2. An infectious agent or pathogen
3. A susceptible host
4. A reservoir or source for pathogen growth
5. A portal of entry to a host
6. A portal of exit from the reservoir
a. 3, 2, 4, 1, 5, 6
b. 1, 3, 5, 4, 6, 2
c. 4, 2, 1, 6, 3, 5
d. 2, 4, 6, 1, 5, 3

For spread of infection, the chain has to be uninterrupted with an infectious agent, a reservoir and
portal of exit, a mode of transmission, a portal of entry, and a susceptible host. The nurse manager is
evaluating the chain of infection to determine actions that could be implemented to influence the
spread of infection in the intensive care unit. Understanding the spread of infection and directing
actions toward those steps have the potential to decrease infection in the setting.
