Question 1

At Alderley Lodge, a staff member washes their hands between completing one task and beginning the next. Which link in the chain of infection is primarily broken by this action?

Accepted Answer

The mode of transmission, because hands are how the organism would have travelled from one place to the next.

Answer

The reservoir, because the organism no longer has anywhere to live.

Answer

The susceptible host, because the next person becomes harder to infect.

Answer

The portal of entry, because the organism can no longer get in.

Question 2

At Marchmont Laboratory, a technician is comparing different decontamination methods. What is the primary difference between sterilisation and disinfection in this setting?

Accepted Answer

Sterilisation removes or destroys all microorganisms including spores, while disinfection reduces them to a level considered safe.

Answer

Sterilisation uses chemicals and disinfection uses heat.

Answer

They mean the same thing, and the choice of word is a matter of habit.

Answer

Sterilisation is used on surfaces and disinfection on instruments.

Question 3

At Marchmont Laboratory, a worker must clean an instrument before it is disinfected. Why is the removal of visible soil essential before the disinfection process begins?

Accepted Answer

Because organic matter shields microorganisms from the disinfectant, so the process cannot work as intended.

Answer

Because the disinfectant would otherwise be wasted.

Answer

Because cleaning alone is enough to make the instrument safe.

Answer

Because the instrument would otherwise be difficult to handle.

Question 4

A worker at Alderley Lodge has just finished a task and removed their protective gloves. What is the correct next step for the worker to take?

Answer

Nothing, because the gloves were the protection.

Hands should be cleaned only if the gloves were visibly damaged.
