sterilised since the last confirmed negative result; take the unit out of service.”},{“front”:”What is the correct instrument processing sequence?”,”back”:”Transport (closed container) → precleaning → packaging → sterilisation → storage.”},{“front”:”Why is ultrasonic/washer-disinfector precleaning preferred over hand-scrubbing?”,”back”:”Improves operator safety and more consistent debris removal.”},{“front”:”What does ‘standard precautions’ assume about every patient?”,”back”:”Blood and body fluids are treated as potentially infectious, regardless of known diagnosis.”},{“front”:”Why do PPE donning and doffing sequences differ?”,”back”:”Donning goes least-to-most contaminated; doffing minimizes self-contamination risk.”},{“front”:”What is the minimum recommended frequency for biological indicator testing?”,”back”:”Typically weekly at minimum (confirm current local requirement).”},{“front”:”What is the single most effective, lowest-cost infection control measure?”,”back”:”Hand hygiene.”},{“front”:”Why can overpacking a sterilizer load cause failure?”,”back”:”It prevents adequate steam/agent penetration to all surfaces.”}],”quiz”:[{“q”:”The three layers of sterilisation monitoring are:”,”options”:[“Visual, tactile, olfactory”,”Mechanical, chemical, biological”,”Manual, automatic, digital”,”Daily, weekly, monthly”],”answer”:1,”exp”:”These are the three standard monitoring layers.”},{“q”:”A biological indicator specifically confirms:”,”options”:[“Correct cycle time only”,”Actual microbial spore kill”,”Package integrity only”,”Water temperature”],”answer”:1,”exp”:”Biological indicators confirm true sterilisation efficacy.”},{“q”:”A failed biological indicator requires:”,”options”:[“No action if chemical indicators looked normal”,”Recalling all items since the last confirmed negative result”,”Only documenting the failure”,”Continuing to use the sterilizer”],”answer”:1,”exp”:”Recall and reprocessing is required.”},{“q”:”The correct instrument processing sequence begins with:”,”options”:[“Sterilisation”,”Transport in a closed container”,”Storage”,”Packaging”],”answer”:1,”exp”:”Transport comes first in the sequence.”},{“q”:”Precleaning is best performed using:”,”options”:[“Hand-scrubbing exclusively”,”Ultrasonic cleaner or washer-disinfector”,”No precleaning needed”,”Only water rinse”],”answer”:1,”exp”:”Ultrasonic/washer-disinfector is preferred for safety and consistency.”},{“q”:”Standard precautions apply to:”,”options”:[“Only patients with known infections”,”Every patient regardless of diagnosis”,”Only emergency patients”,”Only paediatric patients”],”answer”:1,”exp”:”Standard precautions apply universally.”},{“q”:”PPE donning sequence generally proceeds:”,”options”:[“Most to least contaminated”,”Least to most contaminated”,”Randomly”,”Gloves first always”],”answer”:1,”exp”:”Donning proceeds least to most contaminated.”},{“q”:”Minimum biological indicator testing frequency is typically:”,”options”:[“Annually”,”Weekly at minimum”,”Never required”,”Only after failures”],”answer”:1,”exp”:”Weekly at minimum is standard (confirm locally).”},{“q”:”The most effective, lowest-cost infection control measure is:”,”options”:[“Hand hygiene”,”Expensive equipment”,”Antibiotics”,”Air filtration alone”],”answer”:0,”exp”:”Hand hygiene remains the top infection control measure.”},{“q”:”Overpacking a sterilizer load risks:”,”options”:[“Faster cycles”,”Inadequate steam/agent penetration”,”Better sterilisation”,”No effect on outcome”],”answer”:1,”exp”:”Overpacking can prevent adequate penetration.”},{“q”:”A chemical indicator confirms:”,”options”:[“Actual spore kill”,”Exposure to sterilising conditions (colour change)”,”Nothing useful”,”Water quality”],”answer”:1,”exp”:”Chemical indicators confirm exposure, not kill.”},{“q”:”A mechanical indicator records:”,”options”:[“Colour change on a strip”,”Cycle time, temperature, and pressure from the sterilizer itself”,”Spore viability”,”Operator handwriting”],”answer”:1,”exp”:”Mechanical indicators are the sterilizer’s own recorded parameters.”},{“q”:”Why might normal mechanical/chemical indicators still accompany a failed biological indicator?”,”options”:[“This combination is impossible”,”A packing/loading error can block penetration despite correct machine performance”,”Chemical indicators are unreliable always”,”Biological indicators are inaccurate”],”answer”:1,”exp”:”Machine performance normal doesn’t guarantee adequate penetration to every item.”},{“q”:”A percutaneous sharps injury should be managed by:”,”options”:[“Ignoring it if minor”,”Washing, following office protocol, and seeking medical evaluation”,”Continuing treatment without pause”,”Waiting until end of day to report”],”answer”:1,”exp”:”Immediate washing and protocol-driven response is correct.”},{“q”:”Waterline maintenance testing helps ensure:”,”options”:[“Adequate water pressure only”,”Water quality meets infection control standards”,”Faster patient turnover”,”No relevance to infection control”],”answer”:1,”exp”:”Waterline testing protects water quality standards.”},{“q”:”PPE doffing sequence is designed to:”,”options”:[“Maximize contamination risk”,”Minimize self-contamination during removal”,”Match the donning order exactly”,”Skip glove removal”],”answer”:1,”exp”:”Doffing order minimizes self-contamination.”},{“q”:”High-touch clinical contact surfaces should be:”,”options”:[“Ignored between patients”,”Barriered or disinfected between patients”,”Cleaned only once daily”,”Left untouched by protocol”],”answer”:1,”exp”:”High-touch surfaces need between-patient attention.”},{“q”:”The rationale for treating every patient under standard precautions is:”,”options”:[“Known infection status is always disclosed accurately”,”Infection status may be unknown or undisclosed”,”It is legally required only for high-risk patients”,”It reduces cost only”],”answer”:1,”exp”:”Standard precautions account for unknown/undisclosed status.”},{“q”:”Sterilisation packaging should include:”,”options”:[“No indicator needed”,”A chemical indicator strip”,”Only a label with date”,”Nothing beyond the instrument”],”answer”:1,”exp”:”Chemical indicators are included in each package.”},{“q”:”The overall goal of the three-layer monitoring system is to:”,”options”:[“Answer different questions about cycle effectiveness comprehensively”,”Duplicate the same check three times”,”Save time”,”Replace documentation”],”answer”:0,”exp”:”Each layer answers a distinct question about efficacy.”}]};
