Which statement is TRUE regarding a nurse's role in maintaining peripheral intravenous catheters?

The statement regarding the documentation of all IV bags being time taped to ensure they run on time is accurate and reflects a critical practice in IV therapy management. Time taping helps ensure that the infusion of medication or fluids proceeds as scheduled, which is crucial for patient safety and effective treatment. By marking the bag with a time indicator, it allows nurses to visually assess when the IV bag is due to be replaced or when it will run out, helping to prevent interruptions in therapy.

Proper timing is especially important in scenarios where medication levels must be maintained, as fluctuations can lead to complications or suboptimal therapeutic effects. Such diligence is part of the nurse's responsibility to monitor and manage IV therapies effectively, ensuring both the safety of the patient and the efficiency of care.

In the context of the other statements, while they may relate to IV therapy in varying degrees, they do not align with standard practices. For instance, proper documentation typically involves more than just the nurse’s name, and the choice of insertion sites often depends on patient needs and the specific therapy being provided. Additionally, using a larger gauge needle isn't a blanket requirement; the choice of gauge should be based on the type of therapy, which varies widely from hydration to specific medication administration.
