When educating a patient on the use of ketorolac, the nurse should emphasize which important cautionary instruction?

A. Avoid using NSAIDs if experiencing fever: NSAIDs like ketorolac are intended to reduce fever, so avoiding them solely because of fever is inappropriate. Fever itself is not a contraindication for use unless there are other clinical concerns. B. Inform the healthcare provider about concurrent use with other medications: Ketorolac can interact with other medications, including anticoagulants, other NSAIDs, and certain antihypertensives, increasing the risk of bleeding, kidney damage, or reduced therapeutic effect. Patients should always inform their provider of all medications and supplements before and during treatment. C. Take NSAIDs on an empty stomach to enhance absorption: Taking ketorolac on an empty stomach increases the risk of gastrointestinal irritation, ulceration, or bleeding. NSAIDs are generally advised to be taken with food or a full glass of water to minimize GI side effects. D. Take half the prescribed dosage to avoid complications associated with the drug: Altering the prescribed dose without consulting a healthcare provider can lead to inadequate pain control or increased risk of adverse effects. Dosage changes should only be made under medical guidance.
