Q.12 A patient with chronic obstructive pulmonary disease develops carbon dioxide retention. Which nutrition strategy may help reduce respiratory burden?
Moderate carbohydrate and higher fat intake
Extremely high carbohydrate feeding plan
Exclusive protein supplementation regimen
Severe calorie restriction during illness
Explanation - Higher fat and moderate carbohydrate feeding may reduce carbon dioxide production compared with excessive carbohydrate intake.
Correct answer is: Moderate carbohydrate and higher fat intake
Q.13 Which anthropometric measurement is commonly used to assess central obesity and cardiometabolic risk?
Waist circumference at standard landmarks
Head circumference measured weekly only
Upper arm length from shoulder
Foot length measured without shoes
Explanation - Waist circumference is a validated measure of abdominal adiposity and metabolic risk.
Correct answer is: Waist circumference at standard landmarks
Q.14 Which electrolyte abnormality is frequently observed in patients receiving aggressive loop diuretic therapy?
Hypokalemia due to urinary potassium loss
Hyperphosphatemia from reduced filtration
Hypercalcemia from intestinal absorption
Hypermagnesemia due to supplementation
Explanation - Loop diuretics commonly increase urinary potassium excretion, resulting in hypokalemia.
Correct answer is: Hypokalemia due to urinary potassium loss
Q.15 In nutrition-focused physical examination, temporal muscle wasting primarily suggests loss of which body compartment?
Skeletal muscle mass stores overall
Visceral fat stores exclusively only
Bone mineral content primarily alone
Extracellular fluid volume compartment
Explanation - Temporal wasting is a recognized indicator of skeletal muscle depletion and protein-energy malnutrition.
Correct answer is: Skeletal muscle mass stores overall
Q.16 A patient after bariatric surgery is at particularly high risk of developing which deficiency if supplementation is inadequate?
Vitamin B12 deficiency over time
