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.”.
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
Throwing the needle and syringe immediately into a covered garbage can with a red plastic liner is not the safest disposal method for biohazard materials. It does not prevent needle stick injuries effectively.
Choice B rationale
Recapping the needle and placing it on the patient's table until leaving the room is not a safe practice. It increases the risk of needle stick injuries and potential exposure to contaminated materials.
Choice C rationale
Breaking the needle from the syringe using the needle cover to prevent reuse does not ensure complete safety. It can still lead to needle stick injuries and improper handling of biohazard materials.
Choice D rationale
Never recapping the needle afterward is the safest approach. It minimizes the risk of needle stick injuries and ensures proper disposal in designated sharps containers immediately after use.
Correct Answer is D
Explanation
Choice A rationale
Disinfectants are not intended for use on the patient's body. Using them around the eyes or mouth can cause irritation or harm, as they are designed to kill or inhibit the growth of microorganisms on inanimate objects.
Choice B rationale
It is important to thoroughly clean and rinse all soap off equipment before disinfecting, as organic matter and soap residues can interfere with the disinfectant's effectiveness. Proper cleaning removes debris that can protect microorganisms from the disinfectant.
Choice C rationale
Disinfectants cannot sterilize instruments as sterilization refers to the complete elimination of all forms of microbial life, including spores. Bacteriostatic disinfectants only inhibit bacterial growth and do not achieve sterilization.
Choice D rationale
Removing organic matter prior to disinfecting is crucial because organic material can protect microorganisms from the disinfectant, reducing its effectiveness. Proper cleaning ensures that the disinfectant can directly contact and eliminate the microorganisms.
