DaVita Competency Practice Exam 2025 – Complete Prep Guide

Rotating needle sites is a recommended practice for reducing the risk of complications during medical procedures, particularly in the context of vascular access, such as dialysis. Frequent use of the same site can lead to local complications including inflammation, infection, and thrombosis, which can compromise blood flow and increase the risk of vascular complications, such as aneurysms.

By utilizing different needle sites, healthcare providers can minimize trauma to the blood vessels, promote better healing, and reduce the stress placed on any one area of the vascular access. This proactive approach not only helps maintain the integrity of the access site but also promotes the overall safety and effectiveness of the treatment.

The other options presented do not align with best practices for keeping vascular access safe. Increasing sodium intake is not relevant to the prevention of aneurysms and could potentially harm a patient, especially those with certain health conditions. Using high-potassium solutions can pose a risk of hyperkalemia, which is particularly dangerous for patients undergoing dialysis, and skipping treatments is counterproductive to managing chronic conditions effectively and increases overall health risks.
