A nutrient is best described as:

A nutrient is best described as:

• A. A plan for meals
• B. A substance that provides energy and supports growth and metabolism
• C. A type of calorie
• D. A vitamin

Answer: (B)

Nutrients are substances that provide energy and support growth and metabolism. This definition captures what the body uses to fuel activities, build and repair tissues, and regulate bodily processes, covering both macronutrients (like carbohydrates, proteins, and fats) and micronutrients (such as vitamins and minerals). The other options miss this broader concept: a meal plan is a plan for eating, not a substance; a calorie is a unit of energy, not a substance; and a vitamin is a specific type of nutrient, not all nutrients. In care settings, ensuring residents receive a balanced mix of nutrients supports energy, healing, and overall health, which is especially important for older adults.
