Final answer:
The charge nurse should ensure that the plan of care includes the intervention of flushing the NG tube every 8 hours with 0.9% sodium chloride irrigation to maintain tube patency and prevent clogging.
Step-by-step explanation:
The charge nurse should ensure that the plan of care includes the intervention of flushing the NG tube every 8 hours with 0.9% sodium chloride irrigation. This helps to maintain tube patency and prevent clogging. Using an acidic juice to unclog a blocked tube is not recommended as it can cause further irritation to the GI tract. Adding dissolved medications to the enteral feeding should be avoided to ensure accurate dose delivery. Using a 60-mL syringe to flush out a clogged tube is also not recommended as it can create excessive pressure and lead to tube dislodgment.
