Hypokalemia is often associated with which one of the following conditions?
Metabolic acidosis
Metabolic alkalosis
Hyperchloremia
None of the above
The Correct Answer is B
A. Metabolic acidosis is characterized by a low pH and a decrease in bicarbonate, but it is not typically associated with hypokalemia. In fact, acidosis may cause potassium to shift out of cells, increasing serum potassium levels.
B. Metabolic alkalosis is often associated with hypokalemia because the body compensates for alkalosis by shifting potassium into cells, leading to a lower serum potassium level. This is commonly seen with conditions like vomiting or the overuse of diuretics.
C. Hyperchloremia refers to elevated chloride levels, which may be associated with metabolic acidosis, but it is not directly linked to hypokalemia.
D. "None of the above" is incorrect because metabolic alkalosis is a known condition associated with hypokalemia.

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 C
Explanation
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.
