CRCST study plan

Map the full decontamination workflow from receiving and sorting through manual cleaning, ultrasonic treatment, and washer-disinfector unloading, and label each step with its purpose

Explain the chain of infection and identify which decontamination failures allow bioburden to survive into assembly

Practice donning and doffing appropriate PPE for the decontamination zone and state the rationale for each item

Differentiate cleaning, disinfection, and sterilization and explain why cleaning must precede both

Identify the correct handling for sharps, contaminated instruments with lumens, and powered equipment during sorting

Compare manual cleaning methods, ultrasonic cleaning, and mechanical washer-disinfectors by indication, monitoring, and limitations

Calculate and verify detergent dilution, water temperature ranges, and exposure times for at least three cleaning scenarios

Describe routine monitoring of automated washers, including verification of cycle parameters and documentation of results

Explain how to inspect cleaned items for residual soil, moisture, and damage before release to assembly

Sequence the response to a failed cleaning verification, including quarantine, reprocessing, and reporting

Inspect at least ten instrument types for cleanliness, function, alignment, and corrosion, and record findings on an inspection checklist

Identify common instrument defects such as cracks, bent tips, loose boxes, and missing screws, and decide repair versus replacement

Assemble instrument sets against a count sheet and verify completeness and correct configuration

Select packaging materials and methods appropriate to the item's weight, size, and sterilization method

Apply package labeling requirements, including contents, sterilizer identification, load, and expiration date

Distinguish rigid containers, peel pouches, and woven or non-woven wraps by barrier properties, compatibility, and shelf-life implications

Explain the principles of steam sterilization and how air removal, pressure, temperature, and time interact

Compare steam, ethylene oxide, hydrogen peroxide, and dry heat with respect to materials, cycle parameters, and aeration requirements

Describe loading patterns that promote steam penetration and identify loading errors that cause failed cycles

Interpret a biological indicator result and state the release criteria for an implant load

Describe the purpose and frequency of physical, chemical, and biological monitoring for each sterilization method

Explain Bowie-Dick testing, its correct placement, and what a pass or fail indicates

Outline the elements of a sterilization record and the documentation needed for load release

Sequence the recall process when a sterilization failure is identified, including notification and investigation steps

Identify common causes of wet packs, air leaks, and cycle aborts, and state the corrective action for each

State the environmental requirements for sterile storage, including traffic control, temperature and humidity, shelving clearance, and location relative to decontamination

Apply event-related shelf-life principles and identify which events compromise package sterility

Explain how to inspect packages before distribution and when to consider an item non-sterile

Describe distribution practices, including rotation, transport, and handling of recalled or expired items

Trace a single instrument set from sterilization through storage to the point of use and identify every point where sterility could be compromised

Summarize the standards and regulatory bodies that govern reprocessing, and distinguish their roles

Identify occupational hazards in the department and match each to a control, including sharps safety, chemical safety, and ergonomics

Outline the elements of a quality assurance program, including documentation, competency assessment, and process improvement

Explain inventory management practices such as par levels, rotation, and tracking of instrument sets

Describe how to report an exposure incident and what documentation is required

Take a timed practice exam across all five domains and score each domain separately

Review every missed question and write a one-line reason for each error, sorted by domain

Re-study the two weakest domains using the notes and deliverables from earlier weeks

Recite the key parameters for each sterilization method and the release criteria for implants from memory

Build a final one-page summary sheet of high-yield facts and verify it against your notes
