This assignment presents a detailed analysis of a case study involving Ms. Candice Tong, a 56-year-old patient admitted to the hospital with peptic ulcers. The analysis identifies significant medication risks stemming from drug-drug interactions between her prescribed medications (warfarin, clarithromycin, esomeprazole, amoxicillin, ramipril, felodipine, atorvastatin, and citalopram) and over-the-counter medications (ibuprofen and St. John's wort). The study highlights the risks associated with concurrent use of citalopram and esomeprazole, as well as atorvastatin with clarithromycin and esomeprazole. The assignment provides nursing actions to mitigate these risks, including dose adjustments, patient monitoring, and patient education about potential adverse effects and the importance of communicating with healthcare providers. The study also addresses the implications of over-the-counter medications and the necessary patient education for safe medication practices before discharge. References are also provided to support the findings.
