The preferred cleansing solution for buttonhole cannulation sites is,
- A.
Providone 1%
- B.
Chlorhexidine 2%
- C.
Chlorhexidine 4%
- D.
Alcohol
Correct Answer
B. Chlorhexidine 2%Explanation
Chlorhexidine 2% is the preferred cleansing solution for buttonhole cannulation sites. It is a commonly used antiseptic that has broad-spectrum activity against various microorganisms. It is effective in reducing the risk of infections at the cannulation site. Povidone 1% is also a commonly used antiseptic, but it may not be as effective as chlorhexidine in preventing infections. Chlorhexidine 4% is a higher concentration and may be too strong for use on the skin. Alcohol is not recommended as a cleansing solution for buttonhole cannulation sites as it may not effectively kill all microorganisms and can cause skin dryness.Rate this question:

- C.
Don face shield, wash hands, don gloves, cleanse sites, soak sites.
- D.
None of the above
Correct Answer
C. Don face shield, wash hands, don gloves, cleanse sites, soak sites.Explanation
The correct sequence of events prior to buttonhole site scab removal is to first don a face shield to protect against any splashes or sprays. Then, wash hands thoroughly to ensure cleanliness. Next, don gloves to maintain a sterile environment. After that, cleanse the buttonhole sites to remove any dirt or debris. Finally, soak the sites to soften the scabs before removing them. This sequence ensures proper hygiene and safety measures are followed before performing the procedure.Rate this question:

It is preferred that scabs covering the buttonhole sites are removed,
- A.
Carefully with a sharp sterile needle.
- B.
Carefully with a dull sterile needle.
- C.
Carefully with tweezers.
- D.
By applying friction with a gauze when cleansing.
Correct Answer
B. Carefully with a dull sterile needle.Explanation
The scabs covering the buttonhole sites should be removed carefully with a dull sterile needle. Using a sharp needle can increase the risk of injury or infection, while using tweezers or applying friction with a gauze may cause unnecessary pain or damage to the skin. A dull sterile needle is the safest and most effective tool for gently removing the scabs without causing any harm.Rate this question:

Each scab should be removed with,
- A.
The same sterile needle for both sites.
- B.
A separate dull sterile needle for each site.
- C.
A separate clean gauze for each site during the cleansing step.
- D.
The same tweezers for both sites
Correct Answer
B. A separate dull sterile needle for each site.Explanation
The correct answer is to use a separate dull sterile needle for each site. This is important to prevent the spread of infection. Using the same needle for both sites can introduce bacteria from one site to the other, increasing the risk of infection. Using a separate needle for each site ensures that the scabs are removed in a sterile manner, reducing the risk of complications.Rate this question:

Following scab removal the buttonhole sites should be,
- A.
Recleansed.
- B.
Cannulated.
- C.
Visualized with the portable ultrasound.
- D.
Palpated.
Correct Answer
A. Recleansed.Explanation
After the scab removal, the buttonhole sites should be recleansed. This is important to ensure that the area is clean and free from any potential infection. Recleansing helps to remove any debris or bacteria that may have accumulated during the scab formation. It also helps in preventing any further complications or infections that can occur if the site is not properly cleaned. Cannulation, visualization with portable ultrasound, and palpation are not necessary steps after scab removal and do not address the need for cleansing the buttonhole sites.Rate this question:

- 6.
If a patient cleans their own buttonhole sites and removes the scabs but does not self cannulate the cannulator should,
- A.
Continue with cannulation after the patient has cleaned the sites.
- B.
Recleanse the sites then proceed with cannulation.
- C.
Instruct the patient on how to self cannulate.
- D.
None of the above.
Correct Answer
B. Recleanse the sites then proceed with cannulation.Explanation
If a patient cleans their own buttonhole sites and removes the scabs but does not self cannulate, it is important for the cannulator to recleanse the sites before proceeding with cannulation. This is necessary to ensure that the sites are properly cleaned and free from any potential contaminants. By recleansing the sites, the cannulator can minimize the risk of infection and ensure a safe and successful cannulation procedure. Instructing the patient on how to self cannulate may be an option in the future, but in this particular situation, the priority is to recleanse the sites before proceeding.Rate this question:

When the needles have been removed and hemostasis has occurred,
- A.
Gauze should be placed over the cannulation sites.
- B.
The sites should be cleansed then covered with gauze.
- C.
Polysporin ointment should be applied to the gauze then to the cannulation sites.
- D.
The sites should be left open to air to promote healing.
Correct Answer
C. Polysporin ointment should be applied to the gauze then to the cannulation sites.Explanation
After the needles have been removed and hemostasis has occurred, it is recommended to apply polysporin ointment to the gauze and then to the cannulation sites. This helps prevent infection and promotes healing by creating a barrier between the wound and external contaminants. Applying the ointment directly to the sites without the gauze may cause discomfort and may not provide adequate protection.Rate this question:
