2. A patient is admitted to the hospital for possible septicemia. He has a
large pressure ulcer on his heel that is open and includes necrotic tissue.
However, his prothrombin time/international normalized ratio (PT/ INR)
, values are too high to permit surgical débridement at this time. The nurse
expects that which wound -care product will be used to treat the wound?
a. Cadexomer iodine
b. Biafine topical emulsion
c. Povidone-iodine
d. Collagenase
ANS: D
Because this patient has an elevated PT/INR, he cannot receive surgical
débridement because of concerns about excessive bleeding.
Collagenase is usefu l for patients taking anticoagulants and for those
in whom surgery is contraindicated; it selectivel y removes necrotic
tissue but does not harm normal tissue. Cadexomer iodine is not
appropriate for a wound with necrotic tissue. Povidone -iodine
(Betadine) is used as a skin cleanser; biafine is indicated for radiation
dermatitis.
