Question 1

What is the most common cause of gastroesophageal reflux disease (GERD)?

Accepted Answer

Lower esophageal sphincter dysfunction

Answer

The most common cause of Gastroesophageal Reflux Disease (GERD) is dysfunction of the lower esophageal sphincter (LES). The LES is a muscular ring that acts as a valve, normally relaxing to allow food into the stomach and then tightening to prevent stomach acid from flowing back into the esophagus. When the LES is weakened or relaxes inappropriately, stomach contents can reflux, leading to the symptoms and complications associated with GERD.

Question 2

Which of the following is the first-line treatment for mild to moderate ulcerative colitis?

Accepted Answer

Amino salicylates (e.g., mesalamine)

Answer

For patients with mild to moderate ulcerative colitis, aminosalicylates, such as mesalamine, are typically the first-line treatment. These medications work by reducing inflammation in the lining of the colon, helping to induce and maintain remission. They are generally well-tolerated and effective for managing symptoms and preventing disease flares in this patient population.

Question 3

Which of the following is a recommended screening modality for colorectal cancer in average-risk adults aged 50 years or older?

Accepted Answer

Colonoscopy every 10 years

Answer

For average-risk adults aged 50 years or older, a colonoscopy every 10 years is a widely recommended and highly effective screening modality for colorectal cancer. This procedure allows for direct visualization of the entire colon and rectum, enabling the detection and removal of precancerous polyps before they can develop into cancer. Regular screening significantly reduces the incidence and mortality of colorectal cancer.

Question 4

What is the most common cause of chronic pancreatitis in adults?

Accepted Answer

Alcohol use

Answer

In adults, chronic alcohol use is overwhelmingly the most common cause of chronic pancreatitis. Prolonged and heavy alcohol consumption can lead to repeated episodes of acute pancreatitis, which eventually results in irreversible damage to the pancreas, characterized by inflammation, fibrosis, and impaired function. This damage can cause persistent abdominal pain, malabsorption, and diabetes.

Question 5

In patients with irritable bowel syndrome (IBS), which dietary intervention is often recommended to reduce symptoms?

Accepted Answer

Low FODMAP diet

Answer

For patients with irritable bowel syndrome (IBS), a low FODMAP diet is frequently recommended to help reduce symptoms. FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are types of carbohydrates that are poorly absorbed in the small intestine and can ferment in the colon, leading to gas, bloating, and abdominal pain in sensitive individuals. By temporarily restricting and then carefully reintroducing these foods, patients can identify triggers and manage their IBS symptoms more effectively.
