A variety of medical tests are performed by nurses and phlebotomists.This article will teach you how to draw blood.
Step 1: Patient precautions should be observed.
There are signs behind the patient's bed or on the chart.If the blood test requires a fast, make sure that the patient fasted for the right amount of time.
Step 2: Introduce yourself to your patient.
Explain what you are going to do as you draw blood.
Step 3: Put your hands in a container and wash them.
Put sanitary gloves on.
Step 4: The patient's order should be reviewed.
The patient's name, medical record number and date of birth are stamped on the requisition.Make sure the labels match the patient's identification.If you want to confirm the patient's identity, you can ask for a name and date of birth.
Step 5: You need to assemble your supplies.
Blood collection tubes, a tourniquet, cotton balls, bandage or medical tape, and alcoholic wipes should be in front of you.Make sure that your blood culture bottles have not expired.
Step 6: The appropriate needle can be selected.
The amount of blood you plan to draw, the patient's age, and physical characteristics will all affect the type of needle that you choose.
Step 7: The patient should be seated in a chair.
The chair should support the patient's arm but not have wheels.The patient's arm should not be bent at the elbow.Place a pillow under the patient's arm if they are lying down.
Step 8: Do you want your patient to decide which arm you draw from?
Tie a tourniquet around the patient's arm about 3 to 4 inches above the venipuncture site.
Step 9: The patient is asked to make a fist.
The patient should not be asked to pump his or her fist.
Step 10: You can trace the patient's veins with your index finger.
Use your index finger to tap the vein.
Step 11: If you plan to puncture the area with an alcohol wipe, make sure it's clean.
Don't drag the wipe over the same piece of skin twice, use a circular motion.
Step 12: The area should be dry for 30 seconds so that the patient doesn't feel a sting.
Step 13: It's a good idea to inspect your needle.
The end should not have hooks that restrict the flow of blood.
Step 14: The holder has a needle in it.
The holder needs to be secured with the needle sheath.

The skin should be pulled taut by your thumb below the puncture site.Make sure the patient's arm points down.
Step 18: Put the needle in the vein.
The bevel needs to be up.

The collection tube should be pushed toward the holder until the butt end of the needle pierces the tube.The tube should be below the puncture site.
Step 20: The tube should be allowed to fill.
As soon as blood flow into the tube is adequate, discard the tourniquet.
Step 21: When the blood flow stops, remove the tube from the holder.
Inverting the tube 5 to 8 times will mix the contents.Shake the tube slowly.
Step 22: Continue filling the remaining tubes until you're done.
