Question 1: Celiac disease requires strict lifelong adherence to which dietary intervention?
- Gluten-free diet (eliminating wheat, barley, and rye) (Correct answer)
- Lactose-free diet
- Low-FODMAP diet
- Elimination of all grains
Correct answer: Gluten-free diet (eliminating wheat, barley, and rye)
Celiac disease is an autoimmune disorder triggered by gluten; strict avoidance of wheat, barley, rye (and often oats due to cross-contamination) allows intestinal healing and symptom resolution.
Question 2: Which dietary approach is evidence-based for managing irritable bowel syndrome (IBS) symptoms?
- Low-FODMAP diet (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) (Correct answer)
- High-fiber diet only
- BRAT diet (bananas, rice, applesauce, toast)
- Specific Carbohydrate Diet
Correct answer: Low-FODMAP diet (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols)
The low-FODMAP diet reduces fermentable carbohydrates that cause osmotic and fermentative symptoms in IBS, with 50-76% of patients experiencing significant symptom improvement.
Question 3: A patient with gout should be counseled to reduce intake of which substances that increase uric acid production?
- High-purine foods (organ meats, shellfish) and alcohol (especially beer) (Correct answer)
- High-oxalate foods (spinach, nuts)
- Dairy products and calcium supplements
- High-fiber foods and legumes
Correct answer: High-purine foods (organ meats, shellfish) and alcohol (especially beer)
Purines are metabolized to uric acid; organ meats, shellfish, and alcohol (especially beer due to guanosine content) significantly increase serum urate and gout risk.
Question 4: In enteral nutrition, what does the term 'elemental formula' indicate?
- Pre-digested formula with free amino acids, simple sugars, and minimal fat for impaired digestion (Correct answer)
- Standard polymeric formula for patients with normal GI function
- High-protein formula for wound healing
- Blenderized whole-food tube feeding
Correct answer: Pre-digested formula with free amino acids, simple sugars, and minimal fat for impaired digestion
Elemental formulas contain hydrolyzed macronutrients (free amino acids, glucose polymers, MCT oil) requiring minimal digestion, intended for patients with severe malabsorption, short bowel syndrome, or pancreatic insufficiency.
Question 5: Which nutritional strategy is recommended to reduce the risk of neural tube defects during early pregnancy?
- 400-800 mcg of folic acid daily starting before conception and through the first trimester (Correct answer)
- High-dose vitamin A supplementation
- Increased calcium intake starting at conception
- Omega-3 supplementation beginning in the second trimester
Correct answer: 400-800 mcg of folic acid daily starting before conception and through the first trimester
Periconceptional folic acid supplementation (400-800 mcg/day) reduces the risk of neural tube defects (spina bifida, anencephaly) by 50-70% by supporting proper neural tube closure.
Question 6: For osteoporosis prevention and treatment, which two nutrients work synergistically to support bone health?
- Calcium and vitamin D (Correct answer)
- Calcium and vitamin C
- Phosphorus and magnesium
- Vitamin K and iron
Correct answer: Calcium and vitamin D
Calcium provides the structural mineral for bone matrix while vitamin D enhances intestinal calcium absorption; both are essential for maintaining bone mineral density and reducing fracture risk.
