How long should a tourniquet be applied during a blood draw?
No longer than 1 min due to increased risk of hemolysis. If accidently applied longer than 1 min, you must remove the tourniquet and wait 2min before you reapply and do the blood draw.
How do you label peripheral venipuncture?
Pt name, DOB, AHC #, date & time sample taken, who took sample, site sample taken
What is the first sample type drawn FIRST from a peripheral venous blood draw
cultures
At what angle do you perform a peripheral IV cannulation?
15-30 degrees
What is the first sample type drawn FIRST from a peripheral venous blood draw

What is the last sample drawn from a peripheral venous blood draw
Paxgene tubes
What is the most COMMON complication with peripheral IV cannulation
failure to extract blood
How do you prep a vein for venipuncture?
Prep the vein as you would when starting an IV, use alcohol or iodine pad and cleanse the area in a circular motion, starting from the inside and working your way out.
What are the primary influencing factors that negatively impact your reading of a peripheral venous blood draw (5)
- Under/overfilled containment
- tourniquet on for too long (greater than 1 minute)
- improper mixing mixing of tubes
- Hemolysis
- specimen contamination
Why would the venous blood sample be rejected by the lab
no label, inadequate volume, hemolysis, coagulated blood, delay, contaminated
How do you measure the probe for Invasive Core Temperature Monitoring?
Oral insertion: Measure from corner of mouth to the earlobe to 2 cm above the xyphoid process.
Nasal Insertion: Measure from the nose to the earlobe to 2 cm above the xyphoid process.
After the Invasive Core Temperature Monitoring probe has been inserted, what are the next steps?
Secure the probe, attach to temperature cable and monitor, reassess and document. Monitor patient for complications.
what are the indications for radial artery puncture/blood draw
