CWS QUESTIONS WITH
COMPLETE/VERIFIED ANSWERS
Q : A patient's wound is producing copious amounts of thick blue - green drainage . What
technique should you use for the most definitive identification of the offending organisms ?
A. Anaerobic swab culture
B. Tissue biopsy
C. Fluid aspiration
D. Serologic examination - correct answer ✔✔ Answer : B Explanation : Several methods of
wound culturing exist ; tissue biopsy is the gold standard . Tissue biopsies are performed by a
physician or podiatrists and involve removing a sample of living tissue from the wound for
examination . Tissue biopsies have been favored because they allow quantification of organisms
as well as visualization of organisms invading the viable tissue .
Q : Covering a wound with a sterilized graft harvested from a pig would be an example of which
of the following types of grafts ?
A. Allograft
B. Autograft
C. Isograft
D. Xenograft - correct answer ✔✔ Answer : D Explanation : A xenograft is a transplant from
another species such as a pig . Allografts are the most common type of graft and are a
transplant from non - identical donors . Autografts are grafts from the same individual such as a
split thickness skin graft commonly performed in burn management . Isografts are from
genetically identical people such as an identical twin .
Q : Which of the following topical agents is noted for its ability to dehydrate proteins and
dissolve lipids ? A. Ethyl alcohol
B. Chlorhexidine
, C. Sodium hypo chlorite
D. Povidone iodine - correct answer ✔✔ Answer A
Explanation: Ethyl alcohol, in addition to being bactericidal and virucidal, has the action of
dehydration of proteins and dissolving lipids. This may cause dryness and irritation of intact
skin. Chlorhexidine is a biguanide that acts by damaging the cell membrane.
It is relatively safe and has a minimal effect on tissue. Sodium hypochlorite works by cell lysis
and works as a deb riding agent in necrotic wounds. Povidone iodine iodinates proteins and
inactivates them while oxidizing cell constituents.
Q : Contact kilohertz ultrasound is CONTRAINDICATED in wounds that
A. are locally infected .
B. have impaired circulation .
C. need debridement .
D. are associated with implanted electronic devices . - correct answer ✔✔ Answer : D
Explanation : Contact kilohertz ultrasound is primarily indicated for debriding and cleaning up
wounds that have local infection . Likewise , it can be used in areas of impaired circulation since
it is not highly invasive and can often work without causing any bleeding . Both kilohertz and
megahertz ultrasound are contraindicated in the presence of implanted electronic devices as
they have the potential to disrupt the function of the device .
Q : In debriding a patient's wound you encounter a darkish yellow tissue that is globular in
nature . This most likely represents
A. fascia .
B. necrotic adipose tissue .
C. desiccated tendon .
D. cartilage . - correct answer ✔✔ Answer : B Explanation : Adipose tissue is globular in nature
and tends to be pale yellowish - white in appearance . As it becomes necrotic , it will become
dark yellow . Fascia is a dense fibrous tissue that is shiny and white in appearance and will turn
yellow or black as necrosis sets in . Tendons are also fibrous bands that appear shiny and white
the healthy state . They will turn yellowish - brown to black as they desiccate . Cartilage appears
