Wounds
| Question | Answer |
|---|---|
| Obesity is associated with increased risk of wound infection and dehiscence because | Decreased vascularization of fatty tissue leads to a decreased capacity for healing |
| is marked by fibroblasts and endothelial cells entering the wound | Proliferative phase |
| The , the first phase of wound healing, begins immediately | Inflammatory phase |
| drains are considered gravity dependent | Passive |
| A support bandage placed on a limb before a splint should be long enough to cover | The limb above and below the ends of the splint |
| The layer of a bandage, absorbs and holds exudate (if present) and provides some immobilization and support | Secondary |
| What is the best method to treat pressure sores caused by bandaging | Prevent them by using proper padding |
| Angiogenesis refers to | Formation of new blood vessels |
| Complete dehiscence of a thoracic wound will result in (air within the chest causing collapse of the lungs), a problem that may result in sudden death | Pneumothorax |
| When clipping hair from the edges of a skin wound to prepare it for primary closure, ______ should be placed over the wound | Water - soluble lubricant |
| Corticosteroids, especially with long-term use | All are correct |
| When lavaging a highly contaminated wound, tap water can be used initially instead of sterile isotonic fluids because the main benefit comes from | The volume rather than the type of fluid used |
| What must occur in order for a wound to be considered closed by primary closure | Closure must precede granulation tissue formation |
| migrate across healthy granulation tissue to reestablish a barrier between the wound and the environment | Epithelial cells |
| The inflammatory phase lasts for 3 to 5 days and is often called the lag phase because | Wound strength is at its lowest during this phase |
| Wounds can drain excessively, causing serum to seep through the bandage and extend to the external environment. This is called | Strike - through |
| What is the primary benefit of using a wet-to-dry bandage | To provide non-selective debridement |
| When monitoring distal limb bandages an increased distance between the toe nails indicates | Swelling |
| Passive drains provide a direct avenue for ascending infection and | Must have an exit that is in a dependent location |
| develop over bony prominences as the result of skin compression on hard surfaces during long periods of recumbancy | Decubitus ulcers |
| When applying a fiber glass cast the water, the faster the curing process of the resin, resulting in premature hardening of the fiberglass cast materia | The warmer |
| For optimal effectiveness in immobilization, a cast must immobilize | The joint proximal and distal to the injury |
| Open wounds on the distal aspect of the limb (below the carpus or tarsus) of the horse are notorious for developing exuberant granulation tissue, commonly referred to as | Proud flesh |
| It is imperative to use a(n) primary layer once granulation tissue has formed or epithelialization has begun, to protect and promote second intention wound healing | Non - adherent |
| Which of the following is true regarding bite wounds | They often require the use of drains in their treatment |
| Which of the following wounds are most predictable in their healing pattern | Incision from a mass removal |
| Drains are generally removed when | Fluid production has slowed or ceased |
| If fluid strike-through of the tertiary layer of a bandage occurs | Bacteria from the environment can penetrate the bandage and contaminate the wound |
| -degree burns are full-thickness injuries characterized by a thick, leathery, often black layer of dead dermis | Third |
| Why is honey employed in wound management | It has antimicrobial effects |
| Healthy granulation tissue is in appearance | Pink |
| Newly epithelialized wounds | Are friable |
| The goal of is removal of obviously contaminated, devitalized, or necrotic tissue and elimination of foreign debris from the wound | Debridement |
| Fibroblasts deposit into the wound, which increases wound strength | Collagen |
| Passive drains are left in place for how long before removal and skin closure | 3 to 5 days |
| Once a wound heals, the wound tissue will be | Weaker than the original tissue |
