Q.10 During a nutrition-focused physical examination, bilateral pitting edema may lead to:

Underestimation of nutritional deficiency
Overestimation of actual body weight
Reduction in measured waist circumference
Improved accuracy of BMI calculation
Explanation - Fluid accumulation artificially increases body weight and can mask underlying malnutrition.
Correct answer is: Overestimation of actual body weight

Q.11 Which biochemical assessment is considered the gold standard for evaluating iron stores in the absence of inflammation?

Serum ferritin concentration measurement
Mean corpuscular volume determination
Hemoglobin concentration evaluation test
Transferrin saturation percentage value
Explanation - Serum ferritin closely reflects body iron stores when inflammatory processes are absent.
Correct answer is: Serum ferritin concentration measurement

Q.12 A major advantage of food frequency questionnaires in population studies is:

Direct measurement of metabolic rate
Identification of biochemical deficiencies
Explanation - FFQs are designed to estimate habitual dietary intake over extended periods.
Correct answer is: Assessment of long-term dietary patterns

Q.13 Which parameter is included in the Malnutrition Universal Screening Tool (MUST)?
