Competency For Covid-19 Swab Test

Proper hand hygiene should be observed before and after all contact with patients to prevent the spread of germs. It is also important to practice hand hygiene before and after contact with potentially infectious material to minimize the risk of contamination. Additionally, hand hygiene should be performed before putting on and after removing personal protective equipment (PPE) to ensure that any potential pathogens are eliminated. Therefore, all of the options mentioned in the question are instances where proper hand hygiene must be observed.

A positive pressure suit is not part of the basic personal protective equipment (PPE) to prevent the spread of COVID-19. PPE includes items such as gowns, disposable masks, and face shields, which are designed to provide a barrier between the wearer and potential sources of infection. A positive pressure suit, on the other hand, is a specialized form of PPE typically used in high-risk environments such as laboratories or hazardous material handling, where a positive pressure environment is needed to protect the wearer from external contaminants. It is not necessary for general COVID-19 prevention measures.

The condition that is NOT a contraindication for nasopharyngeal swabbing is a patient on aspirin. Nasopharyngeal swabbing is a procedure used to collect samples from the back of the nose and throat for testing. Recent nasal trauma, markedly deviated septum, and severe coagulopathy can all affect the safety and effectiveness of the procedure. However, being on aspirin does not pose a significant risk or contraindication for nasopharyngeal swabbing.

The correct sequence of doffing of PPE is gloves, face shield, gown, mask. This sequence ensures that the most contaminated items are removed first, minimizing the risk of contamination. Gloves are removed first to prevent any potential contamination on the hands from spreading. The face shield is then removed, followed by the gown, and finally the mask. Removing the mask last helps to prevent any potential aerosolized particles from being released into the air.

The statement "The top of a mask should be pinched snugly over the bridge of the nose" is true because it ensures a secure fit and helps to prevent any gaps or openings that could allow for the entry of contaminants. By pinching the mask over the bridge of the nose, it creates a seal and reduces the risk of inhaling or exhaling airborne particles. This is an important step in properly donning personal protective equipment (PPE) to ensure maximum protection against potential hazards.

The correct sequence for donning PPE is to first put on the gown, then the mask, followed by the face shield, and finally the gloves. This order ensures that the healthcare worker is properly protected from head to toe, with the gown covering the body, the mask covering the nose and mouth, the face shield protecting the eyes and face, and the gloves providing hand protection.

The correct sequence of hand washing is as follows: Palm to palm, Palm over the other, Fingers interlaced, Thumb over knuckles, Thumb clasped in palm, Wrist clasped in palm. This sequence ensures that all areas of the hands, including the palms, fingers, thumbs, and wrists, are thoroughly cleaned.

The oropharyngeal swab should contact the back of the throat and the tonsillar area. These areas are commonly swabbed to collect samples for testing purposes. The tongue and gums are not mentioned as areas that the swab should contact, so they are not included in the correct answer.

The ideal protocol for storage and transport of samples in transport tubes is to store the specimens at 12°C and ship them on an ice pack within 72 hours. This ensures that the samples are kept at a controlled temperature to maintain their integrity and prevent degradation. The use of an ice pack helps to maintain the required temperature during transportation.
