A nurse is preparing a sterile field.
Which of the following actions should the nurse identify as contaminating the field?
Opening the sterile tray by first unfolding the flap furthest from his body.
Holding a sterile item at just above waist level.
Placing a sterile dressing 5 cm (2 in) from the border of the sterile field.
Opening a sterile package directly over the middle of the sterile field.
Opening a sterile package directly over the middle of the sterile field.
The Correct Answer is D
Choice A rationale
Opening the sterile tray by first unfolding the flap furthest from the body is a correct practice to avoid reaching over the sterile field, which helps maintain the sterility of the field.
Choice B rationale
Holding a sterile item just above waist level is appropriate as long as the item remains within the sterile field's boundaries. Keeping items at this level helps prevent accidental contamination from lower surfaces.
Choice C rationale
Placing a sterile dressing 5 cm (2 in) from the border of the sterile field is acceptable, as the border is considered non-sterile, and maintaining this distance helps ensure the sterility of the item within the field.
Choice D rationale
Opening a sterile package directly over the middle of the sterile field can lead to contamination. Any particles or contaminants from the package may fall into the sterile field, compromising its sterility. .

Correct Answer is D
Explanation
Choice A rationale
Filling linen bags with as much soiled linen as possible can cause the bags to be too heavy, increasing the risk of tearing and contamination. Overfilled bags are also harder to handle safely.
Choice B rationale
Returning unused fresh linen to the supply area can lead to contamination of clean supplies. It's recommended to avoid reusing linen that has been in a patient's room to maintain hygiene.
Choice C rationale
Double bagging is not a necessary practice for soiled linen unless the outside of the first bag becomes contaminated. It's more important to handle the bags properly.
Choice D rationale
Tying linen bags securely at the top helps to contain the soiled linens and prevents contamination and the spread of infections. Secure closure ensures that the contents remain contained during transport.
Correct Answer is A
Explanation
Choice A rationale
A 10% solution of chlorine bleach is an effective disinfectant for contaminated areas in the home. Chlorine bleach has broad-spectrum antimicrobial properties, making it suitable for killing various pathogens, including bacteria and viruses.
Choice B rationale
Soaking in a solution of povidone iodine for 30 minutes and rinsing with hot water is not practical for home disinfection. While povidone iodine is effective as a disinfectant, it is typically used for medical purposes and not for cleaning household surfaces.
Choice C rationale
A 12% solution of alcohol is not as effective as a 10% solution of chlorine bleach for disinfecting contaminated areas in the home. Alcohol concentrations above 70% are generally more effective for disinfection purposes.
Choice D rationale
Covering the area with boiling water and letting it air dry is not a reliable method for disinfecting contaminated areas. Boiling water may not effectively kill all pathogens, and this method lacks the broad-spectrum efficacy of chemical disinfectants.
