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 B
Explanation
Choice A Reason:
Shoe covers are used to protect the shoes and prevent the spread of contaminants from one area to another. They are not specifically required for droplet precautions during blood glucose monitoring. Droplet precautions typically focus on protecting mucous membranes of the eyes, nose, and mouth from droplet spatter.
Choice B Reason:
Masks are essential when dealing with patients under droplet precautions. Droplets can transmit infections when a person coughs, sneezes, or talks, and a mask provides a barrier that prevents the inhalation of these potentially infectious droplets. For procedures like blood glucose monitoring, where close contact with the patient is necessary, wearing a mask is crucial to protect both the healthcare worker and the patient.
Choice C Reason:
A gown is used to protect the healthcare worker's skin and clothing from contamination with potentially infectious material. While it is an important piece of personal protective equipment, it is not the primary requirement for droplet precautions in the context of blood glucose monitoring, unless there is a risk of substantial splashing or spraying of bodily fluids.
Choice D Reason:
Goggles are used to protect the eyes from splashes of blood or other body fluids. They are important in procedures where there is a risk of splashing, but for blood glucose monitoring, the risk is minimal. Therefore, goggles are not the primary piece of equipment required for droplet precautions in this scenario.
Correct Answer is A
Explanation
Choice A Reason:
When a patient is under "Contact Precautions," it is recommended that healthcare workers don a gown upon entering the patient's room. This is to prevent the spread of infection through contact with the patient or their environment. The gown should be removed before leaving the room to avoid contaminating other areas.
Choice B Reason:
While a face shield may be necessary for certain procedures, it is not specifically required for "Contact Precautions." The primary concern with contact precautions is preventing the transmission of infections through touch, not through droplets, which is what a face shield would protect against.
Choice C Reason:
Donning a mask is not a standard requirement for "Contact Precautions" unless there is a risk of droplet transmission. In this scenario, the precautions are specifically for contact, and therefore, a mask alone would not be sufficient.
Choice D Reason:
Gloves should be donned before any potential contact with the patient or their immediate environment, not just after cleaning and evaluating the venipuncture site. Gloves are a critical component of PPE when dealing with patients under "Contact Precautions."
