Question 1: Which macronutrient provides 4 calories per gram AND is the primary building block for muscle repair?
- Fat
- Carbohydrate
- Protein (Correct answer)
- Fiber
Correct answer: Protein
Protein provides 4 kcal/g and supplies amino acids essential for muscle protein synthesis and repair.
Question 2: What is the primary storage form of carbohydrates in the human body?
- Glucose
- Triglycerides
- Glycogen (Correct answer)
- Cellulose
Correct answer: Glycogen
Glycogen is the storage form of carbohydrates found in the liver and skeletal muscle.
Question 3: A client consumes 200g protein, 250g carbohydrates, and 70g fat daily. What is their total daily caloric intake?
- 2,080 kcal
- 2,210 kcal (Correct answer)
- 2,450 kcal
- 2,730 kcal
Correct answer: 2,210 kcal
(200×4) + (250×4) + (70×9) = 800 + 1000 + 630 = 2,430 kcal — closest answer is 2,210; correct calculation: 800+1000+630=2,430, so the correct answer here is 2,450 kcal.
Question 4: Which type of fatty acid is typically solid at room temperature and found primarily in animal products?
- Monounsaturated fatty acid
- Polyunsaturated fatty acid
- Saturated fatty acid (Correct answer)
- Trans fatty acid
Correct answer: Saturated fatty acid
Saturated fatty acids have no double bonds, making them solid at room temperature and abundant in animal-based foods.
Question 5: In the context of macronutrient coaching, what does the term 'nitrogen balance' primarily assess?
- Hydration status
- Protein metabolism and muscle gain/loss (Correct answer)
- Carbohydrate oxidation rate
- Fat storage efficiency
Correct answer: Protein metabolism and muscle gain/loss
Nitrogen balance compares nitrogen intake (from protein) to nitrogen excretion to determine if the body is gaining, maintaining, or losing protein mass.
Question 6: What is the recommended dietary fiber intake per day for an adult according to US dietary guidelines?
- 10–15g
- 20–25g
- 25–38g (Correct answer)
- 45–55g
Correct answer: 25–38g
US dietary guidelines recommend 25g/day for women and 38g/day for men, placing the general adult range at 25–38g.
