, Question 1
A patient with chronic kidney disease (CKD) stage 4 is prescribed a
low-protein diet (0.6 g/kg/day) with ketoacid analogues. Which metabolic
consequence is most likely if the patient's energy intake is inadequate?
A. Increased urea production and azotemia
B. Enhanced protein anabolism and nitrogen balance
C. Endogenous protein catabolism and negative nitrogen balance
D. Reduced risk of protein-energy wasting
Correct Answer: C - Endogenous protein catabolism and negative
nitrogen balance
RATIONALE
Inadequate energy intake forces the body to catabolize endogenous
proteins for glucose, leading to negative nitrogen balance and
worsening uremia. Ketoacid analogues require sufficient energy to be
utilized for protein synthesis. Options A, B, and D are incorrect
because low energy promotes catabolism, not anabolism or reduced
wasting.
Question 2
Which statement best explains why the glycemic index (GI) of a food may not
predict its glycemic load (GL) or postprandial glycemic response in a mixed
meal?
A. GI is measured in isolation and does not account for the carbohydrate
content or interactions with other macronutrients.
B. GL is determined solely by the fiber content of the food.
C. The GI value is standardized to white bread, while GL uses glucose as
the reference.
D. Mixed meals delay gastric emptying, which uniformly lowers GI but
not GL.
Correct Answer: A - GI is measured in isolation and does not
Page 2
,account for the carbohydrate content or interactions with other
macronutrients.
RATIONALE
GI measures the glycemic response to a fixed amount of available
carbohydrate (usually 50 g) in isolation, whereas GL incorporates the
actual carbohydrate amount in a serving. In mixed meals, fat, protein,
and fiber slow gastric emptying and modify insulin response, so GI
alone is insufficient. B is false because GL depends on both GI and
carbohydrate quantity. C is incorrect because GI can use either glucose
or white bread as reference. D is incorrect because delayed gastric
emptying affects both GI and GL variably.
Question 3
A patient with short bowel syndrome undergoes jejunostomy with loss of the
ileocecal valve. Which nutrient deficiency is most directly attributable to loss
of the terminal ileum?
A. Vitamin B12
B. Iron
C. Calcium
D. Thiamine
Correct Answer: A - Vitamin B12
RATIONALE
The terminal ileum is the primary site for vitamin B12 absorption via
intrinsic factor receptors. Resection leads to B12 deficiency. Iron is
absorbed mainly in the duodenum and proximal jejunum; calcium in
the duodenum; thiamine in the jejunum and ileum but with widespread
absorption. Thus, B12 is the most specific deficiency.
Question 4
Which of the following best describes the primary mechanism by which dietary
fiber lowers LDL cholesterol?
Page 3
, A. Binding bile acids in the intestine, increasing their fecal excretion and
upregulating hepatic LDL receptors
B. Inhibiting HMG-CoA reductase directly in the liver
C. Increasing pancreatic lipase activity and fat malabsorption
D. Enhancing intestinal cholesterol absorption
Correct Answer: A - Binding bile acids in the intestine, increasing
their fecal excretion and upregulating hepatic LDL receptors
RATIONALE
Soluble fiber binds bile acids, preventing their reabsorption; the liver
compensates by converting more cholesterol to bile acids and
upregulating LDL receptors, thus lowering plasma LDL. B is the
mechanism of statins. C is incorrect; fiber does not increase lipase
activity. D is opposite; fiber decreases cholesterol absorption.
Question 5
In the context of nutritional genomics, which polymorphism most consistently
modifies the response to dietary saturated fat and risk of coronary artery
disease?
A. APOA2 -265T>C
B. MTHFR C677T
C. FTO rs9939609
D. ACE I/D
Correct Answer: A - APOA2 -265T>C
RATIONALE
The APOA2 -265T>C polymorphism interacts with saturated fat
intake; carriers of the C allele show increased BMI and insulin
resistance only when saturated fat intake is high. MTHFR relates to
folate metabolism, FTO to obesity risk, and ACE to blood pressure.
Thus, APOA2 is the most consistent for saturated fat response.
