The client has a heavily draining wound for which there is an order to change the dressing every 4 hours. The nurse becomes busy and does not change the dressing as ordered. Which link in the chain of infection has the nurse allowed to flourish?
A) Susceptible host
B) Portal of exit
C) Reservoir
D) Mode of transmission
Ans: C
The reservoir is the area where a pathogen grows and reproduces. Leaving the dressing unchanged allows for a dark, warm, nutrient rich, and moist environment where many organisms will thrive. A susceptible host is a person who cannot fight off an infection. The portal of exit is the way a pathogen exits the host. The mode of transmission is the way the pathogen travels.
