Care for Patients with Burns
| Question | Answer |
|---|---|
| T or F: the very young and the very old are extremely susceptible to burns. | T |
| _____ is the largest organ of the body. It's responsible for ______, ______, ______, and _______. | skin; protection, excretory, sensory, heat regulation |
| T or F: skin also provides our unique identity. It has an aesthetic function and a burn on the face affects the pt both physically and psychologically due to altered body image. | T |
| Skin is the ______ line of defense. It's our body's barrier and ____ can damage it causing us to become prone to infection. | first; burns |
| Skin also maintains ______ balance and burns can disrupt this balance due to ______ caused by ______. We lose 4x the amount of fluid compared to perspiration. | fluid-electrolyte; fluid loss; evaporation |
| T or F: burns CAN'T vary from a sunburn (1st degree) to a burn that involves all layers of our skin (3rd degree). | F |
| T or F: all burns are painful even when nerve endings are dead b/c the surrounding tissue is still uncomfortable. | T |
| Skin is responsible for ______ when exposed to sunlight. During a _____ burn, the activation is reduced due to skin loss. During a _____ burn, there is no activation at all. | vitamin D activation; partial thickness; full thickness |
| The rate at which heat is loss is dependent upon the _____ of our skin. The temperature depends on the _________ through the skin. | temperature; rate of blood flow |
| 1. When a pt experiences a burn, _____ triggers intense inflammatory response and triggers the immune system. | thermal injury |
| 2. _____ will then occur wherein blood vessels will _____ to compensate for blood loss. Then ______ will form and healing cells will rush then _____ are released. | vasoconstriction; constrict; clots; histamines |
| 3. Initial release of _____ will result to an inflammatory response. | histamines and/or bradikynin |
| 4. The inflammatory response will then ____________, wherein whatever's inside the cell leaks out from the intravascular space to the interstitial space. This shift leads to a condition called _________. | increase capillary permeability; 3rd spacing |
| 5. ______ will cause plasma to continue to leak along with Albumin (protein). | 3rd spacing |
| T or F: 3rd spacing could lead to edema (accumulation of tissue between tissue spaces) and the PCP will order diuretics to excrete fluid. | T |
| 6. 3rd spacing will lead to _____ and _____. Pt could then become hyponatremic. | fluid loss, sodium depletion |
| 7. ______ will occur causing further leaking of fluid into the interstitial spaces. Pt continues to lose plasma and protein which ______ blood volume and _____ BP. | vasodilation; decreased; decreased |
| 8. Pt becomes hypovolemic and loses HCO3 leading to ______ (b/c H+ is in greater amount) and ______ (due to K+ being pushed out of the cell and disruption also causes it to leak to the systemic circulation). | metabolic acidosis; hyperkalemia |
| Fluid shift occurs from _____ to _____ hrs. And _____ to _____ hrs is a critical time b/c there are profound imbalances in our fluid, electrolytes, and acid-base during this time. | 12-36; 24-36 |
| A minor burn affects ______ of the surface area. A moderate burn affects _____. And a major burn affects ______. | <10%, 12-25%, >25% |
| Burns are classified by 3 things: ______, _____, and _____. | depth, % of body surface, organs affected |
| _____ is used to treat minor burns <25% TBSA. | Bacitracin |
| ________ is used for 2nd or 3rd degree burns >25% TBSA. It's bacteriocidal. | Silvadene |
| ______ is used to treat >25% TBSA with fungal infections and is for pts with sulfur allergy. | Silver Nitrate |
| _______ is used to treat electrical injury and wounds resistant to other topical agents. | Sulfamylon |
| T or F: for nutritional support, pt should have a positive nitrogen balance, early nutrition, maintain body protein, and maintain daily calorie intake. This is critical b/c burn pts go through a ______. | T; hyper state |
| If the pt is _____, then they're not getting adequate nutrition. So always do daily weights. | losing weight |
