Worked examples: how to reason through CSPT questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: A CSP labeled 'Protect from Light' must be stored in which of the following?

1. Clear glass vial in a standard cabinet
2. Amber vial or light-resistant packaging
3. Open stainless steel tray under fluorescent lighting
4. Refrigerator with transparent door

Answer: B. Amber vial or light-resistant packaging

Explanation:

The correct answer is amber vial or light-resistant packaging. A 'Protect from Light' label means the preparation can break down when exposed to light, so the container has to block it. Amber glass and opaque packaging do that.

A clear glass vial in a cabinet gives no protection once the door opens, and the cabinet does not change what the vial itself lets through. An open steel tray under fluorescent lighting is the worst option: the contents are exposed to light and to the room. A refrigerator with a transparent door controls temperature, not light.

The rule to remember: match the storage to every instruction on the label. A light warning needs light-blocking packaging, and a temperature warning needs temperature control. These are separate requirements, and one does not stand in for the other.

Example 2

Question: What action should be taken if the primary engineering control (PEC) HEPA filter fails certification during routine testing?

1. Immediately cease compounding until the filter is repaired or replaced
2. Continue compounding using extra PPE as a precaution
3. Notify the pharmacist but continue low-risk compounding only
4. Reduce airflow speed to prevent further damage

Answer: A. Immediately cease compounding until the filter is repaired or replaced

Explanation:

The correct answer is to stop compounding right away until the filter is repaired or replaced. The HEPA filter is what keeps the work zone clean, and a failed certification means nobody can show that the air quality is still adequate. Without that, sterility cannot be assured.

Extra PPE does not replace clean air, so continuing with it is wrong. Telling the pharmacist is sensible, but carrying on with low-risk work still uses a compromised hood. Reducing airflow speed is not an approved fix and may make air control worse, not better.

The rule to remember: when a primary engineering control fails certification, it is out of service. Work stops, the problem is reported, and compounding resumes only after the equipment is corrected and passes testing again.

Example 3

Question: When compounding a hazardous drug, a technician accidentally spills a small amount on the C-PEC work surface. What is the correct immediate action?

1. Continue working and clean up after the batch is complete
2. Remove all items, don a second pair of gloves, and use the HD spill kit
3. Notify the pharmacist and leave the area immediately
4. Wipe the spill with a standard alcohol wipe and resume compounding

Answer: B. Remove all items, don a second pair of gloves, and use the HD spill kit

Explanation:

The correct answer is to remove the items, put on a second pair of gloves, and use the hazardous drug spill kit. A spill inside the work area is contained there, and the aim is to clean it without spreading it to other surfaces, to the preparation, or to you.

Continuing to work and cleaning later lets contamination spread and exposes you for longer. Telling the pharmacist and leaving the area immediately walks away from a spill that is still open and unmanaged. A standard alcohol wipe does not deactivate or remove hazardous drug residue and can smear it.

The rule to remember: for a hazardous drug spill, stop, protect yourself with added PPE, and use the designated kit, following your facility's spill procedure.

How to use these practice tests

PTCB has not published a content outline that we could verify for this page, so start with the official CSPT page on ptcb.org and read its exam outline and candidate guidance. Write down each topic area it names and any pathway rules you still need to meet.

Then use our practice sets in short, focused sessions. Begin with a set from your weakest area, such as hazardous drug compounding or sterile compounding calculations. After each answer, read the explanation even when you were right, and note the rule behind it. If you miss a question, write a short note on why the correct option works and why yours did not.

Return to missed topics in a later session rather than repeating the same set straight away. Mix in the quality assurance, aseptic technique, and storage sets so you are not studying topics in isolation. Calculations need hands-on repetition, so work them on paper and check your units.

Our questions are written by us and are not real exam questions. Use them to find gaps, then close those gaps with your facility's procedures and the official USP material. Schedule the exam inside your authorization window and keep the retake rules in mind when you choose a date.

Free CSPT Practice Test to Prepare for Certification

A CSPT practice test is one of the most effective ways to prepare for the Certified Surgical Processing Technician exam administered by CBSPD. The actual CSPT exam contains 75 multiple-choice questions (60 scored, 15 unscored) covering decontamination, preparation and packaging, sterilization, and sterile storage and distribution. Working through practice questions helps you identify weak areas in your knowledge of instrument processing workflows and sterilization science before sitting for the timed exam.

What Topics Does the CSPT Exam Cover

The CSPT exam is weighted heavily toward decontamination procedures and sterilization methods, with additional sections on quality assurance, anatomy and physiology related to surgical instrumentation, and regulatory standards from AAMI and The Joint Commission. Familiarize yourself with biological indicator testing, the Spaulding classification system, and proper handling of loaner instrument trays, as these are frequently tested areas.

CSPT Practice Exam Questions and Study Strategy

Taking a CSPT practice exam under timed conditions builds the stamina needed for the actual three-hour testing window at a Prometric center. Focus your study sessions on the areas weighted most heavily in the CBSPD exam blueprint, particularly decontamination principles, which account for a significant portion of scored questions. Each practice exam attempt should be followed by a careful review of incorrect answers to reinforce the underlying sterile processing concepts.

How to Use Practice Exams Effectively

Complete each CSPT practice exam without referencing study materials, then review every missed question against current AAMI ST79 and ST77 standards. Track your scores across multiple attempts to confirm consistent improvement, aiming for 70 percent or higher before scheduling your official exam date with CBSPD.

Pros and Cons at a Glance

Sample CSPT - Compounded Sterile Preparation Technician Practice Questions

Try these questions from our free CSPT - Compounded Sterile Preparation Technician practice tests. The correct answer and an explanation follow each question.

1. A pharmacist requests a sterile compounded preparation using a non-sterile excipient as a preservative. What must be verified before use?

   • A. The excipient must have a Certificate of Analysis confirming identity, purity, and sterility grade
   • B. The excipient must be sourced from a local supplier only
   • C. The excipient must be pre-filtered through a 0.45 µm filter by the compounder
   • D. The excipient must be approved by the FDA as a new drug

Answer: A. The excipient must have a Certificate of Analysis confirming identity, purity, and sterility grade

All non-sterile ingredients used in CSP compounding must have a Certificate of Analysis (CoA) verifying identity, purity, and suitability for sterile preparation.

Answer: D. Ensuring adherence to proper gowning and aseptic techniques

CSPTs are responsible for following proper gowning and aseptic techniques to maintain a sterile cleanroom environment.

Answer: B. Shoe covers, head/beard covers, face mask, hand washing

The proper garbing sequence generally proceeds from the dirtiest to the cleanest activities to prevent contamination. Shoe covers are applied first, followed by head/beard covers and a face mask. After these items are on, thorough hand hygiene is performed before moving to the buffer area to don a gown and sterile gloves.

Answer: D. Sterilization by filtration using a 0.22-micron filter

Heat-labile substances are damaged by high temperatures, making dry heat and steam sterilization (autoclaving) unsuitable. Sterilization by filtration removes microorganisms by passing the solution through a 0.22-micron filter without using heat, thus preserving the integrity of the drug.
