Why is Crohn disease more likely to cause intestinal obstruction than ulcerative colitis?
Crohn disease is located in the small intestine
Crohn disease is exacerbated by certain foods, such as spicy foods
Crohn disease causes granulomas to form in the submucosal layers
Crohn disease causes abdominal pain and watery diarrhea
The Correct Answer is C
A. While Crohn disease can affect any part of the gastrointestinal tract, it often affects the small intestine, particularly the ileum. However, the location alone does not explain the increased risk of obstruction.
B. Certain foods, such as spicy foods, may exacerbate symptoms of Crohn disease, but this is not the primary reason it causes intestinal obstruction.
C. Crohn disease causes inflammation that can lead to the formation of granulomas, particularly in the submucosal layers. These granulomas contribute to fibrosis and narrowing of the bowel, which can lead to intestinal obstruction. This is a key feature of Crohn disease that makes it more likely to cause obstruction compared to ulcerative colitis.
D. Abdominal pain and watery diarrhea are common symptoms of both Crohn disease and ulcerative colitis, but they are not directly related to the increased risk of obstruction in Crohn disease.

Correct Answer is A
Explanation
A. Meconium ileus is a common early sign of cystic fibrosis in newborns. It occurs when the meconium, which is the first stool of a newborn, becomes thick and sticky, leading to a blockage in the intestines. This is often one of the first signs of cystic fibrosis in infants.
B. Cyanosis, while indicative of oxygenation problems, is not a specific sign of cystic fibrosis in newborns. It may be seen in many respiratory or cardiac conditions.
C. Yellow, seedy, loose stools are more commonly associated with normal newborn digestion or conditions like lactose intolerance or gastrointestinal infections, not specifically cystic fibrosis.
D. Coughing is a symptom of cystic fibrosis, but it typically develops later as the disease progresses and affects the lungs, rather than being an early sign in newborns.
Correct Answer is B
Explanation
A. Overactive bladder refers to the condition where there is a sudden and uncontrollable urge to urinate, often associated with urgency and frequency, but it is not caused by exertional stimuli.
B. Stress incontinence is the type of urinary incontinence that occurs when physical activity or exertion, such as coughing, sneezing, laughing, or lifting, increases abdominal pressure and leads to involuntary leakage of urine.
C. Functional incontinence refers to the inability to reach the bathroom in time due to physical or cognitive impairments, such as mobility issues or dementia, rather than exertional triggers.
D. Urge incontinence is the sudden and intense urge to urinate, often leading to involuntary loss of urine. It is not typically caused by exertion but by an overactive bladder.
