Foundations of Nutrition & Metabolism (Questions 1–17)
Q1: A nursing student asks the instructor to explain the primary function of carbohydrates in the body.
The instructor's best response is:
A. Carbohydrates are primarily used for building muscle tissue.
B. Carbohydrates are the body's preferred source of energy, providing 4 calories per gram. [CORRECT]
C. Carbohydrates are stored mainly in the liver as protein.
D. Carbohydrates are only needed during periods of intense exercise.
Correct Answer: B
Rationale: This choice is correct because carbohydrates break down into glucose, which fuels everything
from brain function to muscle contraction, and they provide 4 calories per gram—this is why they're the
foundation of a balanced diet.
Q2: A patient asks the nurse why dietary fiber is important. The nurse's best response is:
A. Fiber is digested and absorbed to provide energy.
B. Fiber promotes bowel regularity, helps control blood sugar, and supports heart health by lowering
cholesterol. [CORRECT]
C. Fiber is only necessary for patients with diabetes.
D. Fiber provides essential amino acids for muscle repair.
Correct Answer: B
,Rationale: Fiber isn't digested, but it bulks up stool, slows sugar absorption, and binds cholesterol in the
gut—soluble fiber like oats and beans is especially good for heart health, while insoluble fiber from
whole grains keeps things moving.
Q3: A patient is following a 2,000-calorie diet. According to the Acceptable Macronutrient Distribution
Ranges (AMDR), approximately how many calories should come from carbohydrates?
A. 400–600 calories
B. 900–1,300 calories [CORRECT]
C. 1,400–1,600 calories
D. 1,700–1,900 calories
Correct Answer: B
Rationale: The AMDR for carbohydrates is 45–65% of total calories, so on a 2,000-calorie diet that's 900–
1,300 calories from carbs—this range supports energy needs while leaving room for protein and fat.
Q4: A patient asks the nurse to explain the difference between saturated and unsaturated fats. The
nurse's best response is:
A. Saturated fats are liquid at room temperature and come from plant sources.
B. Saturated fats are solid at room temperature and mainly from animal sources; unsaturated fats are
liquid and mainly from plant sources. [CORRECT]
C. Both types of fat have the same effect on cholesterol levels.
D. Unsaturated fats should be completely avoided in the diet.
Correct Answer: B
Rationale: Saturated fats like butter and lard are solid and raise LDL cholesterol, while unsaturated fats
like olive oil and avocado are liquid and improve lipid profiles—this distinction guides heart-healthy
eating.
Q5: A patient with a history of kidney stones is advised to increase fluid intake. The nurse understands
that the recommended daily fluid intake for most adults is approximately:
A. 4–6 cups
, B. 8–12 cups (64–96 ounces) [CORRECT]
C. 16–20 cups
D. 2–4 cups
Correct Answer: B
Rationale: Most adults need about 8–12 cups of fluid daily from all sources, including food—this keeps
kidneys flushed, supports digestion, and maintains blood volume, though individual needs vary with
activity and climate.
Q6: A patient is prescribed a multivitamin and asks the nurse which vitamin is primarily responsible for
blood clotting. The nurse correctly identifies:
A. Vitamin A
B. Vitamin C
C. Vitamin K [CORRECT]
D. Vitamin E
Correct Answer: C
Rationale: Vitamin K is essential for synthesizing clotting factors II, VII, IX, and X in the liver—without it,
even minor cuts can bleed excessively, which is why newborns get a K shot and why warfarin patients
monitor their intake.
Q7: A patient with fatigue and pallor is found to have a hemoglobin of 9.2 g/dL. The nurse suspects iron
deficiency anemia. Which dietary source of iron is most readily absorbed by the body?
A. Spinach and other leafy greens
B. Fortified cereals
C. Red meat and organ meats (heme iron) [CORRECT]
D. Dairy products
Correct Answer: C
Rationale: Heme iron from animal sources is absorbed at 15–35%, while non-heme iron from plants
absorbs at only 2–20%—pairing plant sources with vitamin C helps, but red meat remains the most
bioavailable source.
