A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion.

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.

The client weighs 80 kg. The nurse should set the IV infusion to deliver how many mL/hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies.)

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.

Choice A rationale:

Wearing clothing with zippers instead of buttons does not address the safety concerns related to Alzheimer's disease. This choice does not ensure the client's safety or prevent wandering, which are common issues in Alzheimer's patients.

Choice B rationale:

Placing locks at the tops of exterior doors is essential for the safety of clients with Alzheimer's disease. Alzheimer's patients often have a tendency to wander and may become disoriented, putting them at risk of getting lost or injured outside the home. Proper locks can prevent them from leaving the house unsupervised.

Choice C rationale:

Replacing the carpet with hardwood floors may reduce the risk of falls but does not specifically address the safety concerns related to Alzheimer's disease. It is important to focus on measures that prevent wandering and ensure the client's safety in various situations.

Choice D rationale:

Encouraging physical activity prior to bedtime is a good practice for promoting sleep in older adults but does not directly address the safety concerns of Alzheimer's patients. Safety measures, such as securing doors, supervising the client, and preventing wandering, are more crucial in this context.
