A nurse is preparing to administer ketorolac to a client. Which of the following conditions should the nurse include as a contraindication for taking this medication?

A. History of gastrointestinal bleeding: Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can inhibit prostaglandin synthesis, increasing the risk of gastrointestinal bleeding or ulceration. A history of GI bleeding is a contraindication due to the heightened risk of serious complications. B. Liver impairment: While caution is warranted, mild to moderate liver impairment is not an absolute contraindication. Liver function should be monitored, but it does not automatically prevent ketorolac use. C. Allergy to codeine: Ketorolac is not an opioid and does not contain codeine. An allergy to codeine does not contraindicate its administration. D. History of glaucoma: Ketorolac does not typically affect intraocular pressure or exacerbate glaucoma. It is not contraindicated in clients with this condition.
