How long does the sample valve need to be flushed after the RO has been
running for 15 minutes before a sample is collected? Correct Ans - 2
minutes
What is the frequency for testing the Total Chlorine? Correct Ans -
Before the first patient of the day is put on AND every 4 hours after that.
Name the test trip used to test Total Chlorine: Correct Ans - RPC
Ultra-Low Total Chlorine Strips
What does TDS stand for? Correct Ans - Total Dissolved Solids
The RPC Ultra-Low Total Chlorine Strips are used to test the functionality of
what tanks in the water room? Correct Ans - GAC (Granular Activated
Carbon) tanks
Which tanks in the water room are responsible for removing Total Chlorine?
Correct Ans - GAC tanks (Granular Activated Carbon tanks)
What is the TDS meter used to measure? Correct Ans - The TDS meter
measures the functionality of the RO and how well it is removing those
particles we do not want to expose the patient to during treatment.
What 3 things does the pHoenix Meter, pHoenix XL Meter and Myron L-D6
Meter test dialysate for? Correct Ans - 1. conductivity
2. pH
,3. temperature
What strips are used to measure water hardness? Correct Ans -
SteriChek Water Hardness Reagent Strips
What do the SteriChek Water Hardness Reagent Strips measure for?
Correct Ans - water hardness
SteriChek Water Hardness Reagent Strips measure water hardness. What two
minerals do these strips specifically measure that are responsible for hard
water? Correct Ans - calcium and magnesium
The water system uses a water softener to remove calcium and magnesium.
When calcium and magnesium are removed, what is added to the water in
their place? Correct Ans - sodium (Na+)
How often is water hardness tested? Correct Ans - 2 times a day
When is water hardness (caused by calcium and magnesium) tested?
Correct Ans - Before the first patient and at the end of the day
When the water is tested for water hardness (caused by calcium and
magnesium) before the first patient is put on AND at the end of the day (twice
daily), what is the acceptable amount of these minerals found with the
SteriChek Water Hardness Reagent Strips? Correct Ans - < 20 ppm
(parts per million)
What test strips are used to measure residual chlorine? Correct Ans -
Water Check RC Strips
When do we use the Water Check RC Strips during the week? Correct Ans
- after bleach day and before the first patient is put on
If you find a vile of test strips that are not dated, can we use them for testing
purposes? Correct Ans - no
What is the minimum number for GAC (carbon tanks) your clinic can have?

, ***Your clinic may have 4 GAC tanks
In a clinic with 2 GAC tanks, the first tank is called the ______ tank, and the
second tank is called the ______ tank. Correct Ans - worker, polisher
The worker tank is also called the _______ tank. Correct Ans - primary
The polisher tank is also called the _______ tank. Correct Ans -
secondary
When the opener at your clinic runs the RO for 15 minutes then waits the
required 2 minutes for the sample valve to run before collecting a sample,
after which GAC tank is the valve located for testing Total Chlorine?
Correct Ans - worker tank (primary tank)
***We are checking the functionality of the worker tank
How many employees have to watch the sample for the Total Chlorine test be
obtained? Correct Ans - 2 (opener plus a second employee)
***One employee MUST be a RN
Two employees (the opener plus a second employee) must be present when
the sample for the Total Chlorine test is obtained. How many employees total
must be present when the test strip is gently moved back and forth in the
sample cup? Correct Ans - 2
How many times must the sample cup for testing Total Chlorine be rinsed
before obtaining the sample? Correct Ans - 3
***Just like the Myron Meter
How long does the test strip for Total Chlorine need to be moved back and
forth in the water? Correct Ans - 60 seconds.
After the test strip for Total Chlorine is moved back and forth in the water for
60 seconds, how long do the two employees have to wait BEFORE reading the
results on the strip? Correct Ans - 20 seconds
