A nurse who uses meticulous sterile technique when performing wound care procedures is attempting to control which link in the chain of infection?
Reservoir
Portal of entry
Characteristics of the organism
Portal of exit
The Correct Answer is B
A. The reservoir is the source of infectious agents, not the method by which they enter the body.
B. Meticulous sterile technique during wound care procedures helps prevent microorganisms from entering the body, thereby controlling the portal of entry for potential pathogens.
C. Characteristics of the organism refer to factors such as virulence and pathogenicity, which influence the organism's ability to cause infection but are not directly controlled by sterile technique during wound care.
D. The portal of exit is the route by which infectious agents leave the reservoir, such as through respiratory secretions or bodily fluids, and is not directly controlled by sterile technique during wound care.
