Final answer:
If the nurse notes precipitates in the IV tubing, they should stop the infusion, change the tubing, and continue to monitor the infusion site.
Step-by-step explanation:
If the nurse notes precipitates in the IV tubing during the administration of multiple infusions into a single intravenous access, the appropriate action is to stop the infusion. Precipitates in the IV tubing can cause obstruction and potentially harm the patient. Therefore, it is important to discontinue the infusion and assess the situation.
After stopping the infusion, the nurse can examine the IV tubing for the presence of precipitates. If any precipitates are observed, the tubing should be changed. This ensures that the new tubing is free from debris or particles that may have contributed to the formation of precipitates in the first place.
Once the new tubing is in place, the nurse can restart the infusion at an appropriate rate, considering the patient's condition and the prescribed dosage. It is crucial to monitor the infusion site carefully to ensure that no further precipitates develop.
