"Strictureplasty is commonly performed in the treatment of Crohn's disease."

Answer and Explanation

The Correct Answer is D

A. Strictureplasty is a surgical procedure, not a non-surgical procedure. It is used to treat strictures by widening them, typically in the gastrointestinal tract.
B. Strictureplasty does not remove strictures but rather works to widen or repair the narrowed areas, allowing for improved passage through the affected part of the gastrointestinal tract.
C. Strictureplasty is not used to repair fractures in bones. It is specifically used in the gastrointestinal system to treat strictures.
D. Strictureplasty is commonly performed in the treatment of Crohn's disease, particularly in cases where the disease causes strictures in the intestines. It is a procedure that can help maintain the integrity of the intestine by widening narrowed areas without the need for resection.

Correct Answer is C

Explanation

A. Hypermagnesemia is not typically associated with refeeding syndrome. In fact, hypomagnesemia is more common due to the rapid shift of electrolytes and the body's increased demand during refeeding.
B. Hyponatremia is not a hallmark of refeeding syndrome. This condition more commonly leads to electrolyte imbalances like hypophosphatemia, hypokalemia, and hypomagnesemia rather than low sodium levels.
C. Hypophosphatemia is a hallmark finding in refeeding syndrome. As the body shifts from catabolic to anabolic states during refeeding, phosphorus is rapidly used in cellular processes, and its levels drop, which can lead to muscle weakness, respiratory failure, and other complications.
D. Hyperkalemia is not typically associated with refeeding syndrome. The condition is more likely to cause hypokalemia due to the shift of potassium into cells during the anabolic process after refeeding.

A. An intolerance to the feedings B. Esophageal perforation with fistula formation into the lung C. Extension of the tumor into the aorta D. Leakage of fluids into the mediastinum

Correct Answer is B

Explanation

A. An intolerance to the feedings might cause discomfort, but it would not typically cause increasing pain, fever, and dyspnea. These symptoms are more indicative of a serious complication.
B. Esophageal perforation with fistula formation into the lung is the most likely cause of these symptoms. A perforation can lead to leakage of gastric contents into the pleural space or mediastinum, causing fever, pain, and respiratory distress. The formation of a fistula between the esophagus and the lung would lead to dyspnea.
C. Extension of the tumor into the aorta is a rare complication that would typically manifest with symptoms related to cardiovascular issues, not gastrointestinal symptoms like fever and dyspnea.
D. Leakage of fluids into the mediastinum is a possible cause of the symptoms, but esophageal perforation with a fistula into the lung is more directly linked to these specific symptoms, especially dyspnea.
