A nurse is educating a class of nursing students about Community Health in order to eliminate another pandemic. What organizations or facilities provide assistance with identifying community health care issues?

A. Utilizing a friend's computer keyboard: Indirect transmission occurs when pathogens are transmitted via inanimate objects, such as keyboards, doorknobs, or utensils. If the friend's computer keyboard is contaminated with pathogens, the patient could contract an illness by touching it.
B. Talking directly to someone coughing: This is an example of direct transmission, where pathogens are transmitted through close contact with an infected person's respiratory secretions.
C. Standing next to a person with a varicella (chickenpox) infection: This is an example of direct transmission, as varicella is spread through respiratory droplets.
D. Walking past an individual coughing and sneezing: This is also an example of direct transmission, as respiratory droplets containing pathogens can land on the nurse and lead to infection if inhaled or touched.

A. Povidone-iodine: Povidone-iodine is an antiseptic agent used for skin disinfection but is not recommended for routine hand hygiene, especially in cases of Clostridium difficile infection.

B. Alcohol-based antiseptic: While alcohol-based hand sanitizers are effective for most routine hand hygiene situations, they may not be sufficient for removing spores of Clostridium difficile. Soap and water are preferred for hand hygiene in cases of C. difficile infection.
C. Chlorhexidine: Chlorhexidine is an antiseptic agent commonly used for skin disinfection, but like alcohol-based hand sanitizers, it may not effectively remove C. difficile spores. Soap and water are preferred.

D. Soap and water: Soap and water are recommended for hand hygiene in cases of Clostridium difficile infection because mechanical friction from hand washing helps physically remove
spores from the hands.
