Choice A rationale

The new procedures are designed to be more comprehensive and inclusive of a range of pathogens. They are not necessarily more complicated or hard to follow but aim to cover all potential sources of infection.

Choice B rationale

While it is true that new diseases have appeared, the main reason for the new procedures is to address the broader range of infectious agents, not just new diseases.

Choice C rationale

The new procedures are designed to protect against all types of infections, not just HIV. They emphasize the need for precautions with all body substances.

Choice D rationale

The new procedures are based on the premise that all body substances except sweat may be infectious, which requires healthcare workers to take precautions with all body fluids, regardless of the known infection status of the patient.

Correct Answer is C

Explanation

Choice A rationale

Washing hands for 10 seconds is insufficient for effectively removing germs and contaminants from the skin.

Choice B rationale

Washing hands for 1 minute ensures thorough cleaning but might be longer than necessary for routine hand hygiene in many healthcare settings.

Choice C rationale

Washing hands for 2 minutes is recommended at the beginning of a shift to ensure comprehensive removal of any contaminants present on the hands.

Choice D rationale

Washing hands for 15 seconds is more suitable for routine handwashing but not for the initial handwashing at the beginning of the shift, which requires more thorough cleaning. .

A. Decrease organisms on the patient's body but take care not to use it around the patient's eyes or in the mouth. B. Thoroughly clean and rinse all soap off the equipment before disinfecting it. C. Sterilize instruments with a bacteriostatic disinfectant. D. First remove all organic matter prior to disinfecting.

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.
