Which clinical manifestation of inflammatory bowel disease is common to both patients with ulcerative colitis (UC) and Crohn's disease?
Diarrhea stools
Lesions that penetrate the intestine
Strictures are common
Restricted to rectum
The Correct Answer is A
Choice A rationale
Diarrhea is a common symptom in both ulcerative colitis (UC) and Crohn's disease, often presenting with urgency and frequency.
Choice B rationale
Lesions that penetrate the intestine are more characteristic of Crohn's disease, which can affect any layer of the intestinal wall and any part of the gastrointestinal tract.
Choice C rationale
Strictures are more common in Crohn's disease due to its transmural inflammatory nature, which can lead to fibrosis and narrowing of the intestines¹.
Choice D rationale
UC is restricted to the colon and often involves the rectum, but Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus and is not restricted to the rectum¹.

Correct Answer is C
Explanation
Choice A rationale
Congestive heart failure is not directly associated with an increased risk of developing acute pancreatitis. While it can contribute to overall health deterioration, it does not cause the condition.
Choice B rationale
Emphysema primarily affects the lungs and does not increase the risk of acute pancreatitis. It is a chronic obstructive pulmonary disease and is unrelated to pancreatic function.
Choice C rationale
Alcohol abuse is a well-known risk factor for acute pancreatitis. It can lead to repeated episodes of inflammation in the pancreas, which can eventually become chronic and lead to acute pancreatitis.
Choice D rationale
Diabetes mellitus is a result of chronic pancreatitis or can be a comorbidity, but it is not a direct cause of acute pancreatitis. However, it can be associated with complications related to the pancreas.
Correct Answer is B
Explanation
Choice A rationale
Potassium levels are not directly affected by lactulose. While cirrhosis can lead to imbalances in electrolytes, including potassium, lactulose is not used to manage potassium levels in the bloodstream.
Choice B rationale
Ammonia is produced by the breakdown of proteins in the intestines and is normally processed by the liver. In cirrhosis, the liver's ability to convert ammonia to urea is impaired, leading to increased levels in the blood. Lactulose helps reduce blood ammonia levels by converting it into ammonium, which is then excreted.
Choice C rationale
Bicarbonate levels are related to the body's pH balance and are not the target of lactulose treatment. Cirrhosis does not typically result in bicarbonate imbalances that would be treated with lactulose.
Choice D rationale
Glucose levels are managed by insulin and other metabolic processes, not lactulose. While cirrhosis can affect overall metabolism, lactulose does not have a direct effect on blood glucose levels.
