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 B
Explanation
Choice A rationale
Limiting ambulation can increase the risk of complications such as deep vein thrombosis and does not necessarily reduce HAIs.
Choice B rationale
Encouraging the patient to turn, cough, and deep breathe every 2 hours helps prevent respiratory complications, improves lung function, and reduces the risk of pneumonia, a common HAI.
Choice C rationale
Keeping the room door closed does not prevent HAIs and might isolate the patient, reducing mobility and social interaction.
Choice D rationale
Regular monitoring of vital signs is essential but does not directly reduce the risk of HAIs. Other measures, like proper hygiene and mobilization, are more effective.
Correct Answer is C
Explanation
Choice A rationale
While a scrub time of 7 minutes can be effective, it exceeds the necessary average time and may cause skin irritation with prolonged scrubbing.
Choice B rationale
A 6-minute scrub is also effective but similarly exceeds the average time, which is typically shorter to balance effectiveness and skin health.
Choice C rationale
A 5-minute scrub is the standard average time, balancing thoroughness in removing transient microorganisms with skin integrity.
Choice D rationale
A 3-minute scrub is often considered too short to ensure adequate removal of microorganisms, potentially compromising aseptic technique.
