**Question:** Approximate caloric requirements of an infant at the age of 12 months would be -

A. 600-700 calories/day
B. 700-800 calories/day
C. 800-900 calories/day
D. 900-1000 calories/day

**Correct Answer:** D. 900-1000 calories/day

**Core Concept:** Caloric requirements in infants are influenced by several factors, including age, growth rate, activity level, and overall health status.

**Why the Correct Answer is Right:** Infants at the age of 12 months typically undergo rapid growth and development, especially in the area of height and weight gain. As a result, their caloric requirements are higher than those of older children or adults. On average, infants at 12 months require between 900-1000 calories per day to support their growth and development.

**Why Each Wrong Option is Incorrect:**

A. Infants at 12 months are growing rapidly, so a lower caloric requirement would not be sufficient to meet their nutritional needs.
B. While infants continue to grow, their energy expenditure does not increase proportionally to their caloric needs, making this option too high.
C. Similar to Option A, this range is too low due to the infant's growing needs.
D. This is the correct answer, explaining the reason for choosing it correctly. However, it should be noted that infants are generally more active during meals and feeding times, contributing to increased energy expenditure.

**Clinical Pearl:** Understanding caloric requirements in infants is essential for ensuring proper growth and development. Overfeeding can lead to obesity, while underfeeding may impede growth and result in malnutrition. Adequate caloric intake is crucial for a child's overall health and well-being.

**Why Each Wrong Option is Incorrect:**

A. Inaccurately represents the average caloric requirements of 12-month-olds.
B. Although infants burn more calories during play and activity, the energy expenditure does not increase dramatically at this age, making this option too high.
C. Similar to Option A, this range is too low due to the infant's growing needs.
D. This answer is correct but should be adjusted to consider the increased energy expenditure during feeding and growth spurt periods.

**Why Option D is Right:**

Infants experience increased energy expenditure during meal times and growth spurts. This increased activity contributes to the higher caloric requirements at this age.

**Option D Explanation:**

Caloric requirements of infants depend on factors like weight, height, and activity levels. However, for simplicity, we can consider the average infant's requirements based on their age. Infants at 12 months require approximately 900-1000 calories per day to meet the nutritional needs for growth and development.

**Core Concept:** Proper nutrition in infants plays a crucial role in their growth, development, and overall health. Understanding the caloric requirements at different ages is essential for ensuring optimal growth and
