Collection ProceduresQuestion 28 of 100
An 88-year-old patient has thin skin, fragile veins and takes warfarin. Which modification is most appropriate?
a.Use a 16 gauge needle so the draw finishes faster
b.Slap the arm firmly to raise the vein
c.Apply the tourniquet as tightly as possible
d.Anchor the vein without dragging the skin, use a 23 gauge winged set, and hold pressure longer after the draw
Explanation
Older skin tears easily and anticoagulated patients bleed longer, so gentle anchoring, a smaller winged needle and extended pressure after needle removal are appropriate. Slapping the arm and overtightening the tourniquet bruise fragile tissue and can rupture the vein. A large bore needle increases trauma without any benefit for a routine draw.
