NUR 211- BURNS EXAM WITH 100%
CORRECT ANSWERS 2025
who is at high risk of mortality when burned? correct answers
>> the elderly and the very young, anyone with comorbidities,
anyone with inhalation injury or a TBSA of >50%
The skin is the largest organ in the body. What are its functions?
correct answers >> - protection against infection and injury
- regulation of fluid loss
- thermoregulation
- synthesis of Vitamin D
- sensation
- determination of identity
the 3 layers of the skin include? correct answers >>
Epidermis: the outermost and thinnest
Dermis: the functional unit of skin
Subcutaneous: binds the skin to tissues and insulates
you must have at least some of the ___________________ intact to
regenerate skin after burns correct answers >> dermis
people with deep partial thickness or full thickness burns will need
skin grafting
,Burns are classified into what 3 types? which is the most
common? correct answers >> thermal, chemical, and
electrical.
thermal (heat) is the most common, but chemical and electrical
require special initial treatment.
radiation from cancer treatments and the sun can also cause
burns
thermal (heat) injuries are caused when the skin comes into
contact with a source of sufficient temperature to cause cell injury
by? correct answers >> coagulation (direct burn to cells
turns a liquid to solid)
this can occur from flame, scalding liquids, steam, or a heat
source
The severity of a thermal injury is r/t the heat intensity and
duration of contact. A heat source of less than ___________ degrees
does *not* cause burns regardless of time of exposure correct
answers >> 104.
exposure of a temperature of *140* degrees can cause full
thickness burns in as little as 3-5 seconds
the average water heater in a home is set at 140 degrees.
, chemical injury is caused by? correct answers >> contact,
inhalation of fumes, ingestion, or injection of some type of
chemical substance
it can result in both local and systemic effects
*tissue damage will continue until the chemical is neutralized or
removed*
what is placed in the workplace and has information on all
chemicals in the building including composition, s/e, and potential
for toxicity? correct answers >> MSDS
what are the 3 categories of chemical agents? correct answers
>> 1. alkalis (these produce the worst burns)
2. acids
3. organic compounds
examples of alkalis include? correct answers >> bases like
lye, wet cement, fertilizer, and ammonia.
commonly found in the home
why do alkalis produce the worst burns? correct answers >> -
the skin cannot neutralize them bc they bind to tissue proteins
and make it more difficult to stop the burning process
