Infection Control & SafetyQuestion 68 of 100
Which link in the chain of infection is broken when a medical assistant performs proper hand hygiene between patients?
a.The infectious agent's ability to reproduce
b.The susceptible host's immune system
c.The mode of transmission
d.The portal of entry into the reservoir
Explanation
Hand hygiene interrupts the mode of transmission, because contaminated hands are the most common vehicle for carrying pathogens from one person to another. Handwashing does not change how an organism reproduces or strengthen the host's immunity. The reservoir has a portal of exit rather than a portal of entry, so that description misstates the chain.
