Morgan & Mikhail Reading Exam 1 (Ch.
2-4) questions with answers
a pressure of _____ indicates an E-cylinder that is approximately 1/2
full, and represents 330 L of oxygen (at atmospheric pressure and a
temperature of 20 C) - CORRECT ANSWERS ✔✔1000 psig
a pressure of 1000 psig indicates an E-cylinder that is approximately
HALF full, and represents ____ - CORRECT ANSWERS ✔✔330 L of
oxygen
the only reliable way to determine residual volume of nitrous oxide is
to ____ - CORRECT ANSWERS ✔✔weigh the cylinder
to discourage incorrect cylinder attachments, cylinder manufacturers
have adopted a ___ - CORRECT ANSWERS ✔✔pin index safety
system
,a basic principle of radiation safety is to keep exposure ______ -
CORRECT ANSWERS ✔✔as low as reasonably practical (ALARP)
the principles of ALARP are ____ - CORRECT ANSWERS
✔✔protection from radiation exposure by the use of:
- TIME
- DISTANCE
- SHIELDING
the magnitude of a leakage current is normally imperceptible to
touch, ____ - CORRECT ANSWERS ✔✔less than 1 mA
fibrillation threshold of current - CORRECT ANSWERS ✔✔100 mA
,if a leakage current of < 1 mA bypasses the high resistance offered
by skin and is applied directly to the heart (MICROSHOCK), current
as low as ____ may be FATAL - CORRECT ANSWERS ✔✔100
microA
the maximum leakage current allowed in operating room equipment
is ___ - CORRECT ANSWERS ✔✔10 microA
to reduce the chance of 2 co-existing faults, a ____ measures the
potential for current flow from the isolated power supply to the
ground - CORRECT ANSWERS ✔✔line isolation monitor
(it determines the degree of isolation between the 2 power wires and
the ground, and predicts the amount of current that COULD flow if a
2nd short circuit were to develop)
almost all ____ can be prevented - CORRECT ANSWERS
✔✔surgical fires
unlike medical complications, ____ are a product of simple physical
and chemistry properties; occurrence is guaranteed given the proper
combination of factors but can be eliminated almost entirely by
understanding the basic principles of risk - CORRECT ANSWERS
✔✔fires
, likely the MOST COMMON risk factor for surgical fires relates to
____ - CORRECT ANSWERS ✔✔the open delivery of oxygen
administration of oxygen to concentrations of greater than ____
should be guided by clinical presentation of the patient and not
solely by protocols or habits - CORRECT ANSWERS ✔✔30%
the SEQUENCE of ____ when fire occurs in the airway is not as
important as ensuring that both actions are performed QUICKLY! -
CORRECT ANSWERS ✔✔- stopping gas flow
- removal of the ETT
before beginning laser surgery, ____ - CORRECT ANSWERS ✔✔-
the laser device should be in the OR
- warning signs should be posted on the doors
- protective eyewear should be issued
the anesthesia provider should ensure that ____, as laser protection
is specific to the type of laser - CORRECT ANSWERS ✔✔the
warning signs and eyewear match the labeling on the laser device
