Which components are included in the composition of the SDS?

The composition of the SDS, or system delivery system, includes various components crucial for the efficient and safe operation of dialysis. The correct choice highlights the bicarb mix tank and acid storage tank, which are essential for preparing the dialysate. The bicarb mix tank is responsible for mixing bicarbonate with purified water to create dialysate that helps maintain the patient's acid-base balance during treatment. The acid storage tank holds the acidic component necessary for the proper formulation of the dialysate.

In contrast, while options may include relevant equipment related to dialysis or the management of the patient or waste, they do not represent the essential parts of the SDS that directly contribute to the preparation of dialysate. The other choices involve components that might play supportive roles in the broader dialysis process but are not specific to the primary functions of the SDS. Recognizing the specific roles of the bicarb mix tank and acid storage tank within the SDS framework is important for understanding the management of dialysate and overall dialysis performance.
