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

Choice A rationaleAllowing medications to flow by gravity is a recommended technique for administering medications via a nasogastric tube. It minimizes the risk of tube rupture or patient discomfort from excessive pressure. Using gravity ensures controlled delivery and prevents potential complications associated with forced administration using a syringe.Choice B rationaleCrushing sustained-release tablets is contraindicated because it disrupts the extended-release mechanism, leading to rapid absorption and potential toxicity. Sustained-release formulations are designed to release medication gradually, providing a steady therapeutic effect over time.Choice C rationaleFlushing the tube with only 2 mL of sterile water is inadequate because insufficient flushing may lead to clogging. Typically, 15 to 30 mL of sterile water is recommended after medication administration to maintain patency and ensure the tube remains free of residual debris.Choice D rationaleMixing all medications together is not advised, as it increases the risk of drug-drug interactions and incompatibility reactions. Separating each medication with appropriate flushing between doses ensures therapeutic efficacy and prevents complications such as precipitation or altered drug action.
