A nurse is providing care to a client who has Salmonella food poisoning. The nurse understands that this pathogen was transmitted by which mechanism?
A) Direct contact
B) Vehicle
C) Droplet
D) Airborne
Ans: B
Feedback:
Vehicle transmission involves the transfer of microorganisms by way of vehicles or contaminated items that transmit pathogens; for example, food can carry Salmonella. Direct contact transmission involves body surface-to-body surface contact causing the physical transfer of organisms between an infected or colonized person and an infected host. Droplet transmission occurs when mucous membranes of the nose, mouth, or conjunctiva are exposed to secretions of an infected person who is coughing, sneezing, or talking. Airborne transmission occurs when fine particles are suspended in the air for a long time or when dust particles contain pathogens.
