Correct Answer is D
Explanation
Choice A rationale: Furosemide is a loop diuretic used to increase urine output by blocking the reabsorption of sodium and water. It's not typically associated with hyperkalemia. In fact, it's more common for loop diuretics like furosemide to cause hypokalemia (low potassium) due to increased urinary excretion of potassium.
Choice B rationale: Lovastatin is a statin used to lower cholesterol levels. It is not related to increased cholesterol. Additionally, there is no known direct interaction between lovastatin and furosemide. Furosemide is a diuretic, while selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressants, and they do not typically interact in a way that requires discontinuation.
Choice C rationale: Duloxetine is an antidepressant (SNRI), and glipizide is an oral diabetes medication. There's no direct interaction between duloxetine and glipizide that would necessitate discontinuation.
Choice D rationale: Trimethoprim/sulfamethoxazole (Bactrim) is a sulfonamide antibiotic, and glipizide belongs to the sulfonylurea class of medications. Both drugs contain sulfur groups in their chemical structures, and there is a possibility of cross-reactivity or drug interaction. This interaction can potentially reduce the effectiveness of glipizide, leading to compromised blood sugar control. Additionally, sulfonamide antibiotics like trimethoprim/sulfamethoxazole can cause adverse reactions, including skin rashes or hypersensitivity reactions, particularly in individuals sensitive to sulfa medications.
Correct Answer is D
Explanation
Choice A rationale: A breast lump that increases in size before the menstrual period might be related to hormonal changes and is not necessarily indicative of a concerning issue.
Choice B rationale: Bilateral breast nodules that are tender with palpation might be related to benign conditions or hormonal changes.
Choice C rationale: A small, mobile, rubbery breast lump could suggest a benign condition like a fibroadenoma, which might not be as concerning.
Choice D rationale: A breast nodule that is 1 cm in size, nontender, and fixed could potentially raise concerns about malignancy and requires further evaluation.
