Answer 2

Open wound
Surgical injections
puncture site
Insertion site

Question 3

What are the key parts outlined in the key-part key-site protection?

Answer 3

Critical parts of procedure equipment that come into contact with active key parts connected to the patient, any liquid infusions or key sites.

For example: The tip of a syringe, needles, the wound side of addressing, intravenous ports or catheters

Question 4

When are standard ANTT’s used?

Answer 4

Used for technically uncomplicated invasive procedures that involve minimal key parts and small key sites.
Short in duration (approx under 20 mins)

Question 5

Answer 5

1) Cannulation
2) Reconstituting and administering certain medication
3) Venepuncture

Answer 6

Used for technically complicated invasive procedures that involve large or numerous key parts or key sites, significantly invasive or will take longer than 20 minutes to complete

Question 7

Give examples of surgical ANTT

Answer 7

• surgical wound dressing
• any procedure involving incisions through skin
• placement of central venous line

Question 8

For the ANTT risk assessment what do you have to consider the risks posed by?

Answer 8

The procedure environment, procedure invasiveness, the number and size of key parts and sides, operator competency, procedure duration

Question 9

What do you do to decide between standard and surgical ANTT?

Answer 9

Consider the risks as outlined in the a NTT risk assessment and then asked to maintain the sepsis of key parts and key sites does the main aseptic field require critical management?
If no then use standard ANTT
If yes then use surgical ANTT

Question 10

What are the components required for a successful standard ANTT?

Answer 10

• General aseptic field
• Micro critical aseptic fields
• non-touch technique
• hand cleansing
• infective precautions

Question 11

What are the components required for a successful surgical ANTT?

Answer 11

• critical aseptic field
• critical aseptic field management
• surgical hand scrub
• MCAFs and NTT desirable
• Infectjve precautions

Question 12

When should you use sterilised gloves?

Answer 12

Surgical ANTT: always
Standard ANTT: (if key parts and key sites don’t touch) non-steralised gloves
Standard ANTT: (if key parts and key sites do touch) sterilised gloves
