Questions and Answers
  • 1. 
    1.    LouAnn-Sue-Lyn has been brought to the ER because when her friend Anita Ride came over to see if she could borrow Louann’s car, she found her friend with her bad foot (it had become badly ulcerated over the last few months) up on the table and it was looking really bad and stinking.  The physician ordered HBO therapy, and after figuring out that it would not entail watching television Louann began treatments.  Which of the following below could apply to Louann’s wound and ensuing therapy.A.    HBO would not be good because of vasoconstrictionB.    HBO would lead to neovascularization.C.    HBO would lead to hyperoxygenation of blood and tissueD.    HBO would help enhance immune function
