WHAT IS THE BUMEDINST FOR DISINFECTION AND STERILIZATION?
- A.
6600.10 SERIES
- B.
6601.10 SERIES
- C.
6600/10 SERIES
- D.
6601/10 SERIES
Correct Answer
A. 6600.10 SERIESExplanation
The correct answer is 6600.10 SERIES. This series refers to the BUMEDINST (Bureau of Medicine and Surgery Instruction) for disinfection and sterilization. It is likely a set of guidelines or protocols that healthcare professionals follow to ensure proper disinfection and sterilization procedures are carried out.Rate this question:

WHAT ARE THE 2 STERILIZATION METHODS?
- A.
PHYSICAL
- B.
CHEMICAL
- C.
PHYSICAL AND CHEMICAL
Correct Answer
C. pHYSICAL AND CHEMICALExplanation
The correct answer is "PHYSICAL AND CHEMICAL" because sterilization methods can be categorized into two main types: physical and chemical. Physical sterilization methods involve the use of heat, radiation, or filtration to kill or remove microorganisms. Chemical sterilization methods, on the other hand, use chemicals such as gases or liquids to destroy or inhibit the growth of microorganisms. Therefore, the correct answer is physical and chemical, as both types of sterilization methods are commonly used in various industries and healthcare settings.Rate this question:

pHYSICAL STERILIZATION: - MOIST HEAT UNDER PRESSURE - DRY
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given answer "True" is correct because physical sterilization methods include both moist heat under pressure and dry heat. Moist heat under pressure is commonly used in autoclaves to kill microorganisms by denaturing their proteins and destroying their cell walls. Dry heat sterilization involves using high temperatures to kill microorganisms by oxidation. Both methods are effective in sterilizing equipment and materials.Rate this question:

CHEMICAL STERILIZATION: - GAS - LIQUID
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Chemical sterilization can be achieved using both gas and liquid methods. Gas sterilization involves using gases such as ethylene oxide or hydrogen peroxide vapor to kill microorganisms on surfaces or in enclosed spaces. Liquid sterilization, on the other hand, involves immersing objects in a liquid sterilant, such as glutaraldehyde or peracetic acid, to achieve sterilization. Therefore, the statement "Chemical sterilization can be achieved using gas and liquid" is true.Rate this question:

- B.
110 C (245 F)
- C.
120 C (240 F)
- D.
121 C (250 F)
Correct Answer
D. 121 C (250 F)Explanation
The correct answer is 121 C (250 F). At this temperature, it is known to kill all organisms.Rate this question:

A TYPICAL DRY HEAT CYCLE IS _____ MINTUES AND AT WHAT TEMPERATURES?
- A.
30 MINS AT 320 F TO 345 F
- B.
60 MINS AT 320 F TO 345 F
- C.
90 MINS AT 320 F TO 345 F
- D.
120 MINS AT 320 F TO 345 F
Correct Answer
C. 90 MINS AT 320 F TO 345 FExplanation
A typical dry heat cycle lasts for 90 minutes and operates at temperatures between 320°F to 345°F.Rate this question:

IF THE AIR HAS BEEN REMOVED FROM THE CHAMBER DURING THE PERVACUUM STAGE WHAT TYPE OF TEST IS THIS?
- A.
DICK-BOWIE
- B.
BOWIE-DICK
- C.
PERVACUUM TEST
- D.
CHAMBER TEST
Correct Answer
B. BOWIE-DICKExplanation
The correct answer is BOWIE-DICK. The Bowie-Dick test is a type of test that is performed to evaluate the effectiveness of air removal and steam penetration in a sterilization chamber. This test is specifically designed to detect air leaks and inadequate air removal in the chamber. Therefore, if the air has been removed from the chamber during the pre-vacuum stage, it indicates that the Bowie-Dick test is being conducted.Rate this question:

WHAT IS THE EXPOSURE TIME AND TEMPERATURE FOR CHEMICAL VAPOR STERILIZATION?
- A.
10-20 MINS AT 250 F
- B.
20-30 MINS AT 265 F
- C.
20-40 MINS AT 270 F
- D.
30-40 MINS AT 275 F
Correct Answer
C. 20-40 MINS AT 270 FExplanation
Chemical vapor sterilization is a method used to sterilize medical equipment and instruments. The exposure time and temperature required for this process are crucial to ensure effective sterilization. The correct answer, 20-40 minutes at 270°F, indicates that the equipment needs to be exposed to the chemical vapor for a duration of 20 to 40 minutes at a temperature of 270°F. This specific combination of time and temperature is necessary to achieve the desired level of sterilization and ensure the safety of the equipment being sterilized.Rate this question:
