What is the blood culture tube?
When using a butterfly on the hand, the patient may make this type of fist to make the veins stand out.
What is a loose fist?

What is the vacuum?
This additive is found in the light blue coagulation tube.
What is sodium citrate?

What are small veins?
An outdated evacuated tube may no longer have this.
What is the vacuum?

What is the lavender tube?
This color tube is used for coagulation testing and is drawn after the blood culture tube
What is the light blue tube?

With the syringe method, blood is obtained by pulling back on this part of the syringe.
What is the plunger?
An unlabeled specimen may be rejected by this department.
What is the laboratory?
This tube contains heparin and may be used for blood gases and pH testing.
What is the green tube?
If a butterfly is being used and a light blue tube is the first or only tube needed, this type of tube is drawn first and discarded.
What is a 5-mL red tube?
After entering the vein with a butterfly, the angle is decreased to approximately this many degrees.

What is the SST/gold or red-gray speckled tube?
The overall purpose of following the correct order of draw is to prevent this from occurring between different tubes and their additives.
What is cross-contamination that could cause inaccurate test results?
To prevent venous reflux when using a butterfly, the tube and holder should remain in this position.
What is downward?
After blood is collected using a syringe, the specimen must be transferred to this type of tube.
What is an evacuated tube?
Powdered additive tubes, such as gray-stoppered tubes, should be gently tapped below the stopper for this reason.
What is to dislodge the additive from the stopper and prevent erroneous test results?
