,Section A - Nutrition Assessment AND Diagnosis
Q1.
In a patient with chronic kidney disease (CKD) not yet on dialysis, which dietary
modification is most critical to delay disease progression?
A. Increase potassium intake to counteract B. Restrict dietary protein to 0.6-0.8
metabolic acidosis. g/kg/day with close monitoring.
C. Eliminate all phosphorus-containing D. Encourage high-protein intake to prevent
foods regardless of serum levels. muscle wasting.
Correct: B - Restrict dietary protein to 0.6-0.8 g/kg/day with close monitoring.
Rationale:In non-dialysis CKD, moderate protein restriction (0.6-0.8 g/kg/day) is
recommended to reduce uremic toxins and slow progression. High potassium is risky due to
impaired excretion; total phosphorus restriction is not absolute, and high protein accelerates
decline.
Q2.
A patient with type 2 diabetes on metformin and insulin reports frequent hypoglycemia.
Which carbohydrate modification is most appropriate to stabilize glycemic control?
A. Eliminate all carbohydrates to prevent B. Focus on low-glycemic index
glucose spikes. carbohydrates distributed evenly across
meals.
C. Consume most carbohydrates at dinner D. Use only simple sugars for rapid glucose
to match insulin peaks. correction.
Correct: B - Focus on low-glycemic index carbohydrates distributed evenly across meals.
Rationale:Low-GI carbohydrates with consistent distribution help match insulin action and
reduce hypoglycemia. Eliminating carbs is unsafe; simple sugars worsen fluctuations; timing
carbs at dinner is not evidence-based.
Q3.
Which micronutrient deficiency is most likely to present with glossitis, angular cheilitis,
and seborrheic dermatitis in a patient with poor dietary intake?
A. Vitamin C B. Vitamin B2 (riboflavin)
C. Vitamin A D. Zinc
Correct: B - Vitamin B2 (riboflavin)
Page 3
, Section A - Nutrition Assessment AND Diagnosis
Rationale: Riboflavin deficiency classically causes glossitis, angular cheilitis, and seborrheic
dermatitis. Vitamin C deficiency causes scurvy; vitamin A affects vision and skin; zinc
deficiency also causes dermatitis but is less specific.
Q4.
In a critically ill patient receiving enteral nutrition, which parameter is most indicative of
adequate protein delivery?
A. Serum albumin level. B. Nitrogen balance study.
C. Daily weight measurement. D. Prealbumin trend over 1 week.
Correct: B - Nitrogen balance study.
Rationale:Nitrogen balance directly reflects protein intake versus losses, making it the gold
standard for assessing protein adequacy. Albumin and prealbumin are affected by
inflammation and fluid status; weight changes reflect hydration and overall energy balance.
Q5.
Which nutrition intervention is first-line for a patient with newly diagnosed celiac disease?
A. Low-FODMAP diet to reduce B. Gluten-free diet with avoidance of all
gastrointestinal symptoms. wheat, barley, and rye.
C. High-fiber diet to improve bowel D. Lactose-free diet to manage secondary
regularity. lactase deficiency.
Correct: B - Gluten-free diet with avoidance of all wheat, barley, and rye.
Rationale:Strict gluten-free diet is the only effective treatment for celiac disease, allowing
intestinal healing. Low-FODMAP may help IBS symptoms but does not treat celiac; high fiber
may worsen symptoms; lactose-free is only temporary if lactase deficiency exists.
Q6.
A patient on parenteral nutrition develops refeeding syndrome. Which electrolyte
abnormality is most characteristic?
A. Hyperkalemia B. Hypophosphatemia
C. Hypernatremia D. Hypocalcemia
Correct: B - Hypophosphatemia
Rationale:Refeeding syndrome is driven by insulin surge causing intracellular shift of
phosphate, leading to hypophosphatemia. Hypokalemia and hypomagnesemia also occur, but
hypophosphatemia is the hallmark. Hyperkalemia and hypernatremia are not typical.
