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 rationaleFlushing the tube with only 2 ml of sterile water after administering all medications may not be sufficient to ensure the tube is completely clear. The recommended amount is usually more to ensure the tube is adequately flushed.Choice B rationaleAllowing medications to flow into the tube by gravity is the correct method as it helps to ensure that the medications are delivered at a consistent rate without the risk of pushing too fast.Choice C rationaleCrushing sustained-release tablets is contraindicated as it can alter the medication's release properties, leading to potential overdose or loss of efficacy.Choice D rationaleMixing all medications together prior to administration can cause interactions and alter the effectiveness or stability of the medications, which is not recommended.
