Clean-catch midstream collection

Clean-catch midstream collection reduces external contamination by cleaning the genital area and discarding initial urine before collecting the specimen.

Question 2

When performing a venipuncture, which vein is most commonly used for blood draws in adults?

Accepted Answer

Median cubital vein

Answer

The median cubital vein in the antecubital fossa is the preferred site due to its large size, stability, and accessibility.

Question 3

What is the purpose of applying a tourniquet before venipuncture?

Accepted Answer

To distend the veins and make them more accessible

Answer

A tourniquet temporarily restricts venous blood return, causing veins to engorge and become more visible and palpable for needle insertion.

Question 4

Which tube color is used for a complete blood count (CBC) collection?

Accepted Answer

Lavender/purple top (EDTA)

Answer

The lavender/purple top tube contains EDTA anticoagulant, which preserves cell morphology and is required for CBC analysis.

When administering an intradermal injection for a tuberculosis (TB) skin test, what is the correct angle of needle insertion?
