Which of the following purposes is served by anchoring the selected vein for a venipuncture using a winged infusion set?
Eliminates the need for a tourniquet
Reduces the pain of needle insertion
Improves vein identification
Minimizes vein movement
The Correct Answer is D
Choice A Reason:
Anchoring the vein does not eliminate the need for a tourniquet. The tourniquet is applied to engorge the veins, making them more prominent and easier to puncture. Anchoring is a technique used after the tourniquet has already accomplished this task.
Choice B Reason:
While anchoring the vein can provide a more stable area for needle insertion, which might indirectly reduce pain, its primary purpose is not pain reduction. Pain during needle insertion is more directly influenced by the needle gauge, angle of insertion, and the phlebotomist's technique.
Choice C Reason:
Improving vein identification is not the direct purpose of anchoring. Vein identification is typically done visually and by palpation before the application of the tourniquet and before anchoring the vein. Anchoring is performed to stabilize the vein once it has been identified.
Choice D Reason:
The primary purpose of anchoring the vein is to minimize its movement during venipuncture. This is important because it helps prevent the needle from slipping out of or through the vein, which can cause discomfort and bruising, and may require another puncture attempt.

Correct Answer is D
Explanation
Choice A reason:
Leaving a patient's record on a countertop while assisting other patients is not an acceptable HIPAA practice. Patient records contain sensitive information and should be kept secure at all times to maintain confidentiality. Leaving them in a place where unauthorized individuals could potentially access them violates HIPAA regulations.
Choice B reason:
Discarding patient contact information in the trash is a violation of HIPAA rules. Any documents containing patient information must be disposed of through secure methods, such as shredding, to ensure that the information cannot be retrieved or used improperly.
Choice C reason:
Sharing passwords with anyone, including coworkers, is against HIPAA guidelines and general security best practices. Each staff member should have a unique login credential to ensure that access can be tracked and that each person is accountable for their actions within the system.
Choice D reason:
Discussing patient information with an assisting coworker is acceptable under HIPAA, provided that the coworker has a legitimate need to know the information for treatment, payment, or healthcare operations purposes. This type of sharing is necessary for collaborative care and is permitted as long as it is done in a manner that protects the patient's privacy.
Correct Answer is A
Explanation
Choice A reason:
A 23-gauge needle is commonly used for venipuncture with a winged infusion set and a small volume syringe like a 5 mL syringe. This size provides a balance between patient comfort and the ease of drawing blood without causing hemolysis or excessive damage to blood cells. It is large enough to allow blood to flow easily into the syringe but small enough to minimize discomfort and the risk of bruising.
Choice B reason:
An 18-gauge needle is quite large and is typically used for situations requiring rapid administration of fluids or for blood donation where larger volumes are collected quickly. It is not ideal for a standard venipuncture, especially with a small syringe, as it can cause more pain and increase the risk of bruising.
Choice C reason:
A 25-gauge needle is on the smaller side and may be used for patients with very fragile veins or for pediatric patients. However, it may not be the best choice for a 5 mL syringe as it could make the blood draw process slower and more difficult, potentially leading to clotting in the needle or syringe.
Choice D reason:
A 27-gauge needle is very small and is typically used for subcutaneous injections, such as insulin injections, rather than for venipuncture. It would be too small for an efficient blood draw with a 5 mL syringe, as it would likely cause the blood to hemolyze or clot before the draw is completed.
