1.
Which of the following is considered the most important aspect of handwashing?
Correct Answer
C. Friction
Explanation
Friction is considered the most important aspect of handwashing because it helps to physically remove dirt, germs, and bacteria from the hands. While soap and water are necessary components of handwashing, it is the friction created by rubbing the hands together that helps to dislodge and wash away any contaminants. Without sufficient friction, the effectiveness of handwashing is greatly reduced, regardless of the presence of soap or water. Time is also important, as hands should be washed for at least 20 seconds, but friction is the key factor in ensuring proper hand hygiene.
2.
What is the time duration for medical hand washing?
Correct Answer
C. 40 to 60 seconds
Explanation
Medical hand washing is a crucial practice in healthcare settings to prevent the spread of infections. The recommended time duration for medical hand washing is 40 to 60 seconds. This duration allows for thorough cleaning of the hands, including all surfaces and between the fingers. It ensures that any harmful microorganisms present on the hands are effectively removed. A shorter duration may not be sufficient to eliminate all germs, while a longer duration may not provide additional benefits and can lead to skin dryness or irritation.
3.
What is the time duration for surgical handwashing?
Correct Answer
D. 3 to 5 minutes
Explanation
The correct answer is 3 to 5 minutes. Surgical handwashing is a crucial step in preventing infections in the operating room. It involves a thorough cleaning of hands and forearms using an antiseptic solution. The recommended time duration for surgical handwashing is typically 3 to 5 minutes. This duration allows for adequate removal of microorganisms from the skin surface, reducing the risk of contamination during surgery.
4.
How many steps are in the handwashing procedure?
Correct Answer
B. 7
Explanation
There are seven steps in the handwashing procedure.
5.
Performing hand hygiene using antiseptic hand rub, the nurse would continue to rub how long?
Correct Answer
C. Until antiseptic evaporated from the skin
Explanation
The correct answer is "Until antiseptic evaporated from the skin." This is because the purpose of using an antiseptic hand rub is to kill or inhibit the growth of microorganisms on the hands. The antiseptic needs time to work effectively, and rubbing the hands until the antiseptic has evaporated ensures that enough contact time has been given for the antiseptic to do its job.
6.
The nurse is washing his or her hands. What should be done first?
Correct Answer
B. Remove jewelry
Explanation
Before the nurse can wash their hands, they should first remove any jewelry they may be wearing. This is important because jewelry can harbor bacteria and make it difficult to properly clean and sanitize the hands. By removing jewelry, the nurse ensures that their hands are free of any potential contaminants and can be thoroughly cleaned.
7.
When washing hands with soap and water which of the following would be most appropriate?
Correct Answer
A. Using rubbing circular motions
Explanation
Using rubbing circular motions is the most appropriate method when washing hands with soap and water. This technique helps to ensure that all areas of the hands are thoroughly cleaned, including the palms, backs of the hands, fingers, and nails. Rubbing circular motions create friction, which helps to remove dirt, bacteria, and viruses from the skin. It is important to wash hands for at least 20 seconds using this technique to effectively reduce the risk of spreading germs and infections.
8.
When should you practice hand hygiene:
Correct Answer
A. Both before and after having contact with the patient
Explanation
Hand hygiene should be practiced both before and after having contact with the patient. This is because before contact, hand hygiene helps to prevent the transmission of any potential pathogens from the healthcare worker to the patient. After contact, hand hygiene is necessary to remove any potential pathogens acquired from the patient and prevent their transmission to other patients or surfaces. Practicing hand hygiene in both instances helps to maintain a clean and safe healthcare environment.
9.
It is a necessary to practice hand hygiene after wearing disposable gloves during contact with the patient or equipment connected to the patient.
Correct Answer
B. False
Explanation
It is not necessary to practice hand hygiene after wearing disposable gloves during contact with the patient or equipment connected to the patient. Disposable gloves are designed to provide a barrier between the wearer's hands and potentially infectious materials. However, it is important to remove and dispose of the gloves properly after use to prevent cross-contamination. Hand hygiene should be performed before and after glove use to ensure proper infection control.
10.
If a hand sanitizer is taking too long to dry it is OK to use a paper towel to dry them off and help the process move along faster.
Correct Answer
B. False
Explanation
Using a paper towel to dry off hand sanitizer will not help the process move along faster. Hand sanitizers contain alcohol, which evaporates quickly on its own. Adding a paper towel will not speed up the drying process. It is best to let the hand sanitizer air dry naturally.
