WoundSource Practice Accelerator: Biofilms and Wound Care
Test your knowledge based on your learning from the materials provided in the WoundSource Practice Accelerator program on Biofilms and Wound Care.
1. Biofilms are found not only in wounds, but on medical devices such as prosthetic heart valves, orthopedic implants, intravascular catheters, and artificial hearts. *
1 point
2. Examples of biofilm include those adhered to rocks at the bottom of a stream, on the floors of showers and in sewage pipes, sometimes causing blockage and corrosion. Teeth with dental plaque also have biofilm, which can lead to the development of tooth decay and gum disease. *
1 point
3. Biofilm formation contributes to chronic inflammation, delayed healing and eschar formation. *
1 point
4. Biofilm is present over 60%-90% of chronic wounds and 6% of acute wounds. *
1 point
5. Biofilm life cycle has four parts: attachment, growth, maturation and detachment. *
1 point
6. Biofilm cannot become biocide tolerant within 12 hours. *
1 point
7. If disrupted or disturbed, biofilm can entirely reform in 24 hours. *
1 point
8. At least one-third of all chronic non-healing wounds contain biofilm. *
1 point
9. Biofilms are not resistant to biocides. *
1 point
10. Every species of microorganism is capable of making biofilms. *
1 point
11. Studies show that as many as 300 different species of bacterial can inhabit biofilm in dental plaque. *
1 point
12. Visually, biofilm is ____ and _____ due to the extracellular polymeric substance, and has a tenacious attachment to the wound bed. (Fill in the blank). *
1 point
Required
13. How many pounds per square inch (psi) of pressure are recommended for debridement in order to adequately clean the wound bed yet protect fragile granulation tissue? *
1 point
14. The importance of debridement is to remove biofilm, necrotic tissue, senescent or aberrant cells, all of which may harbor bacteria, increase the risk of infection, delay the healing process, impair macrophage function and physically splint the wound open. *
1 point
15.The Levine Quantitative Swab Technique for culturing a wound includes cleansing the wound with the following (select one). *
