Sample ABIM - American Board of Internal Medicine Practice Questions
Try these questions from our free ABIM - American Board of Internal Medicine practice tests. The correct answer and an explanation follow each question.
Antimicrobial medications and bismuth should be avoided for ____ before testing in order to increase the diagnostic precision of the urea breath test and fecal antigen test.
- A. plavix
- B. 4.5 cm
- C. 28 days
- D. q0.5-1y
Answer: C. 28 days
To improve the diagnostic accuracy of the urea breath test and fecal antigen test for detecting Helicobacter pylori infection, antimicrobial agents and bismuth should be avoided for 28 days before testing. These substances can interfere with the accuracy of the tests and may lead to false-negative results. It is important to withhold any antibiotics, proton pump inhibitors (PPIs), bismuth-containing medications, and other medications that can suppress or eradicate H. pylori during this period to ensure accurate test results. The specific duration of avoidance may vary depending on the specific test being used and the recommendations of the healthcare provider. It's always best to consult with a healthcare professional for specific instructions regarding medication and dietary restrictions before undergoing H. pylori diagnostic testing.

- A. Fasting glucose tolerance test
- B. ACTH stimulation test
- C. 24-hour urinary free cortisol
- D. Dexamethasone suppression test
Answer: B. ACTH stimulation test
