Wound Certification Exam Questions
and Answers 100% Solved
what are 6 risk factor components of Braden Scale for pressure ulcer? -
✔✔sensory perception, moisture, mobility, activity, nutrition, and
shear/friction
What is the name of the organization that developed the pressure ulcer
staging? - ✔✔NPUAP (national pressure ulcer advisory panel)
pathological effect of excessive pressure on soft tissue can be attributed by
3 factors? what are they? - ✔✔tissue tolerance, duration of pressure,
and intensity of pressure
what are the extrinsic factors that impact pressure ulcers? - ✔✔increase
in moisture, friction and shearing
how does friction play a role in shearing which eventually leads to pressure
ulcer? - ✔✔friction alone causes only superfical abrasion, but with
gravity it plays a synergistic effect leading to shearing. When gravity
pushes down on the body and resistance (friction) between the patient and

surface is exerted, shearing occurs. because skin does not freely move,
primary effect of shearing occurs at the deeper fascial level.
what are the intrisinc factors of pressur ulcers? - ✔✔nutritional
debilitation, advanced age, low BP, stress, smoking, elevated body
temperature
Aging skin undergoes what elements affecting risk for pressure ulcer? -
✔✔dermoepidermal junction flattens, less nutrient exchange occurs, less
resistance to shearing, changes in sensory perception, loss of dermal
thickness, increased vascular fragility; ability of soft tisuse to distribute
mechanical load w/out comprosing blood flow is impaired
What does nonblanching erythema indicate in the skin r/t PU? - ✔✔when
pressure is applied to the erythematic area skin becomes white (blanched),
but once relieved, erythema returns -indicating blood flow; however in
nonblanching erythema, skin does not blanche-indicating impaired blood
flow-suggesting tissue destructon
why does sitting in a chair pose more of a risk in skin break down than
lying? - ✔✔deep tissue injury or PU is likely to occur sooner sitting down
because tissue offloading over boney prominences is higher

Describe what you will see in deep tissue injury? - ✔✔purple or maroon
localized area of discolored intact skin skinor blood filled blister; may be
preceded by painful, firm, mushy, or boggy; skin may be warmer to cooler
in adjacent tissue. In dark skin, thin blister or eschar over a dark wound bed
may bee seen
Describe stage I pressure ulcer? - ✔✔Intact skin with nonblanchable
redness of localized area. Will not see blanching in dark skin, but changes
in skin tissue consistency (firm vs boggy when palpated), sensation (pain),
and warmer or cooler temperature may differ from surrounding area
Describe stage II pressure ulcer? - ✔✔partial-thickness wound where
epidermis and tip of dermis is lost with red-pink wound bed w/out slough.
may also present as intact or open/ruptured serum -filled blister
Describe stage III pressure ulcer? - ✔✔full-thickness wound where both
epidermis and dermis is lost and subcutaneous tissue may be visible, but
deeper structures such as muscle, bone, and tendon are not exposed;
slough my be present but it doesn't obscure depth and tunneling and
undermining may be present
Describe stage IV pressure ulcer? - ✔✔full-thickness wound with
exposed bone,tendon, and muscle; slough or eschar may be seen in some
, ©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
parts of the wound bed. you will often see tunneling and undermining.
Osteomyelitis may be dxed at this stage, since bone is palpable
Describe unstageble ulcers? - ✔✔full-thickness wound where base of
the ulcer is covered by slough and/or eschar, obscuring depth
When should eschars not be removed? - ✔✔when it's stable with dry,
adherent, and intact w/out erythema on the heel; this serves as the body's
natural cover and should not be removed.
Therapeutic function of pressure distribution is accomplised by what 2
factors? - ✔✔immersion and envelopement
Define immersion? - ✔✔depth of penetration or skining into surgace
allowing pressure to be spread out over surrounding area rather than
directly over boney prominence
Define envelopement? - ✔✔is the ability of support surface to conform to
irregularities without causing substantial increase in pressure
what is bottoming out? - ✔✔this occurs when depth of penetration or
sinking is excessive, allowing increased pressure to concentrate over
boney prominences
