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 washing hands, it's important to remove any jewelry that could harbor microorganisms or interfere with the cleaning process. Rings, bracelets, and watches can create hard-to-reach areas where germs can persist. Once jewelry is removed, the remaining steps can be followed in order: turn on the tap, wet hands, apply soap, lather and scrub for at least 20 seconds, clean under nails, rinse thoroughly, and dry hands with a clean towel or air dry.
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
A. True
Explanation
It is necessary to practice hand hygiene after wearing disposable gloves during contact with a patient or equipment connected to the patient. Gloves can carry microorganisms from one surface to another, and they are not entirely foolproof in preventing contamination. Additionally, removing gloves can transfer contaminants to your hands, which is why proper hand hygiene (like washing hands with soap and water or using hand sanitizer) is essential even after wearing disposable gloves. This practice helps prevent the spread of infections and maintains patient and healthcare worker safety.
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.
