What parts of the operating room (OR) table
need to be cleaned during a terminal cleaning
(end-of-day)?
- ANSWER-Correct response:
Surface, attachments, base, and wheels
Rationale: Surface, attachments, base, and
wheels. It is important to be thorough during
any cleaning of the OR, but a terminal clean
should be doubly so. Some cases are messier
than others, and it's possible for blood and
bioburden to become trapped in crevices and
within the wheels of the bed.

What bacterial spore is used as a biological
indicator for steam sterilization?
- ANSWER-Correct response:
Geobacillus stearothermophilus
Rationale: Geobacillus stearothermophilus
has been determined to be highly resistant to
being killed by steam, making it ideal to test
the efficacy of steam sterilization. Bacillus
atrophaeus is used as a BI to test Ethylene
oxide and hydrogen peroxide gas plasma
sterilization. Clostridium tetani is a common
soil bacterium and the causative agent of
tetanus. Staphylococcus aureus is a common
bacterium that lives in the human respiratory
tract as well as skin.
How many lobes do the right and left lung
have?
,3|Page
- ANSWER-Correct response:
right = three, left = two
Rationale: The right lung is divided by fissures
(clefts) into three lobes: upper, middle, and
lower. The right lung is shorter and wider
than the left to accommodate the liver. The
left lung is smaller, narrower, and longer than
the right because the heart is normally angled
to the left side in the cardiac notch. The left
lung is subdivided into two lobes: upper and
lower.
These are examples of airborne
contamination, except which one?
- ANSWER-Correct response:
A hair tie accidentally flipped by the nurse
landing on the back table.
, 4|Page
Rationale: The hair tie landing on the sterile
back table is an example of direct contact
transmission; it is not airborne. A cough, a
sneeze, and the plume from a Bovie are all
airborne contaminants.
Sterile supplies and instruments for a case
have been opened in O.R. 1 the surgical tech
was just informed that the case has been
moved to O.R. 2 and the next case in O.R. 1 is
scheduled in 2 hours. Which of the following
is the BEST course of action?
- ANSWER-Correct response:
Obtain new supplies and instruments for O.R.
2 and dispose of the setup in O.R. 1.
Rationale: The best course of action is to
obtain new supplies and instruments for O.R.
2 and dispose of the setup in O.R. 1. Sterility
is crucial in the operating room, and once
