A nurse is instructing a nursing student about principles of aseptic technique. The nurse would recognize the need for further instruction if the nursing student states, "I must:

Keep my sterile gloved hands in sight, away from all unsterile objects.”.

Open the wrapper of a sterile pack toward my body, the proximal flap first.”.

Avoid coughing sneezing, or unnecessary talking near or over a sterile field.”.

Avoid reaching across or above a sterile field with my bare hands or arms.”.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Keeping sterile gloved hands in sight, away from unsterile objects, maintains sterility by reducing the risk of accidental contamination.

Choice B rationale

Opening the wrapper of a sterile pack toward the body, starting with the proximal flap, increases the risk of contaminating the contents of the sterile pack, as the wrapper may touch unsterile clothing.

Choice C rationale

Avoiding coughing, sneezing, or talking near a sterile field is essential as respiratory droplets can introduce contaminants and compromise the sterility.

Choice D rationale

Avoiding reaching across or above a sterile field with bare hands or arms prevents contamination from skin cells or clothing particles that might fall into the field.

Correct Answer is D

Explanation

Choice A rationale

Lowering a used mask below the chin to reuse it later is not safe as it can lead to contamination of the mask and facial area, increasing the risk of infection.

Choice B rationale

Removing the mask first before any other personal protective equipment (PPE) can lead to contamination and is not the recommended sequence for doffing PPE.

Choice C rationale

Discarding the mask only if it is wet and storing it for reuse is not safe. Masks should not be reused, as they can harbor infectious agents and increase the risk of contamination.

Choice D rationale

Untying the bottom ties first, then the top, and disposing of the mask without touching it ensures that the person removing the mask avoids contamination. This method adheres to proper doffing procedures and minimizes the risk of infection.

A. Using disposable gloves after hand hygiene when feeding the infant. B. Keeping fingernails short and avoiding wearing rings. C. Washing hands up to the elbows for 2 minutes the first time in the day, and for 1 minute after a diaper change. D. Home care requires less attention to medical asepsis, so hand hygiene is necessary only after toileting or handling soiled diapers.

Correct Answer is B

Explanation

Choice A rationale

While disposable gloves can reduce the transmission of pathogens, they should not replace proper hand hygiene. Gloves should be used when handling bodily fluids or when contact with infectious materials is likely, not necessarily for feeding an infant.

Choice B rationale

Keeping fingernails short and avoiding rings reduces the risk of harboring pathogens under nails and jewelry, which can be difficult to clean properly. This measure helps prevent the transmission of infections.

Choice C rationale

Washing hands up to the elbows is not necessary for routine home care and can cause skin irritation. Hand washing should focus on the hands and wrists, and the duration should be at least 20 seconds.

Choice D rationale

Home care still requires strict attention to medical asepsis, especially when caring for infants. Hand hygiene is necessary not only after toileting or handling soiled diapers but also before and after preparing food, feeding, and other activities.
