CBSPD FLEXIBLE ENDOSCOPE REPROCESSING
EXAM PREP
Practice Test 2 and Study Guide | 2026/2027 Edition
Examination Overview: This comprehensive certification practice examination contains 150 multiple-choice
questions organized into eight sections, aligned with the CBSPD (Certification Board for Sterile Processing and
Distribution) Flexible Endoscope Reprocessing Certification Standards, ANSI/AAMI ST91 (Flexible and
Semi-Rigid Endoscope Processing in Health Care Facilities), and current endoscope reprocessing competencies.
The examination assesses learner mastery across three cognitive levels: approximately 25% recall (factual
knowledge), 50% application (using knowledge in real-world reprocessing scenarios), and 25% analysis
(evaluating situations and making reprocessing decisions). Approximately 75% of questions are scenario-based,
reflecting real-world endoscope reprocessing situations involving manual cleaning, high-level disinfection, AER
operation, storage, troubleshooting, and quality assurance.

Section 1: Endoscope Fundamentals & Types
Q1: A technician is preparing to reprocess a flexible endoscope used for an ERCP procedure. The
endoscope has an elevator mechanism at the distal tip. Which type of endoscope is this, and what additional
reprocessing consideration does the elevator require?
A. Gastroscope; the elevator does not require special cleaning.
B. Duodenoscope; the elevator wire channel and elevator recess must be manually brushed
and flushed per the IFU, as they are difficult to clean and a common source of
contamination. *[CORRECT]*
C. Colonoscope; the elevator is only found on colonoscopes.
D. Bronchoscope; the elevator is automatically cleaned by the AER.
Correct Answer: B
Rationale: Duodenoscopes used for ERCP have an elevator mechanism at the distal tip with an elevator wire channel
and recessed areas that are difficult to clean and have been linked to outbreaks of multidrug-resistant organisms.
ANSI/AAMI ST91 and FDA guidance require meticulous manual brushing and flushing of the elevator wire channel
per the manufacturer's IFU, in addition to standard reprocessing steps.
Q2: A flexible endoscope has an insertion tube that contains light guide bundles (glass fibers) for
illumination and image guide bundles for image transmission. There is no video camera at the tip. Which
type of endoscope is this?
A. Video endoscope, which has a CCD or CMOS chip at the distal tip.
B. Fiberoptic endoscope, which transmits images through glass fiber bundles to an external
camera or eyepiece. *[CORRECT]*
C. Rigid endoscope, which has a solid metal tube.
D. Semi-rigid endoscope, which has a flexible shaft but rigid tip.
Correct Answer: B
Rationale: Fiberoptic endoscopes use glass fiber bundles (light guide and image guide) to transmit light and images;
the image is viewed through an eyepiece or routed to an external camera. Video endoscopes have a CCD/CMOS chip
at the distal tip that captures the image electronically. The presence of fiber bundles without a distal chip identifies a
fiberoptic endoscope.

Q3: During an inspection, a technician needs to identify the umbilical cord (also called the universal cord)
of a flexible endoscope. Which statement correctly describes the umbilical cord's function?
A. It is the insertion tube that enters the patient.
B. It is the cord that connects the endoscope's control head to the light source processor,
carrying air, water, suction, and electrical connections. *[CORRECT]*
C. It is the angulation control knob cable.
D. It is the biopsy channel access port.
Correct Answer: B
Rationale: The umbilical cord (universal cord) connects the endoscope control head to the light source/electrical
processor. It houses the light guide, air/water, suction, and electrical conduits. The insertion tube enters the patient; the
angulation knobs are on the control head; the biopsy channel access port is on the control head.
Q4: A technician is identifying endoscope channels on a colonoscope. Which set of channels is typically
found on a standard colonoscope?
A. Biopsy/suction channel, air/water channel, and auxiliary water channel only.
B. Biopsy/suction channel and air/water channel (standard channels). *[CORRECT]*
C. Elevator wire channel and forceps elevator channel only.
D. No internal channels; colonoscopes are solid.
Correct Answer: B
Rationale: A standard colonoscope has a biopsy/suction channel (used for both suction and instrument passage) and
an air/water channel (for insufflation and lens washing). The auxiliary water channel is found on some models but is
not universal. The elevator wire channel is specific to duodenoscopes, not colonoscopes.
Q5: A procedure requires direct visualization of the upper GI tract (esophagus, stomach, and duodenum).
Which type of flexible endoscope is most appropriate?
A. Colonoscope, designed for the lower GI tract.
B. Gastroscope, designed for upper GI endoscopy (EGD). *[CORRECT]*
C. Bronchoscope, designed for the respiratory tract.
D. Cystoscope, designed for the urinary bladder.
Correct Answer: B
Rationale: A gastroscope is designed for upper GI endoscopy (esophagogastroduodenoscopy, EGD), allowing
visualization of the esophagus, stomach, and duodenum. A colonoscope is for the lower GI tract, a bronchoscope for
the respiratory tract, and a cystoscope for the urinary bladder. Each scope's length, flexibility, and channel
configuration are tailored to its anatomical target.

Q6: A technician is preparing to reprocess a flexible bronchoscope. Which statement about bronchoscope
channels is most accurate?
A. Bronchoscopes have the same channel configuration as colonoscopes.
B. Bronchoscopes typically have a smaller-diameter suction/biopsy channel and may have an
auxiliary water channel; the channel configuration differs from GI scopes and the IFU
must be followed exactly. *[CORRECT]*
C. Bronchoscopes have no internal channels.
D. Bronchoscopes have an elevator wire channel like duodenoscopes.
Correct Answer: B
Rationale: Bronchoscopes typically have smaller-diameter channels and may include an auxiliary water channel for
irrigation during bronchoalveolar lavage. Their channel configuration differs from GI scopes, and the manufacturer's
IFU must be followed exactly because channel diameters and access ports differ. They do not have an elevator wire
channel (that is duodenoscope-specific).
Q7: A semi-rigid endoscope is being reprocessed. Which statement best describes a semi-rigid endoscope
compared to a fully flexible endoscope?
A. A semi-rigid endoscope has a fully flexible insertion tube like a gastroscope.
B. A semi-rigid endoscope has a rigid or partially rigid shaft with a flexible portion, often used
in urology (e.g., cystoscopes) and ENT procedures; reprocessing must follow the IFU
which may differ from fully flexible scopes. *[CORRECT]*
C. A semi-rigid endoscope is the same as a rigid endoscope.
D. Semi-rigid endoscopes cannot be reprocessed and must be single-use.
Correct Answer: B
Rationale: Semi-rigid endoscopes (e.g., some cystoscopes and ENT scopes) have a rigid or partially rigid shaft
combined with a flexible portion, allowing navigation through curved anatomy while retaining some rigidity. Their
reprocessing must follow the manufacturer's IFU, which may differ from fully flexible endoscopes. ANSI/AAMI
ST91 covers both flexible and semi-rigid endoscope processing.
Q8: A technician is examining the distal tip of a flexible video endoscope. Which component is found at the
distal tip and is responsible for capturing the electronic image?
A. Light guide bundle only.
B. CCD (charge-coupled device) or CMOS image sensor chip. *[CORRECT]*
C. Angulation control knob.
D. Air/water valve.
Correct Answer: B
Rationale: Video endoscopes have a CCD (charge-coupled device) or CMOS image sensor at the distal tip that
captures the image electronically and transmits it to the video processor. The light guide bundle provides illumination,
the angulation knobs are on the control head, and the air/water valve is on the control head.
