Question

KNOWLEDGE DRILL 7-3:TRUE/FALSE ACTIVITY The following statements are all false, Circle the one or two words that make the statement false, and correct word(s) that would make the statement true in the space provided. 1. Use of Band-Aids to hold pressure is not recommended because they tend to stick to the site and bleeding when removed because they dislodge the platelet plug that seals a puncture site. 2. A properly applied tourniquet is tight enough to restrict arterial flow out of the area but not so tig! restrict venous flow into the area. 3. A needle or tube holder that has a safety device is an example of a SESIP, which is the CLIA acron sharp with engineered sharps injury protection. 4. When drawing venous blood by syringe, the phlebotomist slowly pulls back the plunger, creating that causes the shaft to fill with blood. 5. A transfer device must be held horizontal when tubes are being filled to prevent blood in the tube touching the needle within the transfer device. 6. An additive tube must be gently inverted two to four times, depending on the type of additive and manufacturer, immediately after collection to adequately mix the additive with the specimen. 7. Vigorous mixing or an excessive number of inversions in light-blue tubes can activate white cells clotting times. 8. When using the ETS system, royal blue tops for trace element studies should be collected first to the smallest amount of carryover. 9. The most common antimicrobial agent is sodium fluoride. It preserves glucose and inhibits the gr bacteria. 10. Sodium fluoride in tubes has been the source of more carryover problems than any other additive 11. Glycolysis occurs faster in newborns because their metabolism is decreased. 12. Coagulation tubes require a 9:1 ratio of additive to blood. 13. Coagulation specimens are placed on a mechanical rotator to keep them from settling out. 14. Using a needle with a diameter larger than a 25-gauge increases the chance of hemolysis. 15. The FDA has banned the use of latex gloves ie medicine because they pose a danger to human hi

Answer 1

1. Use of Cotton balls to hold pressure is not recommended because they tend to stick to the site and bleeding when removed because they dislodge the platelet plug that seals a puncture site.
2. A properly applied tourniquet is not tight enough to restrict arterial flow out of the area but not so tig! restrict venous flow into the area.

3. A needle or tube holder that has a safety device is an example of a SESIP, which is the OSHA acron sharp with engineered sharps injury protection.

4. When drawing venous blood by syringe, the phlebotomist slowly pulls back the plunger, creating that causes the barrel to fill with blood.

5. A transfer device must be held vertical when tubes are being filled to prevent blood in the tube touching the needle within the transfer device.

6. An additive tube must be gently inverted five to ten times, depending on the type of additive and manufacturer, immediately after collection to adequately mix the additive with the specimen.

7. Vigorous mixing or an excessive number of inversions in light-blue tubes can activate platelets and shortens the clotting times.

8. When using the ETS system, royal blue tops for trace element studies should be collected separately to the smallest amount of carryover.

9. The most common antiglycolytic agent is sodium fluoride. It preserves glucose and inhibits the breakdown of glucose

10. EDTA in tubes has been the source of more carryover problems than any other additive

11. Glycolysis occurs faster in newborns because their metabolism is increased

.12. Coagulation tubes require a 9:1 ratio of Blood to additive.

13. Coagulation specimens are placed on a mechanical rotator to separate plasma from blood.

14. Using a needle with a diameter larger than a 21 gauge increases the chance of hemolysis.

15. The FDA has banned the use of powdered gloves ie medicine because they pose a danger to human hi
