PCC2 Exam #2 Questions With Complete Solutions
types of debridement
Autolytic
Mechanical
Enzymatic
Sharp/Excisional
Biodebridement
autolytic debridement
The use of an occlusive dressing to allow endogenous enzymes
in the wound drainage under the dressing to debride necrotic
tissue
mechanical debridement
uses external physical force to dislodge and remove debris and
necrotic tissue
Wet to dry dressing
application of a moist dressing that is allowed to dry, removal of
the dry dressing debrides both necrotic and healthy tissue,
painful, non-selective and no longer an acceptable method of
debridement
wound scrubbing
Mechanical debridement using a sponge, brush, or gauze along
with a fluid to break the adherence of devitalized tissue and
debris from the wound bed.
,Hydrotherapy (whirlpool)
type of mechanical debridement
- concerns about cross contamination
Enzymatic debridement
the topical application of proteolytic enzymes to breakdown the
necrotic tissue
collagenase santyl (better on yellow/slough)
Papain and urea
Honey used in Europe but may cause further drying in wounds
that are dry - little standardization
sharp debridement
The use of a scalpel, forceps or scissors, or laser to remove dead
tissue
Performed by a physician or health professional with specialized
training per state practice acts
biodebridement
-Does not destroy healthy tissue
-Grown in sterile environment
-Inexpensive
-Bactericidal
-In place for 48-72 hours
Bacterial balance
, all wounds are contaminated but certain organisms are
especially virulent. They can multiply and invade the host,
causing systemic infection. This is more likely in immune
deficient patients
Classic signs of infected wounds
advanced erythema, fever, warmth, edema/swelling, pain,
purulence
Tuberculosis pneumonia
caused by tuberculosis, very serious lung infection and
extremely dangerous unless treated early
Pneumocystis carinii pneumonia (PCP)
PCP may be the first sign of illness in many persons with AIDS
ventilator acquired pneumonia
on the rise among patients endotracheal tubes for mechanical
ventilation
Pneumonia and your body
when the germs that cause pneumonia reach your lungs, the
alveoli become inflamed and fill up with fluid. This causes the
symptoms to pneumonia. Oxygen has trouble reaching the
blood. If there is too little oxygen in the blood, the body cells
can't work properly. Because of this and the infection spreading
through the body, pneumonia can cause death.
Pneumonia affects the lungs in two ways
