WTA C Exam – 2025–2026 – Practice Test with Answer
Key
Characteristics of normal skin - ANS✔✔ Dry, supple, acidic.
What are the risks associated with overhydrated (macerated) skin? - ANS✔✔ More vulnerable
to friction/shear damage, pressure injury development, and linear cracks/fissures at the base of
skin folds.
How should one manage overhydrated (macerated) skin? - ANS✔✔ It is important to keep the
skin cool and dry to prevent complications.
What are the two main layers of the skin? - ANS✔✔ Epidermis and dermis
What contributes to skin strength and protection against damage? - ANS✔✔ Interlocking
configuration/cohesion between epidermis and dermis
Who is more vulnerable to skin tears and adhesive damage due to the lack of normal
interlocking configuration in the skin layers? - ANS✔✔ Neonates, newborns, and elderly
individuals
Total thickness of skin layers - ANS✔✔ Approximately 2mm/0.2cm thick
Incontinence Associated Dermatitis mechanism of damage - ANS✔✔
overhydration/maceration, friction damage, yeast infection, damage caused by fecal enzymes.
,What are some methods for IAD prevention related to toileting and containment? - ANS✔✔ Use
of perianal pouch or another containment system for patients with diarrhea and fecal
incontinence
How can IAD be prevented through cleansing? - ANS✔✔ Cleansing with soft disposable cloths
and a pH balanced no-rinse cleanser
What is a recommended routine for IAD prevention involving moisturization? - ANS✔✔ Routine
use of a moisturizer to replace lost skin oils
What additional measures can be taken for IAD prevention in terms of cleansing and
protection? - ANS✔✔ Use of disposable impregnated wipes with cleanser and moisturizers, plus
a moisture barrier to protect the skin from urine and stool
Which types of moisturizers/barriers are good for protection against urine and solid stool? -
ANS✔✔ Petrolatum-based and dimethicone-based
Which type of moisturizer/barrier is good for protection against liquid stool? - ANS✔✔ Zinc
oxide
What is a characteristic of copolymer films in terms of application frequency? - ANS✔✔ They
require less frequent application
What technique must be used for the removal of any soiled paste when using zinc oxide? -
ANS✔✔ Gentle technique
What is the recommended treatment for denuded skin in IAD? - ANS✔✔ Zinc oxide
What is the recommended treatment for candidiasis in IAD? - ANS✔✔ Antifungal
, What technique should be used for the removal of zinc oxide in IAD? - ANS✔✔ Careful
technique without scrubbing or picking
Denuded skin - ANS✔✔ a condition that occurs when the skin's surface layers are removed
Copolymer film - ANS✔✔
What is the pathology of skin tears? - ANS✔✔ Loss of interlocking configuration/cohesion
between epidermis and dermis.
How does minor trauma cause skin tears? - ANS✔✔ It causes the epidermis to separate (shear)
from the dermis.
What skin conditions are at greater risk of skin tears? - ANS✔✔ Thin, fragile skin and macerated
skin.
Prevention of skin tears - ANS✔✔ Protective sleeves, gentle handling, maintenance of soft
supple skin (routine use of moisturizers), no tape applied directly to fragile skin (apply thin
hydrocolloid or thin silicon adhesive foam and then tape to that), use of adhesive removers to
remove tape
What are the steps for managing skin tears? - ANS✔✔ Cleanse, roll any viable flap back into
place, and dress with nonadherent dressing.
What are the dressing options for skin tears? - ANS✔✔ Nonadherent dressing plus wrap gauze
OR silicon adhesive foam OR nonadherent foam plus wrap gauze.
