What instruction should a nurse give to nursing assistive personnel regarding a patient with an intravenous access device?

The appropriate instruction for nursing assistive personnel regarding a patient with an intravenous access device centers around monitoring the IV bag's volume. In this context, notifying the nurse when the IV bag contains less than 100 milliliters is critical because it allows for timely intervention to prevent interruptions in medication delivery or fluid administration. An IV bag that is nearing its end of volume indicates the necessity for a replacement soon to maintain the continuity of care and avoid potential complications, such as air entering the IV line or the patient not receiving the necessary fluids or medications.

Monitoring a threshold of 100 milliliters is practical, as it provides adequate time for the nurse to prepare a new bag and ensures that patient's needs are met without delays. This facilitates proper management of intravenous therapy by ensuring that there is always enough fluid or medication available to the patient.
