A nurse is teaching about preventative measures to a female client who has chronic urinary tract infections.
Which of the following instructions should the nurse include in the teaching?

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.

The correct answer is **b. A room containing personal belongings.**

Choice A rationale:

A room without a window would not be a therapeutic environment for a cognitively impaired client. Lack of natural light and connection to the outside world can be disorienting and distressing for these patients.

Choice B rationale:

A room containing personal belongings is the most therapeutic environment for a cognitively impaired client. Familiar objects and surroundings can help provide a sense of comfort, security, and orientation. This can reduce agitation and confusion, which are common issues for cognitively impaired patients.

Choice C rationale:

A room adjacent to the nursing station may not be the most therapeutic environment. While proximity to staff can be beneficial, the increased noise and activity level near the nursing station could be overstimulating and disruptive for a cognitively impaired client.

Choice D rationale:

A room with dim lighting is not ideal for a cognitively impaired client. Adequate lighting is important to help these patients maintain orientation and avoid falls or other safety issues. Dim lighting can contribute to confusion and disorientation.
