To offer an educational experience that will help to improve the participant's understanding of the various types of nonsurgical debridement.
This CME/CE activity is intended for physicians and nurses with an interest in the prevention, diagnosis, and treatment of chronic wounds.
At the conclusion of this activity, participants should be able to: 1. Describe the role of debridement in wound healing. 2. Identify the different types of nonsurgical debridement. 3. Summarize the benefits and limitations of the different types of nonsurgical debridement. 4. Identify wounds that should not be debrided.
1. Which of the following statements about debridement is true?
1. It is used to accelerate healing in a clean wound.
2. It should not be done prior to applying a bioengineered human skin equivalent.
3. It is indicated for removal of necrotic tissue, exudate, and waste from a wound.
4. It is not recommended for patients with osteomyelitis.
2. Which organism produces a fibrin-rich biofilm resistant to the body's natural immune response to foreign bodies?
2. Staphylococcus aureus
3. Debridement can be an important measure to
1. stop bleeding.
2. control wound infection.
3. decrease oxygen delivery at the wound site.
4. mask underlying collections of fluid or purulence.
4. A patient's wound has more than 50% necrotic tissue. Pulsed lavage for debridement might be performed
1. once a day for 10 to 20 minutes.
2. twice a day for 10 to 20 minutes.
3. once a day for 15 to 30 minutes.
4. twice a day for 15 to 30 minutes.
5. Which of the following statements about sharp debridement is true?

2. It is contraindicated in patients with cellulitis or sepsis.
3. It can be performed by any licensed health care professional.
4. It is performed with surgical instruments, such as scalpel, forceps, scissors, or laser, that are used to cut away dead tissue.
6. Which chemical debriding agent targets the collagen in necrotic wounds?
7. Which chemical debriding agent contains a proteolytic enzyme and a chemical to denature nonviable protein?
8. Which of the following statements about hydrocolloid dressings is true?
1. They are impermeable to oxygen, water, and vapor.
2. They are composed of proteolytic enzymes.
3. They need to be changed monthly.
4. They cause dehydration of the wound.
9. Which of the following statements about foam dressings is true?
1. They are made of biomaterials.
2. They promote tissue autolysis.
3. They provide excellent oxygenation at the wound surface.
4. They should be changed twice daily.
10. Eschar on stable heel ulcers may be left in place if
1. the eschar is firmly adherent to the surrounding tissue.
2. there is some indication of inflammation.
3. there is slight drainage from beneath the eschar.
