What is the maximum allowable level of chloramine in dialysis water according to AAMI standards?
Answer: 0.1 mg/L
AAMI standards require chloramine levels in dialysis water to be below 0.1 mg/L to prevent hemolytic anemia.
Which water treatment component is primarily responsible for removing chlorine and chloramines from dialysis water?
Answer: Activated carbon tank
Activated carbon tanks adsorb chlorine and chloramines from the water supply before it reaches the reverse osmosis unit.
How often should total chlorine be tested in the water treatment system during a dialysis treatment day?
Answer: At the beginning of each treatment day
Total chlorine must be tested at the beginning of each treatment day to ensure patient safety before dialysis begins.
What is the purpose of the softener in a dialysis water treatment system?
Answer: Removes calcium and magnesium ions
The water softener uses ion exchange to remove calcium and magnesium ions that would otherwise foul the reverse osmosis membrane.
Which of the following contaminants in dialysis water can cause aluminum toxicity in patients?
Answer: Aluminum
Aluminum in dialysis water can accumulate in patients causing dialysis encephalopathy, osteomalacia, and anemia.
The reverse osmosis (RO) unit in water treatment works primarily by:
Answer: Forcing water through a semi-permeable membrane under pressure
Reverse osmosis forces water under pressure through a semi-permeable membrane, rejecting dissolved contaminants and producing purified water.
