Question 1

Which vein is considered the FIRST choice for routine venipuncture in adults?

The median cubital vein is preferred because it is large, well-anchored, and least likely to roll or bruise.

Question 2

A patient's blood culture requires two sets of draws. What is the correct sequence for filling the bottles?

Answer

Aerobic bottles are filled first to match the ambient air present in the needle/tubing before anaerobic conditions are introduced.

Royal blue tubes without additive are manufactured from metal-free materials to prevent contamination of trace-element samples.
