Question 89

23-gauge needles are appropriate for venipuncture using a winged infusion set and a 5 mL syringe.

The 23-gauge needle is suitable for drawing blood as it provides a balance between sufficient flow rate and minimal discomfort for the patient, making it ideal for venipuncture procedures.

A) 23-gauge

This option is correct because a 23-gauge needle offers an optimal size for venipuncture, ensuring adequate blood flow while minimizing trauma to the vein. It is commonly used in clinical settings for these purposes, particularly when using a winged infusion set.

B) 18-gauge

The 18-gauge needle is not suitable for this scenario as it is too large for venipuncture in most cases. While it allows for rapid blood flow, the size can cause significant discomfort and potential damage to smaller veins, making it less desirable for routine blood draws.

C) 25-gauge

A 25-gauge needle is generally too small for venipuncture, which can lead to a slower blood draw and increased risk of hemolysis. Using a needle of this size may prolong the procedure and is not typically recommended when a larger gauge, such as 23-gauge, is available.

D) 27-gauge

The 27-gauge needle is also too small for venipuncture, similar to the 25-gauge option. It would result in a very slow blood draw and may not be effective for obtaining the necessary volume of blood from a patient, especially when using a 5 mL syringe.

Conclusion

In summary, the 23-gauge needle is the most appropriate choice for venipuncture with a winged infusion set and a 5 mL syringe, providing an efficient balance between blood flow and patient comfort. The other options, while functional in certain contexts, either do not provide sufficient blood flow or may cause unnecessary discomfort, making them unsuitable for this specific procedure.
