#1
What is the primary goal of water treatment in healthcare settings?
To reduce microbial contamination
ExplanationTo eliminate harmful microorganisms from water.
#2
In water treatment, what does the term 'flocculation' refer to?
Clumping together of particles for easier removal
ExplanationFlocculation aids in the aggregation of particles for efficient filtration.
#3
What is the purpose of a sediment filter in healthcare water treatment?
Removes suspended particles and debris
ExplanationSediment filters strain out solid particles to improve water quality.
#4
Which water treatment method is commonly used for removing chlorine and improving taste in healthcare facilities?
Activated carbon filtration
ExplanationActivated carbon effectively absorbs chlorine and enhances water flavor.
#5
What is the purpose of a demineralization system in healthcare water treatment?
Removes minerals like calcium and magnesium
ExplanationDemineralization systems eliminate minerals to prevent scaling and corrosion.
#6
Which of the following is a common method for disinfecting water in healthcare facilities?
Boiling
ExplanationBoiling water effectively kills most pathogens.
#7
What is the acceptable pH range for water used in healthcare facilities?
6-8
ExplanationMaintaining a neutral pH is crucial for compatibility with medical equipment and safety for consumption.
#8
Which regulatory agency often establishes guidelines for water quality in healthcare settings?
Centers for Disease Control and Prevention (CDC)
ExplanationCDC provides standards to ensure safe water practices in healthcare.
#9
What is the purpose of a water softener in healthcare water treatment?
Removes minerals like calcium and magnesium
ExplanationWater softeners prevent mineral buildup in pipes and equipment.
#10
What role does activated carbon play in water treatment for healthcare facilities?
Removes contaminants through absorption
ExplanationActivated carbon traps impurities through adsorption.
#11
Which waterborne pathogen poses a significant risk in healthcare water systems?
Legionella bacteria
ExplanationLegionella bacteria can cause severe respiratory infections.
#12
What role does reverse osmosis play in water treatment for healthcare facilities?
Removes contaminants through a semi-permeable membrane
ExplanationReverse osmosis filters out impurities by forcing water through a selectively permeable membrane.
#13
Which chemical is commonly used for disinfection in water treatment processes for healthcare facilities?
Bleach (sodium hypochlorite)
ExplanationBleach is a potent disinfectant effective against a wide range of pathogens.
#14
What is the significance of Legionella risk assessments in healthcare water systems?
Identifying potential sources of Legionella bacteria
ExplanationAssessments help locate and mitigate risks associated with Legionella contamination.
#15
What is the purpose of a UV disinfection system in healthcare water treatment?
Destroys microorganisms by ultraviolet light exposure
ExplanationUV light effectively kills microorganisms by damaging their DNA.
