What does the term asepsis mean?
The absence of potentially pathogenic organisms
What is aseptic technique?
A set of practices and procedures which ensures asepsis and for preventing the transfer of potentially pathogenic microorganisms to a susceptible site on the body or sterile equipment.

false
What kind of environment should you ideally dress a wound in?

A clean technique is a modified aseptic technique which aims to avoid introducing microorganisms to a susceptible site and also to prevent cross-infection to patients and staff”. Is this statement true or false?
True

Remove and dispose of your gloves, then decontaminate your hands
Which of the following factors support the use of an aseptic technique as opposed to a clean technique?

- other people
What are transient microorganisms?
Microorgnisms found on the skin
How does hand hygiene reduce the risk of HCAIs?
It breaks the chain of infection
What does HCAIs stand for?
Healthcare-associated infections.
According to NPSA failiure to carry put thorough hand hygiene may result in HCAIs in what way?
- Transfering the paties’s own microorganism from normal sit into sterile parts of patients body during care delivery or treatment
- transferring microorg. from patient to patient (cross-infection)
- transferring microorg. from environment/equipment to patient
True/False HCAIs can occur only in the hospital
False, HCAIs can occur in any setting where healthcare is delivered, even at homes.

clothing which is bear below the elbows.

- Removes clostridium difficile and norovirus
When should you use hand washing over alcohol gel
- When hand s are visibly soiled
- Caring for patients with vomiting or diarrhoeal illness
- After using toilet
- Before Handling food.
Why should healthcare staff not use bars of soap for hand washing?
They can harbour and encourage growth of microorganisms.
Which is more effective hand washing or alcohol gel rub?
Alcohol gel rub
What Hand hygiene technique should be used on visibly soiled hands?
Hand washing, Alcohol gel rub is ineffective against organic soiling

- Hand washing
- Alcohol rub is ineffective against Clostridium difficile, norovirus and other diarrhoeal infections
What is a commonly reported skin problem when using antiseptic agents (i.e. containing idine, chlorhexidine)?
Dermatitis
Why should you not use antiseptic agents (i.e. contaiining iodine) for routine use in had hygiene?
Increased risk of dermatitis and irritated skin
Are nailbrushes recommended for routine hand hygiene?
No, because they can act as a vector for transferrimg microorganisms from one person to another.
Single use nailbrushes are essential for surgical scrubbing.
Suggest ways in which you can limit the damaging effect of hand washing
- Wet hands before applying soap.
- Pat hands with paper towels rather than rub.
- Use hand emollients regularly
Which areas are most frequently missed when hand washing?
The back of the thumbs,
Between fingers
fingertips and nails
in the grooves of the hand
What is the purpose of “standard precations” with regards to using protective equipment?
To reduce the risk of ransmission of microorganism from one person to another.
True/ False practitioners should keep their gloves in their pockets?
False, as this increases risk of contamination.
Prior to any procedure, what should practitioners before carrying out hand hygiene and putting on gloves?
Ensure equipment is all ready thus gloved hands remain as clean as possible
When must sterile gloves be worn?
For any invasive procedure where an aseptic technique is required when the integrity of the skin is broken. Also for contact with sterile sites.
Give examples for when sterile gloves should be used
- Surgical procedures
- Suturing
- Cathterisation
- Vaginal Examination during labour, following rupture of membrane
- Bladder Irrigation
- Invasive investigations i.e. bone marrow biopsy, lumbar punctures.
When coming into contact with mucous membranes broken skin or any procedure which causes exposure body fluids, what type of gloves should be worn?
