Phleb NHA CPT Exam Review

The recommended antiseptic for cleaning capillary puncture sites is

• 70% isopropanol

• povidone-iodine

• soap & water

• tincture of iodine

The antiseptic must be completely dried before performing capillary puncture to avoid

• hematoma formation

• hemoconcentration

• premature clotting

• specimen hemolysis

Tests affected by povidone-iodine contamination of a capillary specimen include

• phosphorus

• potassium

• uric acid

• all of these answers

Errors in capillary glucose results have been attributed to

• excessive depth of the capillary puncture

• failure to collect the initial drop of blood

• isopropanol contamination of the specimen

• warming of the site before puncturing

Proper finger puncture technique would include all the following except

• choosing a middle or ring finger site

• puncturing parallel to the fingerprint

• trying not to squeeze or milk the site

• warming the site before puncturing
