    • involves less pain and discomfort because of its multiple uses
    • reliable
    • cost effective
  30. When changing PICC dressings remove the old dressing from
    distal to proximal edge

    apply moist heat or gentle massage to upper arm and reattempt removal in 20-30 minutes.
  32. Which organism is responsible for most cases of catheter related bloodstream infections?
    Coagulase-negative staphylococci
