The CRCST AI tutor
Got a question wrong and the explanation didn't click? Ask the tutor in plain words. It answers from that question's checked answer key, explanation and cited source, and it isn't allowed to make up numbers.
What it works from on every question
The tutor doesn't search the web or guess at what the CRCST might want. Each time you ask, it's given that one question's material, all reviewed by Andrew Hector Smith (CRCST, CIS, CHL):
- The question and all four choices
Exactly as you saw it.
- The answer key
Our answer for the question. The tutor explains it. It doesn't argue with it or pick a different answer.
- The written explanation
Why the right answer is right, plus why each wrong option is wrong.
- The source it cites
The standard, code or manual the question comes from, by document and section where we can confirm it.
The rules it answers under
- Numbers only from the checked material
If you ask about sterilizer temperatures, exposure times, storage humidity or AAMI section numbers, the tutor only gives a number that's in that question's material. If you ask for one that isn't there, it says it can't confirm it from this question and points you to the source. It's told never to estimate a number or recall one from memory.
- Disagreements go to a person
If you make a strong case that our answer is wrong, the tutor doesn't switch sides. It asks you to press "Report a problem", which sends the question to Andrew Hector Smith for review.
- Only CRCST material
It sticks to the question and the exam. Ask it something unrelated and it steers you back.
- Short, plain answers
Two to six sentences, aimed at the idea behind the question so you can handle the next variation of it, with a memory hook when one helps.
- Names sources, never copies them
It can tell you which document and section to look at, but it won't reproduce copyrighted standards or codes.
What it sees for a real question
This is one of our free Sterile Storage, Transport and Inventory Management questions, with everything the tutor gets when you ask about it.
Question
The PAR level for IV start kits on a medical unit is 24. During the restocking round, a technician counts 9 kits on the shelf. How many kits should be delivered?
- 15
- 9
- 24
- 33
Answer key
A. 15
Explanation
A PAR level is the set quantity that should be on hand. The restock amount is PAR minus what is on the shelf: 24 minus 9 equals 15.
Why the others are wrong
- B: Nine is the number already on the shelf, not the number needed to reach PAR.
- C: Delivering the full PAR would leave 33 kits on the shelf, overstocking the unit.
- D: 33 is the PAR plus the count on hand; it has no meaning for restocking.
Any number the tutor gives you about this question has to come from the text above.
What it can't promise
The tutor runs on an AI model from Anthropic. The material it works from is checked, but the wording of its replies is generated, so it can still phrase something badly or get a detail wrong. The written explanation and its source are always the authority. If a reply looks wrong, use "Report a problem" on the question and we'll look at it. Don't enter personal information or anything about patients.
