Foundations of Nutrition & How the Body Uses Nutrients
Q1: A nursing student is reviewing the caloric values of macronutrients. Which of the
following contains the highest number of kilocalories per gram?
A. Protein
B. Carbohydrates
C. Fats [CORRECT]
D. Water
Correct Answer: C
Rationale: The best answer is C because fats provide 9 kcal per gram, whereas
proteins and carbohydrates only provide 4 kcal per gram. Water provides zero calories,
making fat the most energy-dense macronutrient.
Q2: A nurse is teaching a client about fat-soluble vitamins. Which of the following
vitamins should the nurse instruct the client to consume with a dietary fat source to
ensure adequate absorption?
A. Vitamin C
B. Vitamin B12
C. Vitamin D [CORRECT]
D. Thiamine
Correct Answer: C
Rationale: This choice is correct because ATI teaches that vitamins A, D, E, and K are
fat-soluble, meaning they require the presence of dietary fat for proper absorption in the
small intestine. The B-complex vitamins and vitamin C are water-soluble and do not
need fat to be absorbed.
Q3: A client presents with bleeding gums, easy bruising, and poor wound healing. The
nurse recognizes that these clinical manifestations are most likely associated with a
deficiency of which vitamin?
A. Vitamin K
B. Vitamin C [CORRECT]
C. Vitamin A
,D. Vitamin E
Correct Answer: B
Rationale: That aligns with the standard nutritional management of vitamin C deficiency,
as this vitamin is essential for collagen synthesis and capillary integrity. While vitamin K
helps with blood clotting, the gum bleeding and poor wound healing specifically point to
a lack of ascorbic acid.
Q4: A nurse is conducting a nutrition class on major minerals. Which of the following
foods is the richest dietary source of calcium?
A. Orange juice
B. Broccoli
C. Yogurt [CORRECT]
D. Lean beef
Correct Answer: C
Rationale: The best answer is C because dairy products like yogurt are considered the
most concentrated and bioavailable sources of dietary calcium. While broccoli and
fortified orange juice do contain some calcium, you would have to consume very large
portions to match the amount naturally found in a single serving of yogurt.
Q5: A client asks the nurse where the majority of carbohydrate digestion and absorption
takes place. Which of the following responses by the nurse is accurate?
A. The mouth
B. The stomach
C. The duodenum and jejunum [CORRECT]
D. The large intestine
Correct Answer: C
Rationale: This matches what we know about nutrient absorption in the GI tract, as most
enzymatic breakdown of carbohydrates finishes in the small intestine, specifically the
duodenum and jejunum, where the villi absorb the simple sugars directly into the
bloodstream.
Q6: A nurse is calculating the basal metabolic rate (BMR) needs for a client who is
sedentary and needs to maintain their current weight. If the client's BMR is 1,500 kcal,
approximately how many total daily calories does the client need?
A. 1,500 kcal
B. 1,800 kcal [CORRECT]
C. 2,100 kcal
D. 2,400 kcal
Correct Answer: B
Rationale: The best answer is B because for a sedentary individual, the total daily
energy expenditure is typically the BMR multiplied by an activity factor of about 1.2.
, Multiplying 1,500 by 1.2 gives 1,800 kcal, which safely maintains their current weight
without adding extra energy for physical activity.
Q7: A nurse is reviewing a client's 24-hour dietary recall: "I had 2 scrambled eggs with
buttered toast for breakfast, a cheeseburger and fries for lunch, and grilled chicken with
a baked potato and butter for dinner." Based on ATI guidelines for heart-healthy eating,
which nutrient is this client most likely consuming in excess of recommended limits?
A. Complex carbohydrates
B. Saturated fat [CORRECT]
C. Vitamin A
D. Dietary fiber
Correct Answer: B
Rationale: This choice is correct because the foods listed—butter, eggs, cheese, fried
potatoes, and beef—are all heavy in saturated fat, which should be limited to less than
10% of total daily calories to prevent cardiovascular disease. There is very little dietary
fiber or complex carbohydrate in this recall, meaning the client is actually deficient in
those, not exceeding them.
Q8: A nurse is explaining protein digestion to a client with pancreatic insufficiency.
Which of the following enzymes, produced by the pancreas, is primarily responsible for
breaking down proteins into amino acids?
A. Amylase
B. Lipase
C. Trypsin [CORRECT]
D. Lactase
Correct Answer: C
Rationale: The best answer is C because trypsin is the specific pancreatic enzyme that
breaks down intact proteins into smaller peptides and amino acids for absorption.
Amylase handles carbohydrates, lipase handles fats, and lactase is an intestinal
enzyme for milk sugar.
Q9: A nurse is educating a community group on preventing neural tube defects. Which
of the following foods should the nurse recommend as the best natural source of folate?
A. Orange juice [CORRECT]
B. Whole wheat bread
C. Lean pork chop
D. Cheddar cheese
Correct Answer: A
Rationale: This matches what we know about micronutrient sources, as citrus fruits and
dark leafy greens are naturally very high in folate. While whole grains are often fortified
