The catheter should be accessed minimally to decrease the risk of infection.6 Before a blood specimen is obtained from an arterial catheter with an open system, a certain amount of fluid, the discard volume, must be withdrawn. The exact amount of discard volume remains undefined and can depend on the test. Coagulation studies may require more discard than other tests. For a reliable coagulation test result, the literature suggests using six times the dead space in the catheter.5 Dead space is the space between the insertion site and the access point for blood sampling. A discard volume of two times the dead space removes the priming solution for noncoagulation studies.7 The minimum discard volume should be used to avoid hospital-acquired anemia. Closed systems reduce the incidence of hospital-acquired anemia by allowing the replacement of the dead-space volume. PATIENT AND FAMILY EDUCATION

Why must the first drop of blood from a capillary puncture be wiped away?Wipe away the first drop of blood because it may be contaminated with tissue fluid or debris (sloughing skin). Avoid squeezing the finger or heel too tightly because this dilutes the specimen with tissue fluid (plasma) and increases the probability of haemolysis (60).
When following the order of draw which of these tubes should always come first quizlet?CLSI recommends the following order of draw for skin puncture: Blood gases, EDTA tubes, Other additive tubes, then Serum tubes. The correct order of draw would be: two light blue top tubes (one waste and one for PT which is a coagulation test), green top tube (for the Chem 7), and the lavender top tube (for the CBC).
When drawing blood samples which of the following should be performed first?Step 1: Identify The Vein
The first step in drawing blood correctly is to identify the appropriate veins to puncture. For adult patients, the most common and first choice is the median cubital vein in the antecubital fossa.
When you Cannot perform a venipuncture successfully after two attempts you should?Verify that patient information on tubes and requisitions match. NOTE: When performing venipuncture if no success after two attempts, defer obtaining the blood sample to another authorized staff member.
