Final answer:
CNAs provide fluids to a resident with a catheter by preparing an IV solution through a process of dilution calculation to achieve the proper concentration, ensuring proper aseptic techniques to prevent infections.
Step-by-step explanation:
The best way for a Certified Nursing Assistant (CNA) to provide fluid to a resident with a catheter, particularly for patients who are dehydrated and require fluids intravenously, is by preparing and administering an IV solution. This involves using a sterile solution from an IV bag and combining it with a more concentrated, sterile stock solution, like Potassium Chloride (KCl). The CNA must carefully perform a dilution calculation to achieve the correct concentration of the solution before administration. It is essential to maintain strict aseptic techniques to prevent the risk of catheter-related bloodstream infections, which are serious and potentially life-threatening.
The CNA should draw up some stock solution using a syringe and inject it into the waiting IV bag, diluting it to the proper concentration. This ensures that the resident receives the necessary fluids safely and accurately.
