Reservoir

Portal of entry

Characteristics of the organism

Portal of exit

Answer and Explanation

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.
