A nurse is caring for a client who has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

Choice A rationale This explanation describes the mechanism of extended-release or sustained-release medications rather than enteric-coated tablets. Enteric coating is designed to resist dissolution in the acidic environment of the stomach and instead dissolve in the more alkaline environment of the small intestine. While crushing some medications causes a rapid release of the entire dose, the primary scientific concern with enteric-coated aspirin is the loss of gastric protection rather than the specific rate of systemic absorption. Choice B rationale Crushing an enteric-coated tablet does not destroy the active pharmacological ingredients of the aspirin itself; rather, it alters the physical delivery system. The aspirin remains chemically active but loses its protective outer layer. Claiming the ingredients are destroyed is scientifically inaccurate. The primary issue is that the medication will now exert its effects in the wrong part of the gastrointestinal tract, potentially leading to adverse local effects on the gastric mucosa that the coating was intended to prevent. Choice C rationale Suggesting that the nurse can crush enteric-coated medication and mix it with food is incorrect and potentially harmful. Crushing these tablets bypasses the intended safety mechanism, exposing the stomach lining to the irritating effects of aspirin. This can lead to gastritis or peptic ulcers. The nurse should never encourage altering a medication's form if it is specifically formulated with an enteric coat, as this violates standard pharmacological principles and safe medication administration practices for the client. Choice D rationale Enteric coating is specifically applied to aspirin to protect the gastric mucosa from direct irritation and to prevent the drug from being deactivated by stomach acid. If the coating is crushed, the aspirin is released prematurely in the stomach, significantly increasing the risk of gastric irritation, dyspepsia, and indigestion. Explaining this risk helps the client understand that the coating is a safety feature intended to prevent gastrointestinal discomfort and potential injury like ulcers or bleeding.
