31
Q

CVAD blood draw considerations

A

Stop any infusions beforehand
Aspirate to verify blood return
Flush with 9 mL
Waste 3-5 mL and discard
Collect sample
Flush with 19 mL

32
Q

Preventing hemolysis

A

Problem free venipuncture
Use a larger bore needle to draw -21 22 or 23 gauge
Use larger needles for transferring blood into test tubes -18 g blunt fill works well
Tilt blood tubes so that the blood washes down the side of the tube
Aspirate slowly when collection from veins or catheter

33
Q

Blood cultures

A

Priority to minimize risk of contamination
Blood cultures when ordered should be collected first
5-10 mL of blood should be collected for each sample
Never attach blood culture bottles directly onto vacuholers because beads in the culture bottle can be introduce into the patients vein

34
Q

Trouble shooting

A

Change the position of the needle
Tourniquet too tight- could obstruct blood flow
Change tubes- vacuum could be a problem
Re anchor the vermin some veins roll
Have patient make a fist to help engorge muscles
Prewarlm area of venipuncture to increase blood flow
Rehydrate patient
