Question

Chapter 8 Venipuncture Procedures 155 KNOWLEDGE DRILL 8-3: TRUE/FALSE ACTIVITY The following statements are all false Circle the one or two words that make the statement false and write the correct word(s) that would make the statement true in the space provided 1. When a computer generated label is used, the phlebotomist is typically required to write the time of receipt and the date of collection. 2. To avoid ID and mislabeling errors, some inpatient facilities require what is referred to as a two-way ID. Do not use veins on the top side of the wrist because nerves lie close to the veins in that area. 4. Either the needle, tube holder, or syringe selected must have a CLSI-required safety feature to help protect the user from accidental needlesticks. 5. After establishing the blood flow, release the tourniquet and ask the patient to squeeze the fist. 6. Although butterflies are available in various gauges, a 25-gauge butterfly is most commonly used for small and difficult veins. 7. For an antecubital site venipuncture, insert the needle into the skin at an angle of 30 degrees or more depending on the depth of the vein. 8. The Joint Commission recommends that procedures be in place to monitor the amount of blood that is drawn from pediatric, geriatric, and other vulnerable patients to avoid phlebotomy-induced anemia. 9. Laboratory testing personnel will assume that blood in microtubes is venous blood. 10. Venipuncture in children under the age of 2 should be limited to hand veins and not deep and hard-to-find veins. 11. According to CLSI standards, a venipuncture site should be cleaned using a circular motion. 12. Observe a venipuncture site for 20 to 30 seconds to be certain bleeding has stopped. 13. A patient who is NPO cannot have anything to eat or drink except water. 14. A blood pressure cuff inflated above the patient's diastolic pressure is sometimes used in place of a tourniquet. 15. The median cubital vein is in an area where nerve injury is more likely because it overlies the bicipital aponeurosis. 16. A patent vein is distended from being filled with blood. 1. You have more control over the needle the faster it goes into the arm. A medical record number is an example of a nonspecific identifier il multiple tubes are being collected, a tube can be mixed after the next tube is filled. Using a needle with an internal diameter larger than a 23-gauge can cause hemolysis of the specimen.

Answer 1

1) true- phlebotomist required to write the time of collection and his /her initials on the label after collecting the specimen.
2)True- verify name & DOB then check bracelet and notify for ID discrepancies .

3)False - veins on the Palmer of the wrist and lateral are suitable for venipuncture.while veins on the underside of the wrist should be avoided

4)True- 0.3% needlestick cases are filled every year which cause blood born disease to the user.

5)False-Ask the Patient to open fist

6)False-22 gauze needle usually used because 25-27 gauze needles can destroy blood or get clot due to the smaller sizes needle .

7)False- insert at 30-degree angle or less in smooth ,steady forward motion.

8)True- This can prevent unnecessarily withdrawing of blood .

9)True- blood withdrawn from vein.

10)True-main pancharan 2 years old child is limited to hand only.

11)True- Use circular motion,moving outward in widening concentric circles.

12)True - Clotting take time .

13)True- NPO means mil per oral .

14)True - but care must be exercised not to start the IV too close to the cuff,which causes excessive back pressure.

15)False- commonly used for venipuncture ,it lies over the cubital fossa and serve as anastomosis between cephalic and basilic veins.

16)True-collect the blood return from dilated paravertebral venous

17)True - it seems that it is going in right way.

18)True-medical record number is an example of a non specific identifier

19)False-every tube has specific function containing specific solution so we can't mix .

20)False- smaller diameter like 25-27 gauzes needles can cause hemolysis.
