Phlebotomy Chap 3

The venipuncture step of primary importance to prevent rolling veins is

• tightly applying the tourniquet

• selecting the median cubital vein

• using a 23 gauge needle

• anchoring the vein while inserting the needle

the most important step in the venipuncture procedure is

• applying the tourniquet

• locating the best vein

• identifying the patient

• applying pressure to the puncture site

when collecting blood using a winged blood collection set with a 23 gauge needle, which of the following is acceptable

• raising the angle of insertion to 45 degrees

• collecting blood into a syringe

• using a 15mL evacuated tube

• filling the SST tube before the light blue stopper

prior to bandaging the puncture site, the blood collector should

• thank the patient

• instruct a fasting patient to eat

• examine the site for bleeding

• apply pressure for at least 15 minutes

Which of the following areas can be used for venipuncture

• deep cephalic vein

• from a hematoma

• arm with an IV running

• arm with a fistula

The minimum number of patient identifiers required by the Joint Commission is

• 1

• 2

• 3

• 4

Which of the following is the proper procedure to avoid a hematoma

• removing the tourniquet after removing the needle

• bandaging the patients arm right after needle removal

• firmly anchoring the vein in needle insertion

• having the patient bend the elbow and apply pressure

to avoid interference with test results the maximum time that a tourniquet can remain on is

• 1 minute

• 2 minutes

• 3 minutes

• 5 minutes

the needle is inserted into the vein at

• bevel up at 45- 50 degree angle

• bevel up at 15 to 30 degree angle

• bevel down at 15 to 30 degree angle

• bevel down at 45 to 50 degree angle

If a plunger on a syringe is pulled back too fast

• the patient will develop a hematoma

• the patient feels a stinging sensation

• excess needle movement is prevented

• the sample may be hemolyzed
