Question 35

Multiple sample needle

For a routine venipuncture procedure using the evacuated tube method, a phlebotomist should use a multiple sample needle, which is designed specifically to draw blood into evacuated tubes efficiently.

A) Multiple sample needle

This option is correct as a multiple sample needle is the standard equipment used in the evacuated tube method, allowing for the collection of blood samples without needing to change the needle between tubes. Its design facilitates the smooth transfer of blood into multiple tubes while minimizing discomfort for the patient.

B) Winged infusion syringe set

This option is incorrect because a winged infusion set, also known as a "butterfly" needle, is typically used for smaller veins or when accessing veins in difficult locations. It is not the preferred method for routine venipuncture with evacuated tubes, as it may not provide the same efficiency and ease of use as a multiple sample needle.

C) Syringe

This option is incorrect as using a syringe for routine venipuncture is not standard practice. While syringes can be used for blood collection, they are generally employed in situations where vacuum tubes cannot be used or when a more controlled draw is necessary, making them less suitable for routine collection via the evacuated tube method.

D) Lancet

This option is incorrect since a lancet is primarily used for capillary blood sampling, such as fingersticks, rather than for venipuncture. It is not designed for drawing blood from veins, and therefore does not meet the requirements for a routine venipuncture procedure using evacuated tubes.

Conclusion

The multiple sample needle is the ideal choice for a routine venipuncture procedure with the evacuated tube method, ensuring efficient blood collection with minimal patient discomfort. Other options either serve different purposes or are less suitable for this specific procedure, confirming that A is the definitive correct answer.
