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

A. Advising the nurse to use the plunger when giving medications is not recommended as it can create too much pressure and potentially damage the gastrostomy tube or cause discomfort to the patient. It's important to allow the medication to flow by gravity to prevent these issues. B. Encouraging the nurse to flush the tube with more water is correct because it helps to ensure that the medication is cleared from the tube and reduces the risk of clogging. Flushing with water also helps to maintain hydration for the patient. C. Confirming that the nurse determined the amount of gastric residual is correct because it is essential to check for any undigested food or medication in the stomach before administering more. This helps to prevent aspiration and other complications. D. Instructing the nurse to administer each medication separately is correct. This practice prevents drug interactions within the tube and ensures that each medication is given correctly and has the intended effect. E. Adding the liquid volumes when documenting fluid intake is correct because all fluids administered, including medications, should be accounted for in the patient's fluid balance. This is crucial for monitoring and managing the patient's hydration status and overall health.
