when an emergency situation arises is called:
Emergency sterilization
Flash sterilization
Core sterilization
Rapid reprocessing -✓✓Flash sterilization
• In order to elevate the temperature in a steam sterilizer,you must:
Increase the steam pressure
Decrease the steam pressure
Archieve ambient pressure
Inject boiler amines -✓✓Increase the steam pressure
• This surgical procedure is the removal of a testicle.
Transurethral Resection
Prostatectomy
Orchiopexy
Orchiectomy -✓✓Orchiectomy
• When placing ring handled instruments in an instrument tray,you should:
Lock the handles to prevent damage during sterilization
Arrange the instruments in alphabetical order
Arrange the instruments in the order of their use
Unlock the handles and open the instruments -✓✓Unlock the handles and open the
instruments
• Which of the following kills microorganisms?
Soaps
Detergents
Germicidal presoaks
Enzyme presoaks -✓✓Germicidal presoaks
• Germicidal presoaks are specifically designed to kill microorganisms. They contain
chemicals or agents that have antimicrobial properties, which can effectively eliminate
bacteria, viruses, and other harmful microorganisms. Soaps and detergents, on the
other hand, may help in removing dirt and grime but do not necessarily kill
microorganisms. Enzyme presoaks are used to break down organic stains but do not
have germicidal properties. Therefore, germicidal presoaks are the most appropriate
choice for killing microorganisms. -✓✓Germicidal presoaks
,• The sterile storage area in a Central Service department should be restricted to:
Central Service managers and supervisors
Operating Room personnel
Central Service employees only

modulation in order to reduce risk of deep vein thrombosis (DVT)
Gastric suction unit
Sequential compression device
IV pump
Defribilator -✓✓Sequential compression device
• a plastic, air filled sleeve that is placed around the leg and inflates and deflates
regularly to help improve circulation, reduce fluid build up, and prevent blood clots -
✓✓Sequential compression device
• Departmental dress code apply to:
Everyone entering the Central Service department

• Compounds that contain a positive electrical charge. They exhibit germicidal
properties.
Cationic
Anionic -✓✓Cationic
• Cationic compounds are substances that carry a positive electrical charge. These
compounds have the ability to exhibit germicidal properties, meaning they can kill or
inhibit the growth of microorganisms. This is due to their positive charge, which allows
them to interact with negatively charged components of microorganisms, disrupting their
cellular processes and ultimately leading to their death. Therefore, cationic compounds
are effective in disinfection and sanitation applications. -✓✓Cationic
• When speaking, you should
Be influenced by the listeners emotions
Concentrate on the listener rather than oneself
Use technical jargon to impress the listener

True
False -✓✓True
• What is a surface-acting agent that lowers the surface tension of liquid so it can
penetrate deeper and prevent debris from being re-deposited on the item to which the
soil was attached?
Descaler
Surfactant
Wetting Agent
Softener -✓✓Surfactant
• A surfactant is a surface-acting agent that lowers the surface tension of a liquid,
allowing it to penetrate deeper into materials. This property helps to prevent debris from
being re-deposited on the item from which the soil was removed. Surfactants are
, commonly used in cleaning and detergents to enhance the efficiency of cleaning
processes by ensuring thorough contact with the surface. -✓✓Surfactant
