APSC 4464 EXAMINATION QUESTIONS WITH
ANSWERS
Non-Swedged Needles - practically a sewing needle where the suture passes through the
eye of the needle. The margin of the needle is surpassed by the suture material; this causes
more trauma and increases the healing process.
Swedged Needles - a needle where the suture is embedded into the shaft of the needle.
The margin of the needle is not surpassed by the suture material which decreases the trauma
and healing process.
Tensile - the amount of strength required to tear/rip something.
Simple Interrupted Suture Pattern - PRO: good apposition of margins; loss of one suture
has minimal effect.
CON: takes more time than continuous suture patterns; may tear through tissue when tension is
present.
Horizontal Mattress Suture Pattern - PRO: good for areas of high tension; loss of one
suture has minimal effect
CON: may strangulate blood flow and affect healing; causes eversion of margins.
Vertical Mattress Suture Pattern - PRO: good for areas of high tension; not as likely to
cause blood restriction
CON: takes longer than continuous patterns; causes eversion of margins.
Simple Continuous Suture Patterns - PRO: very fast to complete; fair apposition of
margins.
CON: may tear through tissue when tension is present; breakage of one suture will result in the
unraveling of the whole suture.
