◍ Which of the following graft measurements is equal to approximately
eighteen square inches of skin?
A. 2.5 cm X 15 cm
B. 5 cm X 10 cm
C. 5 cm X 15 cm
, D. 7.5 cm X 15 cm.
Answer: 7.5 cm X 15 cmNote: sq. inch area = length (in) x width (in)1 inch
= 2.54 cm (or 2.5 cm for easy math)(7.5 cm / 2.5 cm = 3 inches) x (15 cm /
2.5 cm = 6 inches) = 3 in x 6 in = 18 inches

C. The use of certain drugs may compromise the quality of tissues for
transplant.
D. It is only a deferral if shared needles were used..
Answer: B
◍ To fill an osseous defect, all of the following may be used EXCEPT:
A. Corticocancellous
B. DFDBA
C. Semitendinosis
D. Cancellous.
Answer: Semitendinosis. Note: An osseous defect is an imperfection of
absence of bony structures.Corticocancellous refers to bony tissue that
contains cortical and cancellous elements.DFDBA = Demineralized Freeze
Dried Bone Allograft.Semitendinosis is one of the three muscle that make
up the hamstring muscle group.Cancellous: bone tissue with a mesh-like
structure; typical of the interior of mature bones.
◍ You are currently completing the DRAI on a potential donor. The historian
stated that the potential donor used heroin four years ago. What must be
clarified before moving forward with the case?
A. The route of drug use. (e.g., ingested, snorter, smoked, injected.)
B. if the individual had an infectious disease testing panel ran in the last
year.
C. if heroin was used at the time of death.
D. if the potential donor had ever been charged with drug possession..
, Answer: A

Answer: B
◍ Allograft bone is commonly used for all of the following procedures
EXCEPT:
A. Dental procedures
B. Spinal fusion procedures
C. Arthroplasty
D. Total hip replacements.
Answer: D
◍ Why is screening, medical record review and DRAI review in evaluating
increased-risk behaviors, such as drug use, in addition to testing so
important?
A. To identify risk of a negative screen due to the window period.
B. The potential for a false negative screening.
, C. A non-reactive test due to viral suppression.
D. All of the above..

variant CJD (vCJD).
A. Three months
B. Six months
C. Ten years
D. Five years.
Answer: D
◍ Tissue may be stored in quarantine for each of the following reasons
EXCEPT:
A. The tissue is pending processing.
B. The tissue is pending discard.
C. The tissue is involved in a recall.
D. The tissue is ready for distribution..
Answer: D
◍ All human tissue processed or shipped prior to the determination of donor
eligibility
A. Must be under quarantine, accompanied by records assuring
identification of the donor and indicating that the tissue has not been
determined to be suitable for transplantation.
B. Should be kept in your office, accompanied by records assuring
identification of the donor and indicating that the tissue has not been
