- What are some example of disinfectants:
- Corrosive chemical compounds, used on surfaces and instruments, and used to kill pathogenic microoganisms.

- 70% isopropyl alcohol.
- What is typically used to clean the site when collecting blood culture specimens?
- Povidone Iodine.
- What is the best solution to use to clean up blood spills?
- 1:10 sodium hypochlorite.
- Why are gauze pads a better choice than cotton balls for covering the site and holding pressure following venipuncture?
- Cotton ball fibers tend to stick to the site.
- What can be used on infants younger than 2 years of age:
- Evacuated tubes, Isopropyl alcohol, and tourniquets.
- What is a required characteristic of a sharps container?
- Leak-proof and puncture-resistant, locking lid, and marked with a biohazard symbol.
- When a disposable latex tourniquet becomes soiled with blood, it is best to:
- Thrown it away.
- Wearing gloves during phlebotomy procedures is mandated by the:
- Occupational Safety and Health Administation. (OSHA)
- What criterion do you use to decide which needle gauge to use for venipuncture:
- Size and condition of the vein.
- To what does the "gauge" of a needle relate?
- Diameter.
- Which needle gauge has the largenst bore?
- 18.
- Multisample needles are typicallly available in these gauges.
- 20-22.
- The slanted tip of a needle is called the:
- Bevel.
- The purpose of the rubber sleeve that covers the tube end of a nultiple-sample needle is to:
- Prevent leakage of blood during tube changes.
- A phlebotomy needle that does not have a safety feature:
- Must be using with a tube holder that has a safety feature.
- What criterion do you use to decide what size tubes to use for ETS blood collection?
- Age of the patient, amount of blood needed for the test, and size and condition of the patient's vein.
- Evacuated tubes are coated with silicon to:
- Keep blood from clinging to the sides of the tube.
- What stopper colors designates a tube used for coagulation testing?
- Light Blue.
- What tubes will yield a serum specimen?
- Red top.
- This test requires prepraration of a blood film on a glass slide.
- Manual Differential.
- What tube stopper colors indicate the presence (or absence)and type of additive in the tube:
- Green, lavender, and light blue.
- Heparin prevents blood from clotting by:
- Inhibiting thrombin.
- What department would most likely perform the test on a specimen collected in a sodium polyanethol sulfonate (SPS) tube?
- Microbiology.
- A royal blue top with green color-coding on the label contains:
- Heparin.
- What substances interfere with the action of calcium in the clotting process:
- EDTA, Potassium Oxalate, and Sodium Citrate.
- It is important to fill oxalate tubes to the stated fill capacity because excess oxalate:
- Causes Hemolysis.
- What substances is contained in a serum separator tube?
- Thixotropic Gel.
- What is the purpose of an antiglycolytic agent?
- Preserve Glucose.
- Glass particles present in serum separator tubes:
- Accelerate clotting.
- What is the best tube for collecting an ethanol (ETOH)specimen?
- Gray top.
- Identify the tubes needed to collect a complete blood count (CBC), partial thromboplastin time (PTT), and STAT potassium by color and in the proper order of collection for a multi-tube draw.
- Light blue top, green top, and lavender top.
- During venipunture the tourniquet should not be left on longer than:
- 1 minute.
- What tubes is filled first when multiple tubes are filled from a syringe?
- A blood culture tube.
- This test is collected in a light blue tube.
- Prothrombin Time.
- What STAT tests is typically collected in a lithium heparin tube?
- Electrolyte.
- This tube stopper indicates that the tube contains EDTA.
- Lavender.
- What anticolagulant is contained in a serum separator tube?
- There is no anticoagulant in a serum separator tube.
- The purpose of sodium citrate in specimen collection is to:
- Protect coagulation factors.
- The part of a syringe that shows measurements in cc or mL is called the:
- Barrel.
- The part of the evacuated tube holder that is meant to aid in smooth tube removal.
- Flange.
- The best choice of equipment for drawing difficult veins is:
- Butterfly and evacuated tube holder.
- Mixing equipment from different manufacturers cna result in:
- Improper needle fit, needle coming unscrewed, and tubes popping off.
- You are most likely to increase the chance of hemolyzing a specimen if you use a:
- 25-gauge butterfly needle to collect a specimen from a child.
- The purpose of a tourniquet in the venipuncture procedure is to:
- Enlarge veins so they are easier to find and enter.
- If a blood pressure cuff is used for venipuncture in place of a tourniquet, the pressure used must be:
- Below the patient's diastolic pressure.
- An anticoagulant:
- Binds calcium or inhibits thrombin, keeps the blood from clotting, and prevents coagulation.
- What qualities are required for needle safety devices:
- Allow the user's hand to remain behind the needle at all times, create a barrier between the hands of the user an the needle after use, and one handed activation.
- An EDTA tube that contains gel separator is called a(n):
- Plasma Preparation Tube. (PPT)
- What additive contains a substance that inhibits phagocytosis of bacteria by white blood cells?
- Sodium Polyanethol Sulfonate. (SPS)
- What type of test is most affected by tissue thromboplastin contamination?
- Coagulation.
- What tests would be most affected by carryover of K2EDTA?
- Potassium.
- What microcollection containers should be filled first if collected by skin puncture?
- Lavender stopper.
- The intent of the alternate syringe order of draw is to:
- Minimize microclot formation in anticoagulant tubes.
- A pink top tubes containing EDTA is primarily used for:
- Blood bank tests.
- A blood smear made from blood collected in a container with a lavender stopper should be prepared within:
- 1 hour of specimen collection.
