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 ensures gradual administration, minimizing the risk of mucosal irritation and preventing excessive pressure or leakage in the nasogastric tube.Choice B rationaleCrushing sustained-release tablets alters their pharmacokinetics, leading to uncontrolled drug release and increased risk of toxicity or subtherapeutic effects. Sustained-release formulations must remain intact.Choice C rationaleUsing 2 mL sterile water is inadequate for flushing a nasogastric tube post-medication; recommended flushing volumes typically range between 10-15 mL for effective clearance.Choice D rationaleMixing medications together may result in chemical interactions and altered bioavailability. Administering each medication individually is essential to maintaining integrity and therapeutic efficacy.
