A nurse is caring for a client who reports a headache and has a history of a peptic ulcer. Which of the following medications should the nurse administer?

A) Ketorolac: Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID) often used for severe pain. However, it can cause gastrointestinal irritation and bleeding, which poses a significant risk for a client with a history of peptic ulcers. Therefore, administering ketorolac would not be advisable in this situation. B) Acetaminophen: Acetaminophen is an analgesic that does not have the gastrointestinal side effects associated with NSAIDs. It is a safer option for clients with a history of peptic ulcers, as it does not irritate the stomach lining and can effectively relieve headache pain without exacerbating ulcer-related complications. C) Aspirin: Aspirin is another NSAID that can increase the risk of gastrointestinal bleeding, especially in individuals with a history of peptic ulcers. While it is effective for pain relief, its anticoagulant properties and irritation potential make it an unsuitable choice for this client. D) Ibuprofen: Like other NSAIDs, ibuprofen can cause gastrointestinal issues, including irritation and bleeding. Given the client’s history of peptic ulcers, using ibuprofen could lead to exacerbation of the condition and should be avoided in favor of safer alternatives for pain management.
