Which of the following is used to stabilize a patient's arm during a venipuncture?
Arm restraints
A blood pressure cuff
A phlebotomy wedge
A phlebotomy cart
The Correct Answer is C
Choice A Reason:
Arm restraints are typically used to prevent patients from moving, particularly in pediatric or psychiatric settings where the patient may not voluntarily keep still. However, they are not specifically designed for stabilizing the arm during venipuncture procedures.
Choice B Reason:
A blood pressure cuff can be used as a substitute for a tourniquet to engorge the veins before venipuncture, but it is not designed to stabilize the arm during the procedure. Its primary function is to measure blood pressure, not to provide stability.
Choice C Reason:
A phlebotomy wedge is a device specifically designed to support and stabilize a patient's arm during venipuncture. It helps to maintain the arm in a comfortable and steady position, which can be particularly helpful for patients with tremors or for those who have difficulty holding their arm still.
Choice D Reason:
A phlebotomy cart is used to transport and organize phlebotomy supplies. While it is an essential piece of equipment for a phlebotomist, it does not play a role in stabilizing a patient's arm during venipuncture.

Correct Answer is B
Explanation
Choice A Reason:
Submitting laboratory results to the representative for workers' compensation is generally not a violation of patient privacy. This action is often necessary as part of the claims process and is typically done with the patient's consent or as mandated by law.
Choice B Reason:
Discussing laboratory results with a patient's partner without the patient's explicit consent is a violation of patient privacy. Confidentiality is a fundamental principle in healthcare, and disclosing health information to unauthorized individuals, including family members, breaches that confidentiality.
Choice C Reason:
Providing diagnosis codes to a patient's insurance company is a standard procedure and is not considered a violation of patient privacy. This information is necessary for the insurance company to process claims and provide coverage for medical services.
Choice D Reason:
Printing a patient's full name on the specimen label is standard practice and does not violate patient privacy. This is done to ensure that the specimen is correctly identified and matched to the patient, which is critical for accurate diagnosis and treatment.
Correct Answer is A
Explanation
Choice A Reason:
Anchoring a vein is a technique used to stabilize the vein during venipuncture to prevent it from rolling. The recommended practice is to anchor the vein 1 to 2 inches below the puncture site. This is done by applying gentle traction on the skin downward with the thumb, which helps to stabilize the vein and facilitate the insertion of the needle.
Choice B Reason:
Anchoring 1 to 2 inches above the puncture site is not the standard practice. This position would not provide the necessary tension on the vein to prevent it from rolling and could make the venipuncture more difficult.
Choice C Reason:
Anchoring 2 inches left of the puncture site does not provide the correct angle or tension for stabilizing the vein for a venipuncture and is not a recommended technique.
Choice D Reason:
Anchoring 1 inch right of the puncture site is also not a recommended practice. Similar to anchoring to the left, this does not provide the proper stabilization needed for a successful venipuncture.
