This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Macronutrients
Prompt focus: A client asks how many calories are provided per gram by each macronutrient. Which statement correctly describes the energy content of carbohydrates, protein, and fat?
Why the correct answer works
Carbohydrates and protein each provide 4 calories per gram, and fat provides 9 calories per gram
Carbohydrate and protein each yield 4 calories per gram, while fat yields 9 calories per gram.
Why the tempting wrong answer fails
Fat provides 9 calories per gram, not 4, so they are not all equal.
Plain-language takeaway
The energy values of macronutrients are standardized at 4 calories per gram for both carbohydrate and protein, and 9 calories per gram for fat. These values are used to estimate the energy content of foods.
Simple analogy
Think of macronutrients like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
