80 multiple-choice questions and 21 flashcards on Venipuncture and Capillary Puncture Procedures, about 48% of the Phlebotomy Technician Certification bank. Every one carries a written rationale.
Venipuncture and Capillary Puncture Procedures is one of 5 chapters in CoStudy's Phlebotomy Technician Certification bank, and it holds 80 of the bank's 166 multiple-choice questions — roughly 48% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.
Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.
7 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.

4 cards from the 21 in this chapter.
Hematoma?
Bleeding into surrounding tissue. Causes bruise + swelling. Stop draw, apply firm pressure, ice if severe. May indicate vein blown.
How does arterial blood typically appear compared to venous blood during collection?
Arterial blood is bright red and fills the tube rapidly with a pulsing pattern, versus the slower, dark red flow of venous blood.
Veins to AVOID?
Sclerosed (hard), thrombosed (lumpy), recently injured, hematoma, edematous, burn, mastectomy side (no draw on side with lymph node dissection), arm with IV running.
Glucose tolerance test (GTT)?
Fasting baseline → patient drinks glucose load → blood drawn at 1 hr, 2 hr (sometimes 3 hr). Patient must remain seated + fasting between draws. Gray top tubes.
These are a sample. The full Venipuncture and Capillary Puncture Procedures chapter runs 101 items with per-chapter progress tracking, on the web and in the iOS app.
