100 Multiple-Choice Questions | 7 Sections | Cognitive Levels: 20% Recall, 50% Application, 30% Analysis
Section 1: Principles of Nutrition & Macronutrients
Topics: carbohydrates, proteins, lipids, energy balance, BMR/REE/TEE, AMDR, MyPlate, nutrient density, glycemic
index/load, digestion & metabolism.
Q1: A 24-year-old female client asks the nurse why complex carbohydrates are recommended over simple
sugars. Which response by the nurse best reflects the underlying metabolic rationale?
A. Complex carbohydrates are absorbed more slowly, producing a gradual rise in blood glucose and
sustained energy release. *[CORRECT]*
(612.0, 792.0). Complex carbohydrates contain fewer calories per gram than simple sugars.
(612.0, 792.0). Complex carbohydrates bypass hepatic metabolism and are converted directly to ATP.
(612.0, 792.0). Complex carbohydrates do not require insulin for cellular uptake unlike simple sugars.
Correct Answer: A
Rationale: Complex carbohydrates (starches, fiber-rich foods) consist of long glucose chains that require enzymatic
hydrolysis, slowing digestion and producing a gradual glycemic response (ATI Nutrition: Macronutrient Metabolism).
Simple sugars are rapidly absorbed, causing sharp glucose spikes. Carbohydrates yield 4 kcal/g regardless of
complexity, refuting option B. Option C is incorrect because all carbohydrates undergo hepatic processing. Option D is
incorrect because insulin is required for glucose uptake in most cells for both simple and complex carbohydrates.
Q2: A nurse is teaching a client about complementary proteins. Which menu combination demonstrates the
principle of complementary protein pairing?
(612.0, 792.0). Grilled chicken breast with steamed broccoli
B. Brown rice served with black beans and a side of corn *[CORRECT]*
(612.0, 792.0). Greek yogurt topped with sliced almonds
(612.0, 792.0). Whole-wheat toast with butter and jam
Correct Answer: B
Rationale: Complementary proteins combine two or more incomplete plant proteins that, when eaten together (or
within the same day), supply all nine essential amino acids (ATI Nutrition: Protein Quality). Rice (low in lysine,
adequate methionine) + beans (adequate lysine, low in methionine) form a complete protein. Chicken and yogurt are
already complete animal proteins, so pairing them is not complementary. Butter and jam provide minimal protein.
,Q3: A client consuming 2,200 kcal/day wants to follow the Acceptable Macronutrient Distribution Range
(AMDR). According to AMDR guidelines, what is the recommended range for fat intake as a percentage of
total calories?
(612.0, 792.0). 10-35% of total calories
B. 20-35% of total calories *[CORRECT]*
(612.0, 792.0). 45-65% of total calories
(612.0, 792.0). 5-20% of total calories
Correct Answer: B
Rationale: The AMDR for fat is 20-35% of total calories for adults (ATI Nutrition: Macronutrient Distribution Ranges).
Option A (10-35%) is the AMDR for protein. Option C (45-65%) is the AMDR for carbohydrates. Option D does not
correspond to any macronutrient AMDR. Following AMDR ensures adequate intake while reducing chronic disease
risk.
Q4: A nurse is calculating a client's total energy expenditure (TEE). The client is a 30-year-old male
construction worker. Which component contributes the LARGEST portion of TEE in this individual?
(612.0, 792.0). Basal Metabolic Rate (BMR)
(612.0, 792.0). Thermic Effect of Food (TEF)
C. Physical Activity Energy Expenditure (PAEE) *[CORRECT]*
(612.0, 792.0). Adaptive Thermogenesis
Correct Answer: C
Rationale: For very active individuals (construction workers, athletes), Physical Activity Energy Expenditure can
surpass BMR and become the largest component of TEE (ATI Nutrition: Energy Balance). For sedentary individuals,
BMR (60-75%) dominates. TEF is consistently the smallest (10%). Adaptive thermogenesis is variable but generally
minor. Recognizing the dominant component guides individualized calorie planning.
Q5: A client with newly diagnosed prediabetes asks about the glycemic index (GI). Which food has the
LOWEST glycemic index?
