CETa LATEST 2026 EXAM MANUAL QUESTIONS AND
ANSWERS GRADED A+
✔✔How do you calculate air changes? (ACHPH) - ✔✔-total room CFM/Room Volume
Ft3 X 60 to convert minutes to per hour.
✔✔what might you need to consider when accommodating a canopy connected BSC? -
✔✔-Ceiling height should be higher, 9 1/2 Ft Tall
-higher ceiling to accommodate balancing damper
✔✔Does USP 797 require interlocking doors on passthroughs ? - ✔✔-No they do not,
but it is highly recommended
✔✔what is a main difference between "Vented Pass through" and a "Recirculating Pass
through" - ✔✔-vented pass throughs intake air upstream of the fan and push air through
the HEPA filter then work chamber.
-recirculating pass throughs are found between negative pressure buffer rooms
typically. They only run for around 1 min during there "Purge Cycle"
✔✔What is the Recommended temperature range for compounding pharmacies? - ✔✔-
they're supposed to range between 64-68F
-USP 797 Recommends Temps below 68F/20C
✔✔What is the Recommended humidity range for compounding pharmacies? - ✔✔-
cleanrooms values typically between 30%-60% relative humidity.
-USP 797 recommends no more than 60% RH
✔✔How often must a compounding area be certified ? - ✔✔-initially and every 6 months
✔✔What is a designated persons? - ✔✔-person responsible and accountable for the
performance and operation of the compounding facility.
✔✔How Are Air Change Calculated ? (Not Equation) - ✔✔-In a positive pressure state
room it is calculated by overall supply volume.
-In a negative pressure state room it is calculated by overall exhausted air (Returns,
PEC)
✔✔what is the accuracy of a capture hood? - ✔✔-accuracy of +/-3% of reading +/-7
CFM
✔✔what is the accuracy of a thermal anemometer? - ✔✔-accuracy of -/+3% or -
/+3FPM, whichever is greater.
, ✔✔what is the accuracy of a velgrid/manometer? - ✔✔-accuracy of -/+3% of reading
and -/+7 FPM .

a plane 6-12 inches from filter face.
-using proper stand offs
-grid spacing no larger than 12 inches.
-starting 6 inches from inner edge of filter, 6 inches from filter media.
✔✔for rooms larger than 1000m2 how do you calculate # of particle count locations? -
✔✔27* Area/1000= number of locations
✔✔What consists of USP Chapter 797? - ✔✔-Pharmaceutical compounding
-sterile preparations

✔✔What consists of USP 825? - ✔✔-Radio pharmaceuticals
-Preparation, compounding, dispensing and re packing.
✔✔ Compounding Aseptic Containment Isolator (CACI) - ✔✔-Used for Compounding
HD Drugs.
-Class 1 CSP's may be placed in a SCA.
-Class 2 CSP's cleanroom with ISO 7 Buffer Room.
✔✔Compounding Aseptic Isolator (CAI) - ✔✔- Used for Compounding Sterile Non-HD
Drugs.
-Class 1 CSP's may be placed in a SCA.
-Class 2 CSP's cleanroom with ISO 7 Buffer Room.
✔✔Laminar Airflow Workbench (LAFW) - ✔✔- Limited to Non-Sterile preparation.
-ISO 5 Horizontal/Vertical Unidirectional Air.
✔✔Vertical Laminar Flow Zone - ✔✔- Uses ceiling mounted HEPA's.
- Unidirectional airflow over stainless steel tables.
✔✔Biosafety Cabinet (BSC) - ✔✔-NIOSH Alert recommends No air recirculated for HD
Preparation.
