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. Use of bandaids to hold pressure is not re Pandaids to hold pressure is not recommended because they tend to stick to the site and reinitiate bleeding when removed because they dislodge the platelet plug that seals a pun 2. A properly applied properly applied tourniquet is tight enough to restrict arterial flow out of the area but not so tight as to restrict venous flow into the area. be holder that has a safety device is an example of a SESIP, which is the CLIA acronym for a sharp with engineered sharps injury protection. when drawing venous blood by syringe, the phlebotomist slowly pulls back the plunger, creating a vacuum that causes the shaft to fill with blood. 5. A transfer device must be held horizontal when tubes are being filled in order to prevent blood in the tube from touching the needle in the transfer device. 6. An additive tube must be gently inverted two to four times, depending on the type of additive and the man facturer, 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 and lengthen clotting times. 8. When using the ETS system, royal blue tops for trace element studies should be collected first to avoid even the smallest amount of carryover. 9. The most common antimicrobial agent is sodium fluoride. It preserves glucose and also inhibits the growth of bacteria. 1. Sodium fluoride in tubes has been the source of more carryover problems than any other additive

Answer 1

1. The cotton fibers tend to stick to the site and removes the platelet plug and can re-initiate bleeding

2. A properly applied tourniquet is tight enough to restrict venous flow out of the area but not so tight to restrict arterial flow into the area.

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

4.

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

7. Vigorous mixing or an excessive number of inversions in lavender top tubes can lead to hemolysis

False, happens in green tubes
