Question 1

A nurse is about to remove a used IV cannula. Which PPE should she wear at minimum?

Accepted Answer

Non-sterile gloves

Answer

Removing a used IV cannula involves contact with blood/body fluids. Non-sterile (examination) gloves are the minimum requirement under standard precautions to protect from bloodborne pathogen exposure.

Question 2

What does 'decontamination' mean in healthcare settings?

Accepted Answer

The process of removing or destroying microorganisms from surfaces, equipment, or skin

Answer

Decontamination encompasses cleaning, disinfection, and sterilisation — the processes used to reduce or eliminate microorganisms from equipment and environments to safe levels.

Question 3

Which of the following is the correct order of donning (putting on) PPE?

Accepted Answer

Apron/gown → mask → gloves

Answer

The correct order of donning PPE is: apron/gown first (covers clothing), then mask (protects face), then gloves (the last item, protecting hands and covering gown cuffs). This sequence prevents contamination of PPE during application.

Question 4

What is the significance of a 'sharps injury' for a healthcare worker?

Accepted Answer

Risk of transmission of bloodborne viruses such as HIV, Hepatitis B, and Hepatitis C

Answer

Sharps injuries carry risk of bloodborne virus (BBV) transmission regardless of known patient infection status. Immediate first aid, reporting, and post-exposure prophylaxis (PEP) protocols must be followed.

Question 5

How should clinical waste (contaminated materials) be disposed of in an Irish hospital?

Accepted Answer

Yellow clinical waste bags for infectious waste, following local and national waste management guidelines

Answer

Infectious/clinical waste in Ireland is segregated into yellow clinical waste bags, collected by licensed contractors, and disposed of by incineration. Incorrect disposal is a legal and infection control violation.
