Internal mechanisms and external mechanisms
What do Standard Precautions do?
Incorporate the features of both body fluid precautions and body substance isolation
When do you use standard precautions?
When performing procedures that may require contact with:
-blood
-bodily fluids
-secretions
-excretions
-mucous membranes
-non-intact skin
What is the importance of standard precautions?
To practice bio safety in medical imaging
What are Transmission-Based precautions?
Employed in conjunction with standard precautions. Used on all patients with a pathogenic or communicable disease process.
What are the three common precautions?
- Airborne
- Droplet
- Contact
What does the term asepsis imply?
“Freedom from infection”
What are the two asepsis types?
-surgical asepsis
-medical asepsis
What are chemical methods of asepsis?
Disinfectants (bacteriostatic & bactericidal)
What are physical methods of asepsis?
Sterilization (autoclave)
What is sterilization?
The absolute killing of all life forms
What is the most effective method of sterilization?

Name examples of standard precautions
-handwashing
-gloving
-personal protective equipment (PPE)
-Needle recapping
-Bio spills
Hand washing absolutely must be performed _________ and _________ each patient is handled.
Before, after
What is the simplest method of environmental control of microbes?
