WATER CCHT EXAM QUESTIONS AND ANSWERS SOLVED
CORRECTLY LATEST UPDATE 2027 GRADED A+
Question 1.
What are the two reason for treating water used for hemodialysis?
Correct Answer: main preventing harm to the patient and preventing damage to
the RO system the
Question 2.
List the contaminants in the water that are living creatures?
Correct Answer: Bacteria and viruses
Question 3.
What are the usual that water becomes contaminated?
Correct Answer: way The process of acid rain, surface water from lakes, ponds,
rivers and reservoris.
Question 4.
Define endotoxin
Correct Answer: A part of the bacterial cell walls that can contaminate water
used for dialysis
Question 5.
What is the function the water softener a water treatment tem? What principle responsible
for this?
Correct Answer: of To remove calcium and magnesium. the water softener works
by ion in exchanges sysis
Question 6.
According to AAMI standard, how often should bacteriological testing of water used for
dialysis be done?
Correct Answer: monthly
Question 7.
Why is water considered safe for drinking not necessarily safe for hemodialysis?
Correct Answer: Patient are exposed to very large volumes of water during
dialysis.
, Question 8.
What contaminants removed by the carbon tants?
Correct Answer: are Chlorine, chloramines, pesticide, industrial solvents, and
some trace organic substances.- The carbon tanks work on the principle of
adsorption( attracts and holds low molecular weight particles from the water,
much like a magnet attracts and holds iron filings)
Question 9.
Exposure to chloramines during hemodialysis may cause?
Correct Answer: Hemolysis
Question 10.
List some examples of the water contaminants?
Correct Answer: Minerals, sodium, chlorine, nitrate salts, pesticides, impurities
from industry, fertilizers, herbicides, fluoride, chloramines( chlorine and
ammonia), trace metals and, Microorganisms.
Question 11.
What sign/symptom most commonly occur from bacteria/endotoxin exposure?
Correct Answer: Fever and chills
Question 12.
Describe the Reverse Osmosis system
Correct Answer: a membrane separation process for removing solutes from a
solution. Feed water is pumped under pressure through the semipermeable
membrane which removes most contaminants from the water. the RO membrane
can reject 95 to 99% of many substances including bacteria viruses, endotoxin,
salts, metals and chemicals
Question 13.
What are water quality checks done on the ter treatment system?
Correct Answer: At the start of the day, before every shift of patient or every 4
hours ( if you wa- do not have set shift)
Question 14.
According to AAMI standards bacteria in dialysis water must not exceed what level?
