A nurse is providing teaching to an older adult client about methods to promote nighttime sleep.
Which of the following instructions should the nurse include?

Choice A rationale:

Choosing a palpable and straight vein is essential for a successful IV insertion. A vein that is easily palpable and visible helps ensure that the catheter can be inserted smoothly, reducing the risk of complications such as infiltration or extravasation. Additionally, selecting a straight vein makes the insertion process easier and less painful for the client.

Choice B rationale:

Selecting a site on the client's dominant arm is not a requirement for IV insertion. The choice of arm depends on the individual client's condition, vein accessibility, and the healthcare provider's preference. Both arms can be used for IV insertion based on the client's specific needs.

Choice C rationale:

Applying a tourniquet below the venipuncture site helps distend the veins, making them more visible and accessible. This technique can aid in locating suitable veins for insertion. However, it is crucial to release the tourniquet once the vein is accessed to prevent complications such as thrombosis or hematoma.

Choice D rationale:

Elevating the client's arm prior to insertion can cause veins to collapse, making it more challenging to insert the IV catheter. Gravity can assist in distending the veins, so the arm should be positioned at or slightly below the level of the heart during IV insertion to maintain adequate blood flow.
