Which intervention should a nurse prioritize when caring for an emaciated patient requiring intravenous fluid therapy?

The priority intervention when caring for an emaciated patient requiring intravenous fluid therapy is to stop the insertion procedure if there is a break in technique. This is crucial because maintaining a sterile technique during the insertion of an intravenous catheter is essential to prevent infections. An emaciated patient may already have a compromised immune system due to malnutrition, which makes them more vulnerable to complications, including sepsis from catheter-related infections. Ensuring strict adherence to sterile technique minimizes risks associated with IV therapy, thus enhancing the safety and effectiveness of the intervention.

While other options might seem important, they do not address immediate patient safety during the critical process of IV insertion. Changing the line every 7 days is more related to maintenance rather than the initial placement. The choice of catheter size and flushing the line with saline are important considerations but take a back seat to the fundamental principle of infection control during insertion, particularly for vulnerable patients. Ensuring that the insertion procedure is conducted without any breaks in sterile technique safeguards against potential adverse outcomes that could jeopardize the patient's health.
