Nutrition & Biochemistry MCQs with Answers

Answer: B. Skin fold

Hb level: Hemoglobin levels are useful for diagnosing anemia, which may indicate malnutrition but do not provide a comprehensive assessment of nutritional status.
Skin fold: Skinfold thickness measures subcutaneous fat and provides an assessment of energy reserves in the body. It is an effective method for evaluating malnutrition, especially when combined with
other indicators.
MUAC: Mid-Upper Arm Circumference (MUAC) is a useful tool for malnutrition assessment but is more commonly applied in resource-limited settings or emergencies.
Chest circumference: This is typically used for assessing growth in infants and young children and is not suitable for evaluating malnutrition in adults.

Answer: C. Thiamine

Thiamine: Wernicke's encephalopathy is caused by a deficiency of thiamine (Vitamin B1), often associated with chronic alcoholism or malnutrition. It leads to confusion, ataxia, and ophthalmoplegia.
Riboflavin: Deficiency of riboflavin (Vitamin B2) causes ariboflavinosis, leading to symptoms like sore throat and cracked lips, not Wernicke's encephalopathy.
Vitamin D: Vitamin D deficiency results in bone disorders like rickets and osteomalacia, unrelated to neurological conditions like Wernicke's encephalopathy.
Vitamin A: Vitamin A deficiency causes vision-related issues such as night blindness, not Wernicke's encephalopathy.
