The CXR image shows a small right infiltrate. The physician suspects an embolism, either fat or pulmonary,
  and orders a STAT spiral CT scan of the lungs. The interpretation of the results reads strongly suggestive
  of a pulmonary embolus (Pe)
 
  What are the most likely sources of the embolus?
  What will be an ideal response?

Question 2

H.K. returns to surgery. The wound over H.K.'s fracture site has become necrotic with purulent drainage.
  The wound is debrided and cultured and a posterior splint is applied. H.K. returns to his room with orders
  for wet-to-moist dressing changes.
 
  The physician suspects osteomyelitis and orders nafcillin (unipen) and
  ciprofloxacin (Cipro). Contact precautions are implemented.
  Why are two antibiotics ordered?
  What will be an ideal response?
