Jonas Goodstart has been a patient at Happy Valley Community Hospital for 5 days. During his stay in the hospital, he was taken to the diagnostic imaging department several times for diagnostic imaging procedures. He was cared for each time he went to that department by a radiographer who had a severe upper respiratory infection. Two days after he returned home from the hospital, he also developed a severe upper respiratory infection. It would be appropriate to say that Mr. Goodstart had developed:

A) An iatrogenic infection
B) A nosocomial infection
C) A community-acquired infection
D) A bloodborne infection

B) A nosocomial infection

10

Explain the difference between Tier 1 and Tier 2 infection control precautions.

Tier 1 - Standard precautions to prevent spread of infection are used daily for all persons cared for in all health care set-tings.

Tier 2 - transmission-based precautions, infectious diseases require radiographers and all health care workers to take additional precautions, as well as standard precautions to prevent infection of other health care workers, patients, other persons in the health care setting, and oneself. These precautions are designed to place a barrier to the spread of highly infectious diseases between persons with such diseases and the persons caring for them.
