Reveiw quiz for chapter 6

• 1.

### What is the correct temp of decontamination

Explanation
The correct temperature for decontamination is 60-65 degrees. This temperature range is considered ideal for killing pathogens and bacteria effectively. It ensures that the decontamination process is thorough and efficient, reducing the risk of contamination or infection. Maintaining the correct temperature range is crucial to ensure the safety and effectiveness of the decontamination process.

Rate this question:

• 2.

### What is the humidity for decontam

Explanation
The humidity for decontamination should be maintained between 30-60. This range is considered ideal for effective decontamination processes. Humidity levels below 30 may cause the environment to be too dry, leading to ineffective decontamination. On the other hand, humidity levels above 60 may create a damp environment, which can promote the growth of bacteria and other contaminants. Therefore, maintaining a humidity range of 30-60 is crucial for successful decontamination procedures.

Rate this question:

• 3.

### How many air exchanges per hour in decontam

Explanation
The given answer states that there are 10 air exchanges per hour in decontamination. This suggests that the air inside the decontamination area is completely replaced with fresh air 10 times every hour. This high rate of air exchanges helps to remove any contaminants or pollutants present in the air, ensuring a clean and safe environment for the decontamination process.

Rate this question:

• 4.

### What is the temp for packaging area

Explanation
This answer suggests that the temperature range for the packaging area is between 68 and 73 degrees.

Rate this question:

• 5.

### What is the humidity for packaging

Explanation
The humidity range of 30-60 is considered ideal for packaging. This range helps to maintain the quality and integrity of the packaged products. If the humidity is too low, it can cause the products to dry out or become brittle. On the other hand, if the humidity is too high, it can lead to moisture damage, mold growth, or spoilage of the packaged items. Therefore, maintaining a humidity level between 30-60 ensures that the packaging environment is suitable for preserving the quality and freshness of the products.

Rate this question:

• 6.

### What is the air exchange per hour for packaging

Explanation
The air exchange per hour for packaging is 10. This means that every hour, 10 units of air are exchanged within the packaging. This could refer to the amount of fresh air that enters the packaging or the amount of stale air that is removed from the packaging. It is important to have proper air exchange in packaging to maintain the quality and freshness of the contents inside.

Rate this question:

• 7.

### What is the temp for sterile storage

Explanation
The correct answer is 75 or less because sterile storage requires maintaining a controlled temperature to prevent the growth of microorganisms. A temperature of 75 or less helps to inhibit bacterial growth and maintain the sterility of stored items. Higher temperatures can promote bacterial proliferation and compromise the sterility of the stored items. Therefore, keeping the temperature at 75 or below is crucial for ensuring the effectiveness of sterile storage.

Rate this question:

• 8.

### What is the humidyt for sterile storage

Explanation
The humidity for sterile storage should be maintained at a level less than 70. This is because higher humidity levels can promote the growth of microorganisms, which can compromise the sterility of the stored items. By keeping the humidity below 70, the risk of microbial contamination is reduced, ensuring the integrity and safety of the sterile storage environment.

Rate this question:

• 9.

### How many air exchanges per hour in sterile storage

Explanation
The answer is 4 because air exchanges per hour in sterile storage refers to the number of times the air in the storage area is completely replaced with fresh air within an hour. This is important in maintaining a sterile environment to prevent the accumulation of contaminants and ensure the quality of stored items. Having 4 air exchanges per hour indicates a high level of air circulation and filtration, which helps to minimize the risk of contamination and maintain sterility.

Rate this question:

• 10.

### Each Year approximately _____ patients develop a healthcare associated infection

• A.

1 million

• B.

2 million

• C.

10 million

• D.

20 million

B. 2 million
Explanation
Approximately 2 million patients develop a healthcare-associated infection each year. This suggests that a significant number of individuals acquire infections while receiving medical care. This highlights the importance of infection prevention and control measures in healthcare settings to minimize the risk of such infections. It also emphasizes the need for robust surveillance and monitoring systems to track and address these infections effectively.

Rate this question:

• 11.

### Watches and other jewelry should not be worn in the central service department work areas because

• A.

They harbor bacteria

• B.

They are expensive

• C.

They may be damaged

• D.

They may be misplaced or stolen

A. They harbor bacteria
Explanation
Watches and other jewelry should not be worn in the central service department work areas because they can harbor bacteria. Bacteria can easily accumulate on the surfaces of jewelry, especially in areas where hands come into contact with various objects and surfaces. This can pose a risk to both the wearer and others in the work area, as bacteria can easily spread and cause infections. Therefore, to maintain a clean and hygienic work environment, it is advisable to avoid wearing jewelry that can harbor bacteria.

Rate this question:

• 12.

### During handwashing hands should be lathered and scrubbed for at least

• A.

10 sec

• B.

15 sec

• C.

1 min

• D.

2 min

B. 15 sec
Explanation
The correct answer is 15 seconds because research has shown that lathering and scrubbing hands for at least 15 seconds is sufficient to effectively remove germs and bacteria. This duration allows enough time for the soap to create a lather, which helps to break down and remove dirt and microorganisms from the hands. Washing for shorter durations may not provide adequate cleaning, while washing for longer durations may not offer any additional benefits in terms of germ removal. Therefore, 15 seconds is the recommended minimum time for handwashing.

Rate this question:

• 13.

### To protect themselves from splashes and spills central service techs assigned to the decontamination area should wear

• A.

Double cloth gowns

• B.

Blue surgical scrubs

• C.

Fluid resistant gowns

• D.

Sterile operating room gowns

C. Fluid resistant gowns
Explanation
Central service techs assigned to the decontamination area should wear fluid resistant gowns to protect themselves from splashes and spills. These gowns are designed to repel fluids and provide a barrier against potential contamination. They are specifically made to withstand contact with liquids and prevent them from seeping through to the technician's clothing or skin. Wearing fluid resistant gowns helps ensure the safety and hygiene of the techs while they handle potentially hazardous materials in the decontamination area.

Rate this question:

• 14.

### The main theory of standard precautions is that

• A.

Patients in high risk categories may be infectious

• B.

Patients diagnosed with a specific disease may be infectious

• C.

Patients are generally healthy unless they show symptoms of an infectious disease

• D.

Patients may pose a risk of infection whether they have been diagnosed with an infectious disease or not

D. Patients may pose a risk of infection whether they have been diagnosed with an infectious disease or not
Explanation
The main theory of standard precautions is that patients may pose a risk of infection whether they have been diagnosed with an infectious disease or not. This means that healthcare providers should treat all patients as potentially infectious and take necessary precautions to prevent the spread of infections. It emphasizes the importance of practicing infection control measures consistently, regardless of the patient's health status or specific diagnosis. This approach helps to protect both healthcare providers and patients from the transmission of infectious diseases.

• A.

Wet mopped daily

• B.

Wet mopped weekly

• C.

Swept daily and wet mopped weekly

• D.
