When the nurse performs a procedure using sterile technique in the patient's unit, it means that:
The equipment and supplies used are disposable and clean.
The nurse will be required to don a sterile gown, mask, and eye shields.
All organisms have been killed or removed from materials that come in contact with the patient.
The nurse will do a 10-minute surgical scrub before beginning the procedure.
The Correct Answer is C
Choice A rationale
While disposable and clean equipment reduce the risk of infection, sterile technique requires that all organisms are killed or removed from materials to achieve an aseptic environment.
Choice B rationale
Sterile gown, mask, and eye shields are required for surgical procedures, but not necessarily for all sterile techniques, such as catheter insertions or dressing changes.
Choice C rationale
Sterile technique ensures that all organisms are killed or removed, creating an aseptic field and preventing infection.
Choice D rationale
A 10-minute surgical scrub is part of pre-surgical preparation but is not required for all sterile procedures.

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.
Correct Answer is D
Explanation
Choice A rationale
A 45-year-old in traction for a fractured femur is at risk for infection due to immobility and potential surgical wounds, but not as high as someone with a Foley catheter.
Choice B rationale
A 56-year-old with pneumonia receiving oxygen is at risk for respiratory infections, but the presence of a Foley catheter significantly increases the risk of healthcare-associated infections.
Choice C rationale
A 70-year-old with congestive heart failure attached to a monitor has a risk of infection due to potential breaks in skin integrity, but not as high as someone with a Foley catheter.
Choice D rationale
A 65-year-old with a Foley catheter is at the highest risk for health care-associated infections because the catheter provides a direct pathway for pathogens into the urinary tract, increasing infection risk.
