What are five protective devices of the body that prevent the entrance of microorganisms.

Explain the difference in RESIDENT flora and TRANSIENT flora.
Resident lives and grows in the deeper layers of the skin (dermis). Transient lives and grows on the superficial skin layers (epidermis)

What should you do when a sharps container in the exam room becomes full?
empty immediately
How should you prepare regulated medical waste for pickup by a medical waste service?
place bio hazard bags and containers in receptacle provided by the MWS. Box should be securely sealed with packing tape and biohazard warning label on two opposite sides of the box/receptacle.
How should regulated medical waste be stored while waiting for pickup by the MWS?
Should be in a locked room inside facility or in a locked collection container outside the facility for P/U. This to help prevent unauthorized access to items such as needles/syringes.
What information is included on a RMW tracking form?

What side effects may occur after the administration of a hepatitis B vaccine?
Soreness at injection site.More serious symptoms are possible but rare.

the administration of a passive and active immunizing agent
What are the symptoms of acute viral hep.B in individuals who have symptoms?
1/3 of the people are asymptomatic.Others may experience mild flu-like symp., some symptoms are so severe that hospital visit may be required . Fatigue, headache, malaise, nausea, vomiting,and muscle/join pain may be possible.
what are some of the symp. of acute HIV infection?
fever, fatigue, losss of app.,diarrhea,myalgia, arthralgia and adenopathy
How does one determine what type of physical or chemical agent to use to destroy microorganisms on an article?
It depends on what the article was used for.
What are two diseases that are caused by bacteria that produce spores?
1) clostridium botulinum -botulism-
2)clostridium tetani -tetanus-
What should be included in a MSDS (Material Safety Date Sheet)?
1) Identification (name/brand name/manufacturer)
2) composition on ingredients
3)Phys./chem. prop.
4)fire/explosion date
5)reactivity data
6)health hazard data
7)emergency first aid procedures
8)precautions for safe handling and use
9)control measures
What info should be included on a hazardous chemical label?
name of chemical, manufacturer info., phys./health hazard of material, safety precautions, storing/handling/disposal of chem.
What is the purpose of sanitizing??
reduces the microorganism count to a safe level
What is the definition of a high-level disinfection?
this destroys all microorganisms with the exception of spores. This is used for semi-critical items
What level disinfection would a flexible fiberoptic sigmoidoscope require?
high-level disinfection
What is the common pressure/temperature used to sterilize materials with the autoclave?
15 lbs. of pressure/ 250 degree Fahrenheit
What are two examples of items that can be disinfected by an intermediate level disinfection?
Stethoscope, BP cuff
Walls and exam tables are two examples of what level of disinfection?
What is the purpose of the pressure used in an autoclave?
it functions to attain a higher temp. than could be achieved by steam alone.
why is it important for all air to be removed from the autoclave during the sterilization process?
Air reduces the temp.
What are three common materials used for wrapping?
1) paper
What is event-related sterility?
When a wrapped article is crushed, compressed or dropped ; the sterility of the contents can not be assumed to be sterile still and the must be rewrapped and resterilized.
How does the medical manufacturing industry use ethylene oxide gas sterilization?
used for heat sensitive articles.
