A nurse is preparing to administer medications to a child via a nasogastric tube. Which of the following actions should the nurse take?

A. Crushing sustained-release tablets is not recommended because it can alter the medication's intended effect, releasing it all at once, which can be dangerous for the child. B. Allowing medications to flow into the tube by gravity is the correct method. It ensures the medication is delivered slowly and effectively, preventing the tube from clogging and ensuring proper absorption. C. Flushing the tube with 2 mL of sterile water is insufficient after all medications are administered. Typically, the tube should be flushed with 15-30 mL of water before and after medication administration to ensure patency. D. Mixing all medications together is not recommended because different medications may have incompatible properties, and mixing them could alter their effectiveness or cause adverse reactions. Each medication should be administered separately.
