A clients serum potassium level is 5.8, where is most of the potassium found? - inside the cell
A light gauze dressing may or may not be.... - applied to cover the burn area
After a burn why does plasma seep out into the tissue? - Increased capillary permeability (leaking)
Antimicrobial ointments can provide: - -antibacterial coverage
-promote a moist wound
Are amputations common with electrical burns? - -YES d/t poor circulation
-bc the circulatory system is destroyed (without adequate circulation in body parts they become
destroyed)
Broad Spectrum Antibiotics - -used until the wound cultures have returned
-make sure to collect cultures before starting the antibiotics
broad spectrum antibiotics are avoided because - -they could lead to super infections or
SECONDARY infections and even sepsis.
Carbon monoxide poisoning - -normally oxygen binds with hemoglobin
-carbon monoxide travels much faster than O2 (200xs faster) therefore it gets to hemoglobin first and
binds (oxygen cant bind now)
-client becomes hypoxic and tx is O2 at 100%.
Common Topical Drugs Used With Burns: - -mafenide acetate (Sulfamlylon)
-silver nitrate
-antimicrobial ointments

Debridement - Removal of foreign matter or dead tissue from a wound
Does eschar have to be removed? - YES. new tissue cannot regenerate if eschar is there.
Bacteria can also grow in eschar
Enzymatic debridement agents.... - used to remove necrotic, dead tissue
Grafting - -remove the burned dead tissue until healthy tissue is seen
-good skin is taken from a healthy donor site and place over the burned area
-the donor site is an open wound, so a transparent dressing is applied until bleeding stops
-Then the door site can be left open to air
-IF the client is well nourished, they can re-harvest from the same donor site q 12-14 day
-IF the skin graft should become blue or cool then that's a sign of poor circulation
-the PCP may take a tuberculin syringe and aspirate blood or exudate from under the graft
-The physician will sometimes order for roll sterile q tips over the graft with steady, gentle pressure from
the center of the graft out to the edge for proper adhesion
-Why? if air, blood, or excaudate is accumulating under the graft, the new graft will not adhere leading
to total or partial loss of the graft.
How do you apply topical agents to a burn? - Apply a thin layer of medication using sterile gloves
(sterile technique)
How long can silver dressings be left in place? - 3-14 days depending on the clients clinical
situation
