Q

What are tourniquets

A
  • rubber tubing or strapping that is wrapped around
    the arm to slow the flow of venous blood (blood in the veins)
  • causes a backup
    of blood and increased pressure

    make it easier to locate a patient’s veins.
    -applied 3 to 4 inches
    above the puncture site, tightly enough to slow the blood flow but not stop it

Q

types of safe needles

A
  • self blunting - After the blood is drawn, a
    push on the collection tube
    moves the blunt needle
    forward through the outer shell
    and past the needle point. The
    blunt point can be activated
    before it is removed from the
    vein or artery.
  • self blunting butterfly needle - After collection and before the
    removal of the needle, the wing
    is flipped to the other side,
    blunting the needle.
  • hinnged cap - use thubm to flip protective hinge cap
  • protective sheuld- plastic cover over needle
  • retractable needle- springloaded and retracts into barrel

volume. Volumes are indicated on the tube label with a line. The tubes that
draw less volume are often used for pediatric blood collection. Older-style
tubes for pediatric blood collection are physically smaller with a colored rubber stopper
