Lesson 10 (Part 1) Flashcards
What is recommended for invasive procedures?
That sterile gel is used
When do you most often use bacteriostatic gel?
When the skin mucous membrane is intact
How often should the gel warmers be cleaned? (2)
- Weekly
- with low level disinfectant - Immediately
- if the warmer becomes soiled
How is the gel placed on the patient?
By indirect means
- no contact of the bottle to the patient
- not on the transducer (patient safety)
What are negative effects of placing the gel directly on the transducer? (3)
- Could contaminate the bottle and it would need to be discarded
- Could miss and spill on the floor
- Could touch contact and be an increase in transmission
What is gel mostly made up of?
Water
Why are intra cavity cleaning procedures important? (2)
- To keep the sonographer safe from exposure to any blood or body fluids
- To protect the patient from cross contamination from any instruments used for the procedure
What is the most important PPE for intra cavity procedures?
Gloves
- a gown can be work if needed
HLD
High level disinfection
What happens to all intra cavity probes?
They are all put though a process of HLD
What do you do to the intra cavity probe before HDL? (2)
- Wash it
- rinse with water - Thoroughly/visually inspect it
What must the probe be before it goes through HLD? (2)
- Clean
2. Dry
What kind of room is cleaning and HLD performed in?
Dirty room
What is the cleaning room equipped with? (3)
- Sink
- Eye washing station
- Any cleaning agents required
Where is the automated HDL kept? (2)
- In the cleaning room
2. Examination room
What are the most common invasive procedures using ultrasound? (2)
- Biopsies
- Aspirations
- guide a needle to remove fluid
What is low level disinfection used for?
Noncritical items that come in contact with intact skin
What are examples of noncritical patient care items? (2)
- Bedpans
2. Blood pressure cuffs
What are examples of noncritical environmental surfaces? (3)
- Bed rails
- sometimes can be intermediate level disinfection (patient circumstances) - Food utensils
- Bedside furniture
What is intermediate level disinfection used for?
Noncritical items that may come in contact with non-intact skin
- but for a brief period of time
What are intermediate level disinfectants?
They are chemical agents that do not kill bacterial spores but are tuberculocidal and kill other disease producing microbes
What are HLD used for?
Semi critical items that come in contact with mucous membranes or non intact skin
What are examples of things that require HLD? (4)
- Anaesthesia equipment
- Endoscopes
- Cystoscopes
- Ultrasound probes for certain exams
- intra cavity
What must be considered after extended use with the item to be disinfected for patient care?
The chemical compatibility
What is sterilization used for?
Critical items with high risk for infection if contaminated with microorganisms
What are examples of critical items that need sterilization? (3)
- Surgeries
- Cardiac and urinary catheters
- Biopsies
- any invasive procedures
Who can perform sterilization? (2)
- Nurses
2. Operative staff in a clinic setting where there are operative procedures done
Where does sterilization happen in a large organization?
There is a central processing department usually responsible for this process
- due to high volumes of instruments and to ensure consistency
Steam sterilization
Saturates the item with steam under high pressure
Why is steam sterilization not used on some instruments? (2)
- Corrosion
- Reduced ability to transmit light
- such as a laryngoscope
What is a benefit to steam sterilization?
It makes it even hotter which is harder to bacteria to survive
