Free ACG Publications Questions and Answers — Questions and Answers
Question 1: According to the ACG guidelines, at what age should average-risk individuals begin screening for colorectal cancer?
- 40
- 45 (Correct answer)
- 50
- 55
Correct answer: 45
The ACG, along with other major medical societies, updated its guidelines to recommend that average-risk individuals begin colorectal cancer screening at age 45. This change was implemented due to a rising incidence of colorectal cancer in younger populations. Early screening helps detect and prevent cancer more effectively.
Question 2: Which of the following is considered the first-line treatment for gastroesophageal reflux disease (GERD) according to ACG guidelines?
- H2 receptor antagonists
- Proton pump inhibitors (PPIs) (Correct answer)
- Antacids
- Surgery
Correct answer: Proton pump inhibitors (PPIs)
Proton pump inhibitors (PPIs) are considered the most effective first-line treatment for gastroesophageal reflux disease (GERD) according to ACG guidelines. PPIs provide superior and more sustained acid suppression compared to H2 receptor antagonists, leading to better symptom control and healing of erosive esophagitis. They are crucial for managing moderate to severe GERD symptoms.
Question 3: According to ACG guidelines, what is the recommended first-line therapy for H. pylori eradication?
- Triple therapy with PPI, amoxicillin, and clarithromycin (Correct answer)
- Bismuth quadruple therapy
- Metronidazole and tetracycline
- H2 receptor antagonists and clarithromycin
Correct answer: Triple therapy with PPI, amoxicillin, and clarithromycin
ACG guidelines recommend triple therapy consisting of a proton pump inhibitor (PPI), amoxicillin, and clarithromycin as a first-line regimen for H. pylori eradication. This combination is effective in regions with low clarithromycin resistance and for patients without prior macrolide exposure. The PPI reduces gastric acid, while the antibiotics target and eliminate the H. pylori bacteria.
Question 4: Which of the following medications is typically used as a first-line treatment for inducing remission in mild-to-moderate ulcerative colitis?
- Methotrexate
- Mesalamine (Correct answer)
- Azathioprine
- Infliximab
Correct answer: Mesalamine
For inducing remission in mild-to-moderate ulcerative colitis, mesalamine (an aminosalicylate) is typically the first-line treatment according to ACG guidelines. Mesalamine works by reducing inflammation in the colon, directly targeting the affected area. It is effective for many patients with less severe disease, helping to control symptoms and promote mucosal healing.
Question 5: What is the most common cause of chronic liver disease in the United States, according to ACG data?
- Alcoholic liver disease
- Hepatitis C
- Hepatitis B
- Nonalcoholic fatty liver disease (NAFLD) (Correct answer)
Correct answer: Nonalcoholic fatty liver disease (NAFLD)
Nonalcoholic fatty liver disease (NAFLD) has become the most common cause of chronic liver disease in the United States, according to ACG data. Its prevalence is rapidly increasing due to the rising rates of obesity, type 2 diabetes, and metabolic syndrome. NAFLD can progress to more severe liver conditions like cirrhosis and liver cancer, making it a significant public health concern.
