Q

IV Sites

A

When possible, avoid drawing blood from an arm that has an IV in place. If no alternate site is available, be sure to perform specimen collection from a site that is distal (below) the IV site

17
Q

Specimen collection

A

Collecting specimens in the correct tubes and following the proper order of draw will help to prevent contamination or interference

18
Q

Tourniquet application

A

Typing a tourniquet too tightly can result in hemoconcentration or an increase in the proportion of cells to plasma

19
Q

Select proper antiseptic agents for the test

A

Before routine venipuncture selection, the patients skin is cleaned with antiseptic to prevent contamination by normal skin flora

20
Q

Needles-part of a multi-sample needle

A

Bevel, shaft, hub, graduated barrel, plunger

21
Q

Proper capillary equipment and site

A

Capillary puncture is also known as skin puncture, microcapillary stick or finger stick

22
Q

Proper capillary equipment and site

A

Skin is punctured with lancet. This is used to obtain small amount of blood.

23
Q

Proper capillary equipment and site

A

Use alcohol for disinfection not iodine (as it leaves residue and affect the test result) using a circular motion from the inside out.

24
Q

Capillary equipment and site-equipment

A

Gauze, bandages, peppers, clay sealer tray, glass slides, gloves, lancets, micro collection containers, microhematocrit tubes , spring loaded puncture device

25
Q

Site selection

A

First choice if site middle or ring finger, second choice of site index/pointer finger and thumb do not use the pinky finger because of thinner tissue. Non-dominant hand
