Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants. It indicates possible hip dislocation or instability, making it a key clinical manifestation to assess for DDH. Dislocated patella (Choice A) is not typically associated with DDH. Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.

This emotional connection can lead Farah to choose foods that provide comfort or familiarity rather than being based on regional cuisines (choice A), general preferences (choice B), or positive associations (choice D).

Correct Answer: C

Rationale: To calculate the percentage of total energy contributed by fat, first determine the energy from fat by multiplying the fat amount (30g) by the energy density of fat (9 kcal/g), which equals 270 kcal. Then, divide the energy from fat (270 kcal) by the total energy intake (1400 kcal) and multiply by 100 to find the percentage: (270 kcal / 1400 kcal) * 100 = 19.29% ≈ 19.00%. Therefore, fat contributes approximately 19% of the total energy in the diet. Choice A (8.50%) is too low, while choices B (15.00%) and D (25.50%) are incorrect calculations based on the given information.

Correct Answer: B

Rationale: Ketoacidosis is a prevalent complication of uncontrolled type 1 diabetes in children. It is a serious condition characterized by high levels of ketones in the blood, leading to acidosis. Prompt medical attention is necessary to manage this potentially life-threatening condition. Choice A, hyperactivity, is not a typical complication of uncontrolled type 1 diabetes. Choice C, hypertension, is not a direct complication of type 1 diabetes in children. Choice D, hypoglycemia, is more commonly associated with low blood sugar levels, which can occur due to excessive insulin administration or inadequate food intake in diabetic individuals, rather than uncontrolled type 1 diabetes.

Rationale: Corrected Question: Vitamin C is considered a micronutrient because it is required in small amounts for proper body functioning and is essential for health.

Vitamin C, being a micronutrient, plays a crucial role in various bodily functions even though it is needed in smaller quantities compared to macronutrients. Therefore, the correct answer is C. Choice A (Protein), Choice B (Carbohydrate), and Choice D (Fat) are incorrect as they are macronutrients required in larger amounts for energy and other body functions.
