| phlebotomist | An individual who collects blood specimens is known as a (n): |
| skin punctures, arterial punctures, and venipunctures | Phlebotomy includes: |
| butterfly method, syringe method and vacuum tube method | Methods for performing venipuncture include: |
| Laboratory directory | When collecting a venous blood specimen to be transported to an outside laboratory for testing, what should be consulted for information on collecting and handling requirements? |
| Ask the patient to state his or her full name and DOB | What is the proper method for identifying a patient before performing a venipuncture? |
| label each blood tube with one unique patient identifier | A guideline that should not be followed when assembling equipment and supplies for a venipuncture are: |
| Semi-Flowler | What position should be used for a venipuncture if a patient appears nervous or has fainted in the past from a venipuncture? |
| “This procedure will not hurt” | You need to collect a venous blood specimen from a patient to run an FBG. What statement would be inappropriate to make to the patient during this procedure? |
| keeping the patient’s arm in a downward position | When collecting a blood specimen using the vacuum tube method of venipuncture, venous reflux is prevented by: |
| make the patient’s veins more visible and easier to palpate | The purpose of applying a tourniquet when performing venipuncture is to: |
| placing the tourniquet 3-4 inches above the bend in the elbow, asking the patient to clench their fist, and applying the tourniquet so that it is snug, but not tight | The following are correct techniques for applying a tourniquet: |
| It may be uncomfortable for the patient, inaccurate test results may occur, arterial and venous blood flow may be obstructed | This may occur if a tourniquet is applied too tightly? |
| Median cubital vein | Which antecubital veins are considered the best vein to use for a venipuncture? |
| Using the thumb to palpate the vein | The following represents an error in technique when selecting a vein for venipuncture? |
| Pulsates when palpated, has a more elastic and thicker wall than a vein, if punctured, blood is bright red in color and the patient will feel more than the usual amount of pain | The following are characteristics of the brachial artery (located in the antecubital space)? |
| They have a tendency to roll, they are more difficult to stick, the procedure is more uncomfortable for the patient and the hand veins are more susceptible to collapsing | Why should the veins of the hands be used as a venipuncture site only as a last resort? |
| plasma, buffy coat, and blood cells | On standing, a blood specimen to which an anticoagulant has been added separates into: |
| From clotted blood that has been centrifuged | How is serum obtained? |
| using a tube containing an anticoagulant | Whole blood is obtained by: |
| Removing the plastic holder from the needle for reuse | When performing a venipuncture, the following techniques represent a violation of the OSHA standard? |
| 21 G | Which of the following gauge needles is used most often to perform a routine venipuncture using the vacuum tube method? |
| amount of specimen required for the test | The size of the evacuated tube you choose to obtain a venous blood specimen depends on the: |
| EDTA | An evacuated tube with a lavender stopper contains: |
| Lavender | What color stopper tube is used to collect a blood specimen for a complete blood cell count (CBC)? |
| Light blue | What color stopper tube is used to collect a blood specimen for a prothrombin time test? |
| Red/gray, gold, red, and light blue | The following evacuated tubes can be used to collect serum: |
| The tube may no longer have a vacuum | What may occur if an outdated evacuated tube is used to collect the blood specimen? |
| Red, green, lavender, gray | Indicates the correct order of draw for the vacuum tube method of venipuncture? |
| Shaking a tube containing an anticoagulant after drawing it | What represents an error in technique when working with evacuated tubes? |
| Gently invert the tube five times after drawing it | What should be performed if an evacuated tube contains a clot activator? |
| The amount of blood specimen that can be collected is limited by the size of the syringe | What is a disadvantage of using the syringe method of venipuncture? |
| Scarred skin, bruised skin, an area that is painful to the patient and burned skin | What should not be used as a venipuncture site? |
| stiff and hard | On palpation, a scarred vein feels: |
| Applying firm pressure below and to the side of the vein | The following techniques can be used to prevent a vein from rolling? |
| The needle may enter the skin above the vein and not puncture it | What may occur if an angle of less than 15 degrees is used to perform the venipuncture? |
| moving the needle after it has been inserted into the vein | What results in patient discomfort during the venipuncture procedure? |
| Small veins | The following veins are most likely to collapse when performing a venipuncture? |
| use the butterfly method to perform the draw | If you think a vein selected for venipuncture may collapse, you should: |
| immediately remove the tourniquet and then the needle | During the venipuncture procedure, a sudden swelling occurs in the area around the puncture site. You should: |
| Bleeding may occur around the puncture site | What may occur if the needle is removed from the arm before removing the tourniquet? |
| Using a needle with a small lumen to collect the specimen | What may cause a result in hemolysis of the blood specimen? |
| inaccurate test results | Hemolysis of a blood specimen results in: |
| protect the patient from injury | You are performing a venipuncture, and the patient becomes dizzy and is about to faint. Your first priority in this situation should be to: |
| Glucose, hormones, chloride and antibodies | The following is found in the serum of blood? |
| 10-ml SST | Your physician has requested an electrolyte profile on a patient. The laboratory directory indicates this test requires 4 mL of serum. Which tubes should be used to collect the specimen? |
| allow the specimen to stand in an upright position for 30-45 minutes | After drawing a blood specimen for an electrolyte profile, the next step is to: |
| interfere with adequate serum collection | If a fibrin clot formed in the serum layer of a blood specimen, it would: |
| transporting electrolytes needed by the cells, nutrients needed by the tissues, picks up wastes from the tissues and transports antibodies, enzymes and hormones | Plasma functions in: |
| Lateral part of the third fingertip | Which sites can be used to make a skin puncture on an adult? |
| penetration of the bone | What may occur if a finger puncture is made that is deeper than 3.1 mm? |
| Using the first drop of blood for the test | The following represents an error in technique when obtaining a capillary blood specimen? |
| diluting the blood sample with tissue fluid | When performing a capillary puncture, the finger should not be squeezed to avoid: |
