Which of the following is NOT a component of the pre-treatment system for hemodialysis?

In hemodialysis, the pre-treatment system is essential for preparing the water used in the dialysate. This system includes various components that ensure the water is purified and free from contaminants.

The carbohydrate infusion mentioned in the choice is not part of the pre-treatment system. The primary focus of the pre-treatment system is to ensure the water quality meets the standards required for safe dialysis. This involves processes such as chemical injection to add specific agents that help with water purification, using a water softener to remove minerals that can cause scaling, and utilizing carbon tanks to filter out chlorine and other harmful contaminants from the water supply.

These functions are critical for protecting both the dialysis equipment and patient health, making them vital components of the pre-treatment system. The infusion of carbohydrates, on the other hand, does not relate to water purification or preparation for hemodialysis. It is more relevant to nutritional management in other contexts, rather than the technical preparations necessary for the dialysis process.
