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.

Answer and Explanation

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

Poor personal hygiene can contribute to infections but is not the primary cause of vaginal candidiasis. This condition is typically caused by an overgrowth of Candida albicans, which is not solely related to hygiene.

Choice B rationale

Unprotected sex is not a common cause of vaginal candidiasis. Candida albicans, the yeast responsible for this condition, is usually present in small amounts in the vagina and becomes problematic when it overgrows, which is not typically related to sexual activity.

Choice C rationale

Using bath oils may alter the vaginal flora but is not a primary cause of vaginal candidiasis. The condition results from an imbalance in the normal vaginal environment, often due to other factors such as antibiotics.

Choice D rationale

Long-term antimicrobial therapy is a common cause of vaginal candidiasis. Antibiotics can disrupt the natural balance of bacteria in the vagina, allowing Candida to overgrow and cause infection.

A. Kills all organisms. B. Uses sterile attire to protect the patient. C. Is confined to the patient's room. D. Uses sterile equipment before contact with the patient.

Correct Answer is D

Explanation

Choice A rationale

Medical asepsis does not kill all organisms; it reduces the number of pathogens to a safe level. Complete sterilization, which kills all organisms, is a characteristic of surgical asepsis.

Choice B rationale

Medical asepsis does not require the use of sterile attire to protect the patient. This is a practice associated with surgical asepsis to maintain a sterile field during surgical procedures.

Choice C rationale

Medical asepsis is not confined to the patient's room. It involves practices that reduce the risk of infection in various healthcare settings, not just in the patient's room.

Choice D rationale

Medical asepsis involves the use of sterile equipment before contact with the patient to reduce the risk of infection. This is a practice aimed at maintaining a clean environment and preventing the spread of pathogens. .
