Webinar: Wound Healing 101 with Dr. Ian Sandler, DVM Question Title * 1. Please fill in your personal information: First Name: Last Name: Email Address: Occupation: Veterinary Practice/Clinic Province Question Title * 2. For wounds to heal they need to go through a four-stage process. The four stages are; hemostasis, inflammation, proliferation, maturation True False Question Title * 3. What is the stage of the healing process where restorative cells such as macrophages and neutrophils are released into the wound site, causing the ‘redness’ and ‘warmth’ associated with healing? Hemostasis Inflammation Proliferation Maturation Question Title * 4. Healing can occur with or without the inflammatory response. True False Question Title * 5. How many times faster does a wound heal in a moist environment compared to a wound left out to dry? same healing rate 50% faster 10% faster 25% faster Question Title * 6. [Blank] will occur If the wound and surrounding skin is too wet which will cause skin breakdown. If the wound is too dry, the wound becomes [blank] and healing is delayed. Maceration, desiccated Proliferation, necrotic Maceration, necrotic Bacteria, purulent Question Title * 7. What is produced as a natural response to injury and plays an important role to healing? Wound fluid and Exudate Secretions and Slough Question Title * 8. Even if necrotic tissue delays healing it does not serve as a risk for inflammation and infection True False Question Title * 9. Wound fluid or exudate has an important role to play in healing, what does it do? Brings tissue-repairing cells, MMPs and growth factors to the wound Hydrates the wound bed preventing it from drying out Helps to wash away debris and devitalized tissue All of the above Question Title * 10. What amount of exudate will stop epithelialization and delay healing? Too much exudate Too little exudate Question Title * 11. What colour can we expect in a healthy exudate? It is generally clear, pale amber and watery It is generally pale amber, watery and can have traces of blood It is generally yellowish and watery It is generally white and semi-watery Question Title * 12. Which type of debridement uses a dressing to create a moist wound environment to enhance the ability of the body's own enzymes to shed necrotic tissue? Autolytic debridement Surgical debridement Mechanical debridement Question Title * 13. The Epidermis of the skin contains many important cells including; Keratinocytes Melanocytes Langerhans cells Merkel cells All the above Question Title * 14. In animals, sebaceous glands are present in large numbers near the paws, back of the neck, rump, chin, and tail areas. True False Question Title * 15. Mechanical wet-to-dry dressings are not ideal because they: Cause pain when removed Remove healthy and dead tissue Disrupt epithelialization Delay healing All the above Question Title * 16. The empirical use of antibiotics is warranted if a wound is not infected. True False Question Title * 17. It is important to debride healthy granulation tissue. True False Question Title * 18. Local hypothermia increases the risk of infection because: It causes vasoconstriction and decreases availability of oxygen to the phagocytes (cells ingesting bacteria or other dead cells) It causes vasodilation and increases availability of oxygen to the phagocytes (cells ingesting bacteria or other dead cells) Question Title * 19. Wound healing is accelerated when the wound bed is kept warm at body temperature True False Question Title * 20. Moist wound healing provides increased protection of the wound and surrounding skin. This provides advantages to a wide variety of wounds, including: Abscesses Cyst/lipoma removal Tumor removal Abdominal surgeries with leakage Surgical incisions Traumatic wounds All the above Question Title * 21. Utilizing dressings that ensure a moist wound environment will: Deliver faster healing times with less infections Require less bandage changes Minimize pain and discomfort for the patient Decrease the need for sedation during bandage changes Increase compliance All the above Done
