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 C
Explanation
A. Weakness, vomiting, hypotension, and mental confusion may occur in cases of diabetic ketoacidosis (DKA), but these are more acute signs of severe complications rather than early symptoms of type 1 diabetes.
B. Vomiting, abdominal pain, sweet fruity breath, dehydration, and Kussmaul breathing are signs of diabetic ketoacidosis (DKA), a serious complication that typically develops after the onset of type 1 diabetes, not early symptoms.
C. Polydipsia (excessive thirst), polyuria (frequent urination), polyphagia (excessive hunger), weight loss, and fatigue are classic early signs and symptoms of type 1 diabetes due to the body's inability to regulate blood glucose levels properly.
D. Recurrent infections, visual changes, and paresthesia (numbness or tingling) are typically associated with long-term, poorly controlled diabetes, not early signs of type 1 diabetes.
Correct Answer is D
Explanation
A. Dark-colored urine is typically a sign of dehydration, as the kidneys concentrate the urine when the body is low on water. Adequate hydration usually results in lighter-colored urine.
B. Strong-smelling urine can indicate dehydration, certain foods, or medications, but it is not an indicator of adequate hydration. Properly hydrated urine typically has a mild odor.
C. Oliguria, or low urine output, can be a sign of dehydration, kidney dysfunction, or other underlying issues. It is not a sign of adequate hydration.
D. Pale-colored urine is a characteristic of adequate hydration. When the body is well-hydrated, the kidneys excrete a greater volume of diluted urine, which tends to be light in color.
