Phlebotomy Technician Practice Exam (NCPT/CPT)

Improper venipuncture technique can result in issues such as blood clots, infection, and separation of the blood components. However, the most immediate effect of improper technique is the introduction of bubbles into the sample. Bubbles can alter the composition and measurement of the blood, potentially leading to inaccurate results. It is important to properly prepare the venipuncture site, use the correct equipment, and follow protocol to avoid this issue. Option C, infection, can occur if proper hygiene measures are not taken before and after the procedure. Option D, separation, can also occur if the tube is not properly mixed after collection.
