Choice B rationale

Standard Precautions do help prevent the transmission of respiratory and wound infections, but their application is universal, not limited to these conditions.

Choice C rationale

Standard Precautions are designed to be used when caring for all patients, regardless of their diagnosis or infection status, to prevent the spread of infections.

Correct Answer is B

Explanation

Choice A rationale

Vectors are living organisms, such as mosquitoes, that transmit pathogens between humans or from animals to humans. An inanimate object like a glass is not a vector.

Choice B rationale

Fomites are inanimate objects that can carry and transmit pathogens, such as a glass, door handles, or medical instruments.

Choice C rationale

Prions are infectious proteins that cause neurodegenerative diseases, not inanimate objects that transmit infection.

Choice D rationale

Interferons are proteins produced by cells in response to viral infections and do not relate to the transmission of pathogens via inanimate objects. .

A. Is complicated and hard to follow. B. Is that new diseases have continued to appear for which the older isolation techniques were ineffective. C. Is based on newer knowledge of how HIV is spread, to better protect health care workers from blood-borne pathogens. D. Is based on the premise in the new procedures that all body substances except sweat may be infectious, even when the person is not known to have a specific disease.

Correct Answer is D

Explanation

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.
