numbness, blurred vision, and dizziness. What should be the immediate action
of the perioperative nurse monitoring this patient?
a. Recheck the dose of local anesthesia given
b. Ensure an airway
c. Set the IV line to full flow
d. Call for 20% lipid emulsion to be brought to the room - answer-b
The circulating nurse reports that the needle count is incorrect. The surgeon
continues to close the wound, stating, "I know it is not in the wound and I am
not going to stop to look for it." The best plan of action is to:

report

,c. Order X-rays regardless of the surgeon's wishes
d. Notify the OR supervisor and ask for advice - answer-b
*Types of Sterilization*
__________:
-Cold & dry
-For heat and moisture sensitive items
-99-145 degrees F and 45-75% humidity
-2-5 hours exposure (total of ~17 hours for one run)
-Aeration time 8-12 hours
-HUMAN CARCINOGEN (known to cause cancer, will MELT LUNGS)
-Exposure time limited to 1 ppm in an 8-hour period (workers must leave area
immediately if exposure exceeds)
-Wonderful for instruments
-Lumens must be COMPLETELY DRY
-Environmentally hazardous
-The only way to sterilize long, narrow lumens inside of a package (ex. foley
catheters) - going to be BANNED in 2030, so we need to come up with a
different way to sterilize
-Banned in Europe, so Europe buys from us - answer-ethylene oxide
,*Types of Sterilization*
__________:
-Cold & dry
-Sterrad or V-PRO
-Used for heat and moisture sensitive items
-Electrical current changes hydrogen peroxide into a plasma
-Cycle time is 75 minutes (even if the cycle aborts due to wet items, it is still 75
minutes)
-Environmentally sound
-Items MUST BE DRY, plasma cannot reach instrument if there's a bead of
water
-Waste product is oxygen and water
-Does NOT sterilize long narrow lumens inside of a package; must be forced
through the lumens, so these instruments CANNOT be in a package - answer-
low temperature hydrogen peroxide plasma sterilization
*Types of Sterilization*
__________:
-Very acidic like stomach acid
-Used a lot in GI labs
-Automated Endoscope Reprocessor (AER)
-For items that can be immersed
, -Corrosive to instruments and people
-Temp 120-130 degrees F
-20-30 minutes
-Micron filtered tap water rinses - FOUR OF THEM (turns it into vinegar, which
is then OK for it to go down the drain and into regular sewage), very acidic so
cannot go on someones skin until rinsed four times
-For point of care use only (must be dried and stored appropriately OR used
immediately; won't wrap them in a package somewhere
-Documentation (for patient safety) - answer-peracetic acid
*Types of Sterilization*
__________:
-Low temperature sterilization
-Only one manufacturer in the USA
-FDA has cleared this for sterilization of METAL and PLASTIC
-Exhaust is passed through a CATALYTIC CONVERTER
-Environmentally sound (biproduct is oxygen and water)
-No aeration cycle is necessary - answer-ozone
*Types of Sterilization*
__________:
-High temperature
