A nurse is mentoring a new nurse who is learning to start IVs. The nurse tells the new nurse that in case the patient needs subsequent venipuncture sites, the best place to initially start an IV is the:
most appropriate distal vein on the nondominant arm.
most appropriate proximal vein available on either arm.
antecubital vein of the patient's nondominant arm.
antecubital vein of the patient's dominant arm.
The Correct Answer is A
A. Distal veins, such as those in the hand or forearm of the nondominant arm, are often preferred for initial IV placement. These veins are typically smaller but can be easier to access and cause less discomfort for the patient compared to more proximal veins.
B. Proximal veins, such as those in the upper arm (brachial or basilic veins), may be considered if distal veins are not accessible or suitable. However, proximal veins are larger and can be more difficult to cannulate, potentially causing more discomfort and increasing the risk of complications.
C. The antecubital veins, located in the bend of the elbow, are commonly used for venipuncture due to their accessibility and size. The antecubital vein of the nondominant arm is often preferred to minimize interference with the patient's daily activities and reduce the risk of complications associated with frequent use of the dominant arm.
D. While the antecubital vein of the dominant arm may also be accessible, it is generally recommended to preserve this area for procedures that require a higher level of dexterity and strength. Frequent venipuncture in the dominant arm can lead to discomfort and potential complications, such as phlebitis or thrombosis.

C. This method is recommended because it is less painful, as the sides of the fingertips have fewer nerve endings compared to the pads or 'balls' of the fingers.
A. Avoiding the use of the thumbs is not necessary unless they are calloused or used frequently for other tasks that could affect sensitivity.
B. Avoiding the use of the dominant hand's fingers are not necessary unless they are calloused or used frequently for other tasks that could affect sensitivity.
D. Using the ball of the finger is not recommended for blood glucose monitoring because it can be more painful and may lead to less blood flow, resulting in difficulty obtaining an adequate blood sample.
