Lessons 1 to 4. No account needed.
Sterile processing is not washing and wrapping. Devices move one way around a cycle, and every step guards the patient.
About 16 min · 2 short reads · 18 questions
Medical words are not random. They are built from parts, such as a prefix, a root and a suffix, that you can read.
About 16 min · 2 short reads · 16 questions
A procedure name is more than a label. Its ending says what the surgeon will do, and its front often says how.
About 16 min · 2 short reads · 18 questions
The body is not a list of parts to memorize. Cells build tissues, tissues build organs, and organs work as systems.

An anterior hip replacement is not a posterior one. Direction words can change the instruments.
About 16 min · 2 short reads · 18 questions
Microbes are not all alike: spores are very hard to kill, and prions resist standard sterilization.
About 16 min · 2 short reads · 18 questions
Looking clean proves nothing. Asepsis, hand hygiene and the dress code protect what you cannot see.
About 16 min · 2 short reads · 18 questions
Infection does not need a visibly sick person. It needs six links, and your daily habits can break them.
About 16 min · 2 short reads · 13 questions
A standard is usually not law, but surveyors may still cite it, and the strictest regulation always applies.
About 16 min · 2 short reads · 19 questions
Decontamination does not start in decontamination. It starts where the instrument was used, before the soil dries.
About 16 min · 2 short reads · 18 questions
Clean means every bit of soil is gone, seen and unseen. A shiny instrument or a finished cycle does not prove it.
About 17 min · 2 short reads · 14 questions
Water alone cleans poorly, and a detergent kills microorganisms only if it contains a biocide.
About 16 min · 2 short reads · 18 questions
High-level disinfection is not sterilization, and a disinfectant works only where it stays wet for the full time.
About 16 min · 2 short reads · 13 questions
Soil weakens every disinfectant, and a high-level solution can fail its strength test before its reuse life ends.
About 16 min · 2 short reads · 17 questions
Two instruments that look alike can do different jobs, and stainless steel can still stain and rust.
About 16 min · 2 short reads · 19 questions
An instrument can look clean and still hide soil in a joint, have dull tips or be harmed by the wrong chemical.
About 17 min · 2 short reads · 18 questions
A powered handpiece never goes under liquid unless its IFU allows it, and sound-looking insulation can hide tiny holes.
About 16 min · 2 short reads · 18 questions
A clean look is no proof for a flexible endoscope. Test it, dry it with air, not alcohol, and label it.
About 17 min · 2 short reads · 19 questions
Assembly is more than filling a tray. Each item must work, match the count sheet and sit where the sterilant reaches it.
About 17 min · 2 short reads · 14 questions
A pack is not just a cover. It must let the sterilant in, keep microbes out and open cleanly when it is used.
About 17 min · 2 short reads · 19 questions
Lessons 21 to 52. Part of Full Access.
Immediate use steam sterilization is no shortcut: every normal step still happens, and the item goes straight to use.
About 16 min · 2 short reads · 13 questions
Hot is not enough. Steam must touch every surface, for long enough, and carry its moisture with it.
About 16 min · 2 short reads · 11 questions
The cycle ending is not the end: read the record, cool the load untouched, and treat a wet pack as contaminated.
About 16 min · 2 short reads · 13 questions
Low temperature is not one method: EO needs a long aeration, gas plasma needs none, and VHP aerates in the chamber.
About 16 min · 2 short reads · 16 questions
Low-temperature methods are not interchangeable. The device, its pack and the load must all suit the method.
About 15 min · 2 short reads · 18 questions
A wrapper is a barrier, not a wall: a pack stays sterile only until an event, such as moisture or damage, ends it.
About 16 min · 2 short reads · 18 questions
A negative spore test does not prove every item is sterile. It shows the cycle met the conditions that sterilize.
About 16 min · 2 short reads · 18 questions
An incomplete record is as harmful as none. A recall relies on load records to find the packs.
About 16 min · 2 short reads · 13 questions
Ninety-nine perfect sets do not make a quality department. The customer remembers the one with a missing instrument.
About 16 min · 2 short reads · 18 questions
FMEA looks ahead for what could fail. Root cause analysis looks back at what did. They are not the same tool.
About 16 min · 2 short reads · 17 questions
Supply Chain usually buys the stock, but you keep what you handle in date, intact and in its place, and report problems.
About 16 min · 2 short reads · 18 questions
Used equipment that looks clean still counts as contaminated. You clean and check it; Biomed tests and repairs it.
About 16 min · 2 short reads · 18 questions
Tracking systems work only when people use them faithfully, and they need a back-up plan for the day they go down.
About 16 min · 2 short reads · 18 questions
Thinking an injury will never happen to you is not safety. It is a false sense of security.
About 16 min · 2 short reads · 18 questions
No smell does not mean no exposure. Monitors can detect chemicals far below what your nose can.
About 16 min · 2 short reads · 19 questions
Being heard is not being understood. "It's in the sterilizer" still leaves surgery guessing how long.
About 16 min · 2 short reads · 18 questions
Technical skill is not enough on its own. Success also turns on how well you get along with people.
About 16 min · 2 short reads · 18 questions
Development is not only for people chasing a promotion. Every technician has to keep current.
About 16 min · 2 short reads · 13 questions
A color change is not proof of sterility.
About 17 min · 2 short reads · 19 questions
The room rules are not trivia. Each one keeps contamination from moving toward clean items.
About 16 min · 2 short reads · 17 questions
The trip is part of the process. It can undo a sterile pack or injure the person who carries a soiled tray.
About 16 min · 2 short reads · 18 questions
Privacy rules are not only for the bedside. A pick list with a patient's name on it is protected too.
About 16 min · 2 short reads · 18 questions
Class I is the most serious recall, and an item from a recalled lot is recalled even when it looks perfect.
About 16 min · 2 short reads · 19 questions
"It powers on" is not a safety check. The cord and plug need a look first.
About 16 min · 2 short reads · 18 questions
Antiseptic and disinfectant are not two words for one thing, and nothing is partially sterile.
About 16 min · 2 short reads · 17 questions
A device report does not wait for proof, and user error still counts.
About 16 min · 2 short reads · 18 questions
A catalog number etched on an instrument is not its UDI.
About 16 min · 2 short reads · 18 questions
Storage safety is not only about sterility. It also protects the people who stack the shelves and push the carts.
About 16 min · 2 short reads · 17 questions
Cleaning up well does not make a used single-use device reusable. Its labeling decides, not its looks.
About 16 min · 2 short reads · 18 questions
An empty gas cylinder still stands upright and chained, and a cylinder's color is not its label.
About 16 min · 2 short reads · 18 questions
Workplace violence is not only a physical attack. A threat, verbal abuse or a coworker's bullying counts too.
About 16 min · 2 short reads · 18 questions
Cleared for steam does not mean cleared for every steam cycle. Match the wrap, pouch and indicators to the cycle.
