,Q1. A 45-year-old man with a history of type 2 diabetes mellitus and hypertension presents with new-onset
nephropathy. His eGFR is 45 mL/min/1.73 m², and 24-hour urine protein is 1.2 g. He has been following a
standard diabetic diet (45-60% carbohydrates, 15-20% protein, <30% fat). Which modification of his dietary
protein intake is most strongly supported by current evidence to slow the progression of his diabetic
nephropathy?
A. Increase protein intake to 1.5 g/kg/day to compensate for proteinuria.
B. Maintain current protein intake at 0.8-1.0 g/kg/day but emphasize plant-based sources.
C. Reduce protein intake to 0.6 g/kg/day with complete replacement of animal protein with soy protein.
D. Restrict protein intake to 0.3 g/kg/day with essential amino acid supplementation.
Correct Answer: B. Maintain current protein intake at 0.8-1.0 g/kg/day but emphasize plant-based sources.
Rationale: For non-dialysis patients with diabetic nephropathy and an eGFR <60, current guidelines recommend a
protein intake of 0.8-1.0 g/kg/day, with emphasis on plant-based proteins to reduce hyperfiltration and
inflammation. Option A would exacerbate proteinuria and renal workload. Option C is too restrictive and may lead
to malnutrition; severe restriction (0.6 g/kg) is reserved for selected patients under close monitoring. Option D is
only for specific metabolic disorders, not diabetic nephropathy.
Why Wrong:
A - Increasing protein intake to 1.5 g/kg/day would worsen hyperfiltration and accelerate renal decline.
C - Reducing protein to 0.6 g/kg/day is unnecessarily restrictive and risks malnutrition without clear benefit
over moderate restriction.
D - Protein restriction to 0.3 g/kg/day with essential amino acid supplementation is not indicated for diabetic
nephropathy and may cause deficiency.

Q2. A 30-year-old woman with a history of bariatric surgery (Roux-en-Y gastric bypass) 5 years ago presents
with fatigue, paresthesias, and a hemolytic anemia. Laboratory findings show low haptoglobin, elevated
lactate dehydrogenase, and a normal MCV. Which of the following is the most likely nutritional deficiency
underlying her presentation?
A. Iron deficiency
B. Vitamin B12 deficiency
C. Copper deficiency
D. Folate deficiency
Correct Answer: C. Copper deficiency
Rationale: Copper deficiency can present with a hemolytic anemia (low haptoglobin, elevated LDH) and
neurological symptoms (paresthesias) with a normal MCV, mimicking B12 deficiency but without macrocytosis.
Iron deficiency typically causes microcytic anemia. B12 and folate deficiencies cause macrocytic anemia. After
gastric bypass, copper deficiency is underrecognized due to reduced absorption.
Why Wrong:
A - Iron deficiency leads to microcytic anemia, not hemolytic anemia with normal MCV.
B - Vitamin B12 deficiency causes macrocytic anemia, not normal MCV, and typically does not present with
hemolysis.
D - Folate deficiency also causes macrocytic anemia and lacks the neurological symptoms seen here.

Q3. A clinical trial investigates the effect of a high-protein diet (2.0 g/kg/day) on muscle protein synthesis in
healthy older adults. The researchers measure the fractional synthetic rate (FSR) of muscle protein using
isotope tracer techniques. Which of the following mechanisms best explains the observed increase in FSR
after a single high-protein meal?
Page 3
, A. Increased phosphorylation of AMPK, leading to enhanced autophagy and amino acid recycling.
B. Activation of the mTORC1 signaling pathway by leucine, promoting translation initiation and elongation.
C. Upregulation of ubiquitin-proteasome pathway, increasing protein turnover and synthesis.
D. Stimulation of myostatin expression, which enhances satellite cell proliferation and fusion.
Correct Answer: B. Activation of the mTORC1 signaling pathway by leucine, promoting translation initiation and
elongation.
Rationale: Leucine, a branched-chain amino acid abundant in high-protein meals, directly activates mTORC1, which
phosphorylates downstream targets like S6K1 and 4E-BP1, increasing mRNA translation and muscle protein synthesis. AMPK
activation promotes catabolism, not anabolism. The ubiquitin-proteasome pathway is primarily involved in protein
degradation. Myostatin inhibits muscle growth.
Why Wrong:
A - AMPK activation suppresses mTORC1 and promotes catabolic processes, not protein synthesis.
C - The ubiquitin-proteasome pathway degrades proteins, reducing net synthesis.
D - Myostatin is a negative regulator of muscle mass; its stimulation would inhibit growth.

Q4. A 55-year-old man with metabolic syndrome is advised to adopt a dietary pattern to reduce
cardiovascular risk. He has a strong family history of premature coronary artery disease. Which of the
following dietary interventions is most likely to reduce his serum triglycerides and improve his LDL particle
profile?
A. A low-fat, high-carbohydrate diet (10% fat, 75% carbohydrate)
B. A Mediterranean diet rich in monounsaturated fats and omega-3 fatty acids
C. A high-saturated fat, low-carbohydrate ketogenic diet
D. A vegan diet with emphasis on whole grains and legumes
Correct Answer: B. A Mediterranean diet rich in monounsaturated fats and omega-3 fatty acids
Rationale: The Mediterranean diet, with its high content of monounsaturated fats (olive oil) and omega-3s (fish),
reduces triglycerides, increases HDL, and improves LDL particle size (less atherogenic). A low-fat,
high-carbohydrate diet often raises triglycerides and lowers HDL. A ketogenic diet may lower triglycerides but
raises LDL in many individuals. A vegan diet can be beneficial but is less effective for triglyceride reduction
compared to Mediterranean diet.
Why Wrong:
A - Low-fat, high-carbohydrate diets tend to increase triglycerides and decrease HDL cholesterol.
C - Ketogenic diets often raise LDL cholesterol due to high saturated fat content.
D - A vegan diet may not provide enough omega-3s to significantly lower triglycerides.

Mediterranean diet. N Engl J Med. 2013;368(14):1279-1290.
Q5. A 40-year-old woman with a history of recurrent calcium oxalate kidney stones is evaluated. She has a
high urinary oxalate level. Which of the following dietary recommendations is most appropriate to reduce
her oxalate excretion?
A. Increase intake of high-oxalate foods like spinach and almonds to promote oxalate binding in the gut.
B. Ensure adequate calcium intake (>1000 mg/day) from dietary sources to bind oxalate in the intestine.
C. Supplement with vitamin C (1000 mg/day) to reduce oxalate production.
D. Restrict all dietary calcium to less than 400 mg/day to reduce urinary calcium excretion.
Correct Answer: B. Ensure adequate calcium intake (>1000 mg/day) from dietary sources to bind oxalate in
the intestine.
Rationale: Dietary calcium binds oxalate in the gut, reducing its absorption and subsequent urinary excretion. This
lowers the risk of calcium oxalate stones. High-oxalate foods should be limited, not increased. Vitamin C is
