What is the correct instruction for a patient when administering an enteric-coated tablet?

The correct instruction for a patient when administering an enteric-coated tablet is to swallow the tablet whole with a glass of water. This is essential because enteric-coated tablets are specifically designed to resist dissolution in the acidic environment of the stomach and instead dissolve in the more alkaline intestine. Crushing the tablet, as suggested in one option, would destroy the enteric coating and potentially lead to stomach irritation or reduced effectiveness of the medication. Placing the tablet under the tongue would not be appropriate as this method is typically used for medications meant to be absorbed sublingually. While some medication absorption can be affected by food, enteric-coated tablets should not necessarily be taken with food, as this could interfere with the coating's intended function. Therefore, swallowing the tablet whole with water is critical in ensuring that the medication is released exactly where it’s intended to work.
