Which of the following conditions is a contraindication for taking ibuprofen?

Chronic kidney disease is a contraindication for taking ibuprofen because nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can reduce renal blood flow and impair kidney function further. In patients with pre-existing kidney issues, the use of ibuprofen may exacerbate renal impairment, leading to complications such as fluid retention, hypertension, and even acute kidney injury. Therefore, it is crucial to avoid using ibuprofen in individuals with chronic kidney disease to prevent potential harm to their already compromised renal function.

Other conditions listed, such as asthma, rheumatoid arthritis, and psoriasis, do require cautious use of ibuprofen but are not contraindications. Individuals with asthma may experience exacerbation of symptoms with NSAID use, particularly if they have aspirin-exacerbated respiratory disease, but ibuprofen can still be used with caution under medical supervision. In rheumatoid arthritis, ibuprofen is often used to manage pain and inflammation. Psoriasis may involve treatment with NSAIDs, although caution is warranted since psoriasis can have varied presentations and treatments. Overall, chronic kidney disease stands out as a condition where ibuprofen use would pose significant risks and is thus contraindicated.
