Question 1

Hand washing for routine (nonsurgical) procedures can be performed with antimicrobial or non-antimicrobial soap.

Accepted Answer

In hand washing for routine dental procedures, the physical removal of microbes through vigorous lathering is more important than the nature of the soap being used.

Question 2

Hands should be washed before gloving and after removing gloves.

Accepted Answer

Wash before gloving to reduce the number of skin microbes so there will be fewer to multiply beneath the gloves and irritate the skin.Wash after removing gloves to remove microbes, sweat, and glove material and any patient materials that might have leaked through unnoticed defects in the gloves.

Question 3

Which of the following is the correct hand hygiene procedure for using an alcohol hand rub before surgery?&#10;A)Use alcohol hand rub; rinse; dry.&#10;B)Wash with a non-antibacterial soap; rinse; dry; use alcohol hand rub.&#10;C)Use alcohol hand rub; wash with non-antibacterial soap; rinse; dry.&#10;D)Wash with non-antibacterial soap; use alcohol hand rub; dry.

Accepted Answer

The correct procedure involves washing hands with non-antibacterial soap to remove visible dirt and organic material, then drying them before applying an alcohol-based hand rub to ensure the hands are disinfected. This sequence is recommended to maximize the removal of potential pathogens before surgery.

Question 4

Why is it important to wash the hands before gloving?&#10;A)The residual moisture from hand washing makes the gloves easier to put on.&#10;B)The small amount of soap left on the hands after hand washing prevents any allergic reaction to the gloves.&#10;C)Dirty hands increase the chance that the gloves will tear during use.&#10;D)This reduces the number of microbes on the skin so there will be fewer to multiply beneath the gloves and irritate the skin.

Accepted Answer

Washing the hands before gloving is important to reduce the number of microbes on the skin. This is necessary because gloves may not provide complete protection against infection or contamination. If the number of microbes on the skin is not reduced before putting on the gloves, there will be more microbes to multiply beneath the gloves and irritate the skin. Hence, it is important to wash the hands before gloving. Option A is not relevant to the context as gloves are designed to fit snugly irrespective of the moisture on the hands. Option B is also irrelevant as residual soap left on the hands may not necessarily prevent allergic reactions to gloves. Option C is not a strong reason to support the importance of washing hands before gloving.

Question 5

Which type of hand lotion will not have detrimental effects on latex gloves?&#10;A)Glycerin&#10;B)Lanolin&#10;C)Palm oil&#10;D)Petrolatum

Accepted Answer

Glycerin-based hand lotions are compatible with latex gloves and do not degrade them, unlike lotions containing oils or petroleum-based ingredients which can weaken latex.

Question 6

What is the antimicrobial agent in hand rubs used without rinsing?&#10;A)Sodium hypochlorite&#10;B)Hydrogen peroxide&#10;C)Alcohol&#10;D)Glutaraldehyde

Accepted Answer

Alcohol is the most common antimicrobial agent in hand rubs used without rinsing. It is effective against a wide range of microorganisms and evaporates quickly, reducing the risk of contamination. Sodium hypochlorite and hydrogen peroxide are typically used as disinfectants for surfaces and equipment, while glutaraldehyde is a high-level disinfectant for medical instruments.

Question 7

When alcohol-based hand rubs are used throughout the day, which of the following should be done?&#10;A)Periodically wash the gloves to remove the residual alcohol.&#10;B)Perform a surgical scrub using antimicrobial soap at the end of the day because alcohol-based hand rubs are not very effective.&#10;C)Wash and rinse the hands after every four to five hand rubs to remove the buildup of glove powder, sweat, and glove chemicals from the hands.&#10;D)For every other hand rub, put the gloves on first and then use the alcohol-based hand rub.

Accepted Answer

While alcohol-based hand rubs are effective in killing germs, they can cause a buildup of glove powder, sweat, and glove chemicals on the hands. Washing and rinsing the hands after every four to five hand rubs can help to remove this buildup and prevent skin irritation. Options A, B, and D are not necessary or appropriate actions when using alcohol-based hand rubs.

Question 8

Which of the following best describes the resident skin flora on the hands?&#10;A)Microbes that live on the skin all the time&#10;B)Microbes that are usually killed or removed by handwashing&#10;C)Microbes that are usually involved in the spread of disease from the hands&#10;D)Microbes that are highly pathogenic

Accepted Answer

The resident skin flora on the hands refers to the microbes that live on the skin all the time, and are not easily removed by handwashing. This includes bacteria, fungi, and viruses that are a natural part of the human microbiome, and do not typically cause disease.

Question 9

Which of the following procedures provides the least cross-contamination during hand washing?&#10;A)Using electric eye soap dispensers&#10;B)Using bar soaps&#10;C)Using squeeze bottle soap dispensers&#10;D)Using pump soap dispensers

Accepted Answer

Using electric eye soap dispensers provides the least cross-contamination during hand washing as it eliminates the need to touch the dispenser, reducing the spread of germs between users. Bar soaps, squeeze bottle soap dispensers and pump soap dispensers all require some degree of contact and can be a potential source of cross-contamination.

Question 10

Which property of hand hygiene agents is least important to consider before making a selection to purchase?&#10;A)Antimicrobial action&#10;B)Method of dispensing&#10;C)Persistence of activity&#10;D)Size of the container

Accepted Answer

The size of the container is the least important factor to consider when selecting a hand hygiene agent, as it does not affect the effectiveness or function of the product. However, it may be a consideration for practicality and convenience in terms of storage and usage frequency.
