Final answer:
A phlebotomist uses a 16 to 17 gauge needle for blood donation, which is the ideal size for efficiency and donor comfort. Proper sterile technique is essential to prevent infections.
Step-by-step explanation:
A phlebotomist, skilled in phlebotomy and medical lab technology, typically uses a needle that is 16 to 17 gauge in size for a blood donation. This size is ideal for collecting a sufficient volume of blood quickly, and for ensuring the donor's comfort and safety. Needles that are too large can cause discomfort and potential damage to the vein, while needles that are too small can slow the donation process and affect the quality of the blood collected. In blood donation, it's also essential to use a sterile technique to minimize the risk of infections. The equipment used for collecting blood, including the bags, are designed for safety and efficiency, ensuring that the blood can be easily collected and stored. Skilled phlebotomists are trained to handle various scenarios including venipuncture, capillary sticks, and arterial sticks, and they play a critical role in medical laboratories and blood donation centers.
