Example questions Flashcards
Why should bar soap not be used for handwashing?
Bars of soap may harbour and encourage the growth of microorganisms.
When are the 5 moments of handwashing, and why?
Immediately before each episode of direct patient contact or care, including clean/aseptic procedures; Immediately after each episode of direct patient contact or care; Immediately after contact with body fluids, mucous membranes and non-intact skin Immediately after other activities or contact with objects or equipment in the immediate patient environment that may result in the hands becoming contaminated; Immediately after the removal of gloves
Refers to points at which there is the greatest likelihood of transmitting potentially pathogenic microorganisms that may result in infection (the patient’s immediate environment)
When should soap and water be used for handwashing in preference to other types of hand decontamination (e.g. alcohol hand gel)?
Allows the mechanical removal of transient microorganisms; alcohol-based rub or gel is only effective when used on dry, visibly clean hands
Why are hands rubbed during hand washing?
To create friction; allows the mechanical removal of microorganisms
How can you prevent skin irritation as a result of hand decontamination?
Apply hand moisturiser regularly and see your occupational health department or general practitioner
When should gloves be worn?
Sterile gloves should be worn for any invasive procedure, where an aseptic technique is required, when the integrity of the skin is broken and when in contact with sterile sites.
Clean gloves should be worn when coming into contact with mucous membranes or broken skin, and for any activities that carry a risk of exposure to blood, body fluids, secretions or excretions, or with sharp or contaminated instruments.
Why would you carry out an aseptic procedure?
To ensure asepsis (absence of bacteria, viruses, and other microorganisms) and prevent the transfer of potentially pathogenic microorganisms to a susceptible site on the body, or to sterile equipment/devices.
What is required for an effective aseptic technique?
It requires strict application of guidance on hand hygiene and correct use of personal protective equipment.
What is the difference between a sterile and clean technique?
When using a sterile technique, the equipment, fluids and dressings used are sterile, whereas for a ‘clean technique’, clean but non-sterile single-use gloves are used with tap water (that is safe enough to drink) for cleansing.
