Study by domain
Patient Care Equipment and the Spaulding Classification
Five percent of the exam, built almost entirely on one framework that sorts every device by where it goes in the body.
The short answer
Patient Care Equipment and Distribution is 5% of the CRCST exam and rests on the Spaulding classification. Critical items enter sterile tissue or the vascular system and must be sterile. Semicritical items contact mucous membranes or nonintact skin and minimally require high level disinfection. Noncritical items contact intact skin only.

What you need to know
Each point below carries the sentence from the public standard that supports it, with the date it was read. You are not being asked to take our word for any of it.
The Spaulding classification: critical items
Spaulding sorts items by the risk of where they go, not by what they are made of or how dirty they look. Anything entering sterile tissue or the vascular system must be sterile, because any microbial contamination could transmit disease. Surgical instruments, implants, and cardiac and urinary catheters all land here.
Semicritical items
Items contacting mucous membranes or nonintact skin: respiratory therapy and anesthesia equipment, some endoscopes, laryngoscope blades. The guideline explains the tolerance that follows from this: intact mucous membranes generally resist common bacterial spores while remaining susceptible to bacteria, mycobacteria and viruses.
High level disinfection, and the one thing it leaves behind
Complete elimination of all microorganisms except small numbers of bacterial spores. That single exception is the entire boundary between high level disinfection and sterilization, and it is why a critical item cannot be high level disinfected. Spores are the most resistant form of microbial life, which is also why the indicators that verify sterilization are made of them.
Noncritical items
Items contacting intact skin but not mucous membranes: bedpans, blood pressure cuffs, crutches. Intact skin is an effective barrier to most microorganisms, so the sterility of these items is, in the guideline's own phrasing, not critical.
Where noncritical items actually get processed
Most noncritical reusable items may be decontaminated where they are used and do not need to travel to central processing. This is the distribution half of the domain and it is a workflow decision rather than a shortcut: routing every bed rail and blood pressure cuff through the department would swamp it without reducing risk.
Reading is not the same as being ready
Knowing this domain and being able to answer questions on it under a clock are different skills, and the exam tests the second one. The free practice test is scored domain by domain, so it will tell you whether this one is actually costing you points or whether your problem is somewhere else.
