The charge nurse observes a new nurse demonstrate the administration of two different liquid medications through a gastrostomy tube used for continuous feedings, as seen in the video. Which action(s) should the charge nurse take? (Select all that apply)

A. The tube should be flushed with at least 15–30 mL of water before, between, and after medication administration to prevent clogging and ensure full delivery of the medications. B. Instructing the nurse to administer each medication separately is correct. This is important to prevent drug interactions within the tube and to ensure accurate dosing. Administering medications separately allows for proper absorption and can prevent complications such as clogging of the tube. C. Adding the liquid volumes when documenting fluid intake is correct. It is essential to account for all sources of fluid intake to maintain accurate fluid balance records. Medications administered through a gastrostomy tube contribute to the patient's overall fluid intake and must be included in the documentation. D. Confirming that the nurse determined the amount of gastric residual is correct. This is a critical step to ensure that the patient is tolerating the feedings and to prevent complications such as aspiration. Gastric residual volume can indicate if the patient's digestive system is processing the feeding appropriately. E. Advising the nurse to use the plunger when giving medications is not necessary in this context. The use of a plunger can be appropriate in some situations, but the scenario does not provide enough information to suggest that the nurse had difficulty administering the medications that would require the use of a plunger. Additionally, using a plunger can increase the risk of tube damage or patient discomfort.
