Final answer:
A 60-year-old woman with a smoking history of 20 pack-years presents with symptoms indicative of a duodenal ulcer, which can be influenced by her lifestyle choices and medication use. Smoking and persistent use of ibuprofen are particularly relevant for making a differential diagnosis. Upon diagnosis, treatment may involve antacids and antibiotics, with consideration for potential medication side effects and interactions.
Step-by-step explanation:
Pack Year History and Differential Diagnosis
The pack year history for the 60-year-old female patient who has smoked one pack of cigarettes per day for 20 years is 20 pack-years. This is calculated by multiplying the number of packs of cigarettes smoked per day by the number of years the person has smoked.
Factors for Differential Diagnosis
The factors to consider in making a differential diagnosis include her symptoms of epigastric pain, bloating and fullness, the temporal relationship of the pain to meals, relief with antacids, smoking history, alcohol consumption, chronic use of ibuprofen, and family history of an ulcer. Her current medications, lisinopril for hypertension and Unidur for COPD, should also be considered.
Drug Therapy for Duodenal Ulcer
When the patient is diagnosed with a duodenal ulcer following endoscopy, the advantages of drug therapy might include symptom relief through antacids and the healing of ulcers with the avoidance of NSAIDs or the treatment of H. pylori infection with antibiotics. Disadvantages may include side effects from medications, potential interactions with her current medications, and recurrence if underlying issues such as smoking and NSAID use are not addressed.
