What is the full form of SAL?

A.

Sterility Assurance Level
B.

Sterile Asset Limited
C.

Sterilization Assurance Level
D.

Sterility Access Level

Correct Answer
A. Sterility Assurance Level

Explanation
The full form of SAL is Sterility Assurance Level. This term is commonly used in the field of sterilization to indicate the probability of a microorganism surviving on a sterilized product. It is a measure of the effectiveness of the sterilization process and is typically expressed as a logarithmic reduction value. The higher the SAL, the higher the level of sterility assurance.

Hygrometer is an equipment :

A.

To test hedrogen in the atmosphere
B.

To measure height of a CSSD
C.

To check the health of a CSSD technician
D.

To measure the humidity level

Correct Answer
D. To measure the humidity level

Explanation
A hygrometer is an equipment used to measure the humidity level in the atmosphere. It is designed to detect and quantify the amount of moisture present in the air. By accurately measuring the humidity, a hygrometer helps in monitoring and controlling the moisture levels in various environments, such as homes, offices, laboratories, and industrial settings. This information is crucial for maintaining optimal conditions for human comfort, as well as for the preservation of materials, equipment, and processes that may be sensitive to moisture.

Cavitation is related to

A.

Washer Disinfector
B.

Mechanical Cleaning
C.

Ultrasonic Cleaning
D.

Steam Sterilizer

Correct Answer
C. Ultrasonic Cleaning

Explanation
Cavitation is related to Ultrasonic Cleaning. Ultrasonic cleaning uses high-frequency sound waves to create tiny bubbles in a cleaning solution. These bubbles then collapse rapidly, creating a cleaning action called cavitation. The collapse of these bubbles generates high temperatures and pressures, which effectively remove dirt, grease, and contaminants from the surfaces being cleaned. This process is particularly effective for cleaning delicate or intricate items where traditional cleaning methods may not be suitable.

PH of Acidic solution should be

A.

1-5
B.

7
C.

6-10
D.

10-19

Correct Answer
A. 1-5

Explanation
The correct answer is 1-5 because pH is a measure of the acidity or alkalinity of a solution. A pH value below 7 indicates acidity, and the lower the pH value, the stronger the acidity. Therefore, a pH range of 1-5 represents a highly acidic solution.

Example of a sterilant is

A.

Water
B.

Hydrogen Per Oxide
C.

Ethylene Oxide
D.

All of the above

Correct Answer
D. All of the above

Explanation
All of the given options - water, hydrogen peroxide, and ethylene oxide - can act as sterilants. A sterilant is a substance that is capable of killing or eliminating all forms of microbial life, including bacteria, viruses, and fungi. Water can act as a sterilant by heat sterilization methods such as boiling or steam sterilization. Hydrogen peroxide can be used as a sterilant by its strong oxidizing properties, which can destroy microbial cells. Ethylene oxide is a commonly used sterilant in healthcare settings, as it can penetrate and kill microorganisms even in hard-to-reach areas. Therefore, all of the given options can be classified as sterilants.

EO is carcinogenic in nature.

A.

True
B.

False

Correct Answer
A. True

Explanation
EO refers to ethylene oxide, which is indeed carcinogenic in nature. It is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC). Exposure to ethylene oxide has been linked to an increased risk of developing various types of cancer, including leukemia, lymphoma, and breast cancer. Therefore, the statement "EO is carcinogenic in nature" is true.

Plasma Sterilization is suitable for long and narrow lumen.

A.

True
B.

False

Correct Answer
B. False

Explanation
Plasma sterilization is not suitable for long and narrow lumen. Plasma sterilization is a low-temperature sterilization method that uses ionized gas to kill microorganisms on medical devices. However, due to its limited penetration capabilities, plasma sterilization may not effectively reach and sterilize the entire length of long and narrow lumens. Therefore, alternative sterilization methods like ethylene oxide gas sterilization or steam sterilization are more appropriate for such types of medical devices.

Packaging should be done after sterilization.

A.

True
B.

False

Correct Answer
B. False

Explanation
Packaging should be done before sterilization. This is because packaging materials may not be able to withstand the high temperatures and pressures of the sterilization process. If packaging is done after sterilization, there is a risk of contamination and the sterilized items may not remain sterile. Therefore, it is important to package items properly before subjecting them to sterilization.

1. Metal Instruments are the examples of Heat resistant Items. 2. EO has a good penetrable power.

A.

Both 1&2 are right.
B.

Only 1 is right.
C.

Only 2 is right.
D.

Both 1&2 are false.

Correct Answer
A. Both 1&2 are right.

Explanation
1. Metal instruments are known for their ability to withstand high temperatures without getting damaged or deformed. They are commonly used in applications that involve heat, such as cooking utensils, industrial machinery, and scientific equipment. Therefore, metal instruments can be considered as heat resistant items.

2. EO (ethylene oxide) is a highly reactive gas that has excellent penetrating properties. It can easily diffuse through various materials, including plastics, rubber, and fabrics. This characteristic makes EO a valuable sterilization agent in the healthcare industry, where it can effectively reach and kill microorganisms in hard-to-reach areas.

Both statements are correct as metal instruments are heat resistant items, and EO has good penetrable power.

C.

Only 2 is right.
D.

Both 1&2 are false.

Correct Answer
A. Both 1&2 are right.

Explanation
Metal instruments are known for their heat resistance properties as they can withstand high temperatures without getting damaged or deformed. EO (ethylene oxide) is a gas commonly used for sterilization purposes due to its excellent penetrability, allowing it to reach into small crevices and effectively kill microorganisms. Therefore, both statements 1 and 2 are correct.
