing waste products and excess fluids to pass through their semi-permeable membranes while retaining larger blood cells and proteins. When these fibers become clotted, their ability to facilitate the exchange of solutes and fluids is compromised. This means that the blood is not effectively cleaned or filtered, leading to inadequate dialysis treatment. Thus, this diminishes the patient's overall treatment effectiveness, as the primary goal of dialysis is to remove toxins and maintain fluid balance.

The other options imply that clotted fibers could enhance or have no impact on treatment, which contradicts the fundamental role of the dialyzer in ensuring proper filtration and treatment effectiveness.
