Evidence supports probiotic use (especially Saccharomyces boulardii and Lactobacillus) for reducing antibiotic-associated and C. difficile diarrhea.
A patient with celiac disease must strictly avoid which protein?
Answer: Gluten
Gluten, found in wheat, barley, and rye, triggers the autoimmune response that damages intestinal villi in celiac disease.
Short bowel syndrome most commonly results in malabsorption of which nutrient class?
Answer: Fat-soluble vitamins and long-chain fatty acids
Fat absorption requires adequate small bowel surface area; short bowel syndrome leads to fat and fat-soluble vitamin malabsorption.
Which finding best indicates refeeding syndrome in a malnourished patient starting nutritional support?
Answer: Hypophosphatemia
Refeeding syndrome is characterized by dangerous hypophosphatemia as phosphate shifts into cells during carbohydrate metabolism.
A patient with pancreatitis who is transitioning from NPO to oral feeds should begin with which diet?
Answer: Low-fat, low-fiber soft diet
A low-fat, low-fiber soft diet minimizes pancreatic stimulation during the recovery phase of acute pancreatitis.
