Infection Prevention 2021 - CNA Competency Quiz

Patients who are being ruled out for or have tested positive for tuberculosis should be placed on airborne precautions. This is because tuberculosis is primarily transmitted through the air when an infected individual coughs, sneezes, or talks, releasing tiny droplets containing the bacteria. Airborne precautions, such as wearing a specialized mask (N95 respirator) and placing the patient in a negative pressure room, help prevent the spread of the bacteria to healthcare workers and other patients.

Patients on Contact, Enteric, Enhanced, or Droplet Isolation should have a clean sheet placed over their linens when being transported within the hospital. This is because these patients may have infectious diseases or conditions that can spread through contact or droplets. Placing a clean sheet over their linens helps to prevent the transmission of pathogens to other areas of the hospital.

If a patient is on PUI/COVID+ transmission precautions, the appropriate PPE is gown, gloves, surgical mask, N95/PAPR, and eye protection.

In an isolation room, the primary goal is to prevent the spread of infectious diseases. Bringing in only essential equipment helps minimize the risk of contamination and transmission of pathogens. Additional equipment can introduce unnecessary surfaces that may harbor germs and increase the chances of cross-contamination. Therefore, it is crucial to limit the items brought into an isolation room to essential equipment only.

Patients on enteric and enhanced precautions should receive their meals on a disposable tray with disposable utensils. Enteric precautions are designed to prevent the spread of infections caused by microorganisms that are present in the gastrointestinal tract, such as Clostridium difficile. Enhanced precautions are taken for patients with infections that require additional measures beyond standard precautions, such as those caused by multidrug-resistant organisms. Using disposable trays and utensils helps to minimize the risk of cross-contamination and transmission of these pathogens.

When entering or exiting the room of a patient on enteric precautions, it is necessary to use soap and water to wash your hands. This is because soap and water are more effective at removing and killing the pathogens that may be present on your hands. Alcohol-based hand sanitizers may not be as effective against certain types of pathogens, including those that cause gastrointestinal infections. CHG (chlorhexidine gluconate) is commonly used as a surgical scrub or for disinfecting the skin, but it is not typically used for routine hand hygiene. Bleach is a strong disinfectant, but it is not meant for hand hygiene and can be harmful to the skin.

The given answer is true because according to Appendix D, all room/reusable equipment cleaning for patients on enteric and enhanced precautions must be done with bleach wipes or Oxicide.

The dry-time for different cleaning products, such as sani wipes or bleach wipes, can be found on the product container. The information regarding how long it takes for the product to dry after application is typically provided on the packaging itself. This allows users to know when it is safe to touch or use the surface that has been cleaned with the product.
