Question

Which of the following equipment may be used in performing venipuncture on small, fragile veins?

1) Butterfly needle
2) Vacutainer tube
3) Needle
4) Blood pressure cuff

Answer 1

In venipuncture, a butterfly needle is best suited for small, fragile veins due to its smaller size and greater control.

Step-by-step explanation:

When performing venipuncture on small, fragile veins, the recommended equipment to use is a butterfly needle. This type of needle is smaller and has wings for better control, which makes it ideal for accessing delicate veins without causing too much damage or discomfort. In contrast, while a Vacutainer tube is commonly used for blood collection, it is typically attached to a larger needle that might not be suitable for fragile veins. A standalone needle also generally refers to a larger gauge needle used for venipuncture. The blood pressure cuff, though not directly used for venipuncture, can be employed to aid in engorging the veins to make them more visible, but it is not used to puncture the vein itself.
