65. Which of the following needles should a phlebotomist use for collecting units of blood for donation
Answer: B
A phlebotomist should use a 16-gauge needle for collecting units of blood for donation.
Using a 16-gauge needle is optimal for blood donation as it allows for efficient and rapid blood flow, which is crucial during the donation process.
A) 12gauge
A 12-gauge needle is too large for blood donation. While it allows for a very high flow rate, it can cause excessive trauma to the blood vessel and increase the risk of complications, making it unsuitable for this purpose.
B) 16gauge
The 16-gauge needle is the recommended size for blood donation. It strikes a balance between sufficient blood flow and minimizing discomfort for the donor, ensuring a safe and efficient collection process.
C) 21gauge
A 21-gauge needle is smaller than recommended for blood donation. While it can be used for certain blood draws, it may slow the collection process and is generally not preferred for whole blood donations.
D) 23gauge
A 23-gauge needle is too small for blood donation purposes. It would significantly slow down the collection of blood and could lead to discomfort for the donor, making it an unsuitable choice for this procedure.
Conclusion
The 16-gauge needle is the appropriate choice for blood donation as it facilitates a rapid and safe collection process while minimizing discomfort for the donor. In contrast, the other options either present risks of complications or are inadequate for the volume of blood that needs to be collected.
