RPC test strips are used to test for which of the following?

RPC test strips are specifically designed to assess levels of chlorine and chloramines in water. These compounds are critical to monitor in water systems, especially for ensuring water quality and safety in dialysate production. Chlorine is a common disinfectant used in water treatment, while chloramines, which are formed by the combination of chlorine with ammonia, can also be present as a secondary disinfectant.

Testing for chlorine and chloramines is vital as both can impact the health of patients undergoing dialysis. Elevated levels of chlorine or chloramines in the water supply used for dialysis can lead to adverse effects on blood cells and potentially harm patients. Therefore, regular testing using RPC test strips ensures that the water quality meets the stringent safety standards necessary for medical use.

The other choices pertain to different aspects of water quality testing, such as nitrates and nitrites (which are typically tested with different methods), alkalinity and hardness, and fluoride, none of which are specifically indicated to be tested using RPC test strips.