(612.0, 792.0). White rice
(612.0, 792.0). Baked potato
C. Lentils *[CORRECT]*
(612.0, 792.0). Watermelon
Correct Answer: C
Rationale: Lentils have a low GI (around 32) because their high soluble fiber and protein content slow digestion and
glucose absorption (ATI Nutrition: Glycemic Index/Load). White rice, baked potato, and watermelon all have high GI
values (above 70). Low-GI foods help stabilize blood glucose and are emphasized in diabetic nutrition therapy.
,Q6: A nurse is reviewing a food label that lists 'Partially hydrogenated vegetable oil' as the third ingredient.
What is the most important client teaching regarding this ingredient?
(612.0, 792.0). It is a heart-healthy source of omega-3 fatty acids.
B. It contains trans fatty acids, which raise LDL cholesterol and lower HDL cholesterol. *[CORRECT]*
(612.0, 792.0). It is a saturated fat that should be limited to less than 10% of total calories.
(612.0, 792.0). It is a polyunsaturated fat with neutral effects on lipid profile.
Correct Answer: B
Rationale: Partially hydrogenated oils are the primary dietary source of industrial trans fats, which raise LDL and
lower HDL, increasing cardiovascular risk (ATI Nutrition: Lipids; NCLEX-RN Nutrition Standards). The FDA removed
trans fats from the GRAS list in 2018. Omega-3 sources include fatty fish and flaxseed. Saturated fats (option C) include
butter and coconut oil. Trans fats have the most adverse lipid profile of all fats.
Q7: An adult client following a 2,000-kcal diet asks how much dietary fiber is recommended daily. According
to the Dietary Guidelines for Americans, what is the adequate intake (AI) for fiber?
(612.0, 792.0). 10-15 grams per day
B. 14 grams per 1,000 calories (approximately 28 grams/day on a 2,000-kcal diet) *[CORRECT]*
(612.0, 792.0). 35-40 grams per day regardless of caloric intake
(612.0, 792.0). 5 grams per 1,000 calories
Correct Answer: B
Rationale: The Dietary Guidelines for Americans recommend 14 grams of fiber per 1,000 calories consumed, which
equates to ~28 g/day for a 2,000-kcal diet (ATI Nutrition: Fiber). Adequate fiber reduces cardiovascular disease, type 2
diabetes, and constipation. Higher intakes (35-40 g) may be appropriate for some adults but are not the standard AI.
Most Americans consume only ~15 g/day, well below recommendations.
Q8: A nurse is counseling a client on the MyPlate food guidance system. Which statement by the client
indicates a correct understanding of MyPlate recommendations?
(612.0, 792.0). "I should fill half my plate with lean protein foods."
B. "I should make half my plate fruits and vegetables, with grains and protein each filling about a quarter
of the plate." *[CORRECT]*
(612.0, 792.0). "Dairy should make up one-quarter of my plate at every meal."
(612.0, 792.0). "Fruits and grains should each fill one-quarter of my plate, with vegetables filling half."
Correct Answer: B
Rationale: MyPlate divides the plate as: half fruits and vegetables, one-quarter grains (preferably whole), and
one-quarter protein, with a dairy side serving (ATI Nutrition: Dietary Guidelines). Protein is one-quarter, not half.
Dairy is a side item, not on the plate proper. The correct distribution promotes plant-forward, balanced eating.
, Q9: A client asks the nurse what 'nutrient density' means when selecting foods. Which response is most
accurate?
(612.0, 792.0). Nutrient density refers to the physical weight of a food per serving.
B. Nutrient density describes foods that provide a high ratio of vitamins and minerals relative to their
calorie content. *[CORRECT]*
(612.0, 792.0). Nutrient density refers to foods that contain only fat-soluble vitamins.
(612.0, 792.0). Nutrient density describes the calories per gram of macronutrient in a food.
Correct Answer: B
Rationale: Nutrient-dense foods provide substantial vitamins and minerals per calorie (e.g., leafy greens, legumes, lean
proteins) (ATI Nutrition: Nutrient Density). Empty-calorie foods (soda, candy) provide calories with minimal nutrients.
Choosing nutrient-dense foods supports health while meeting calorie goals. Option D refers to caloric density, a
different concept.
Q10: A client who is sedentary asks how to estimate her Resting Energy Expenditure (REE). The client is a
45-year-old female, 65 kg, 165 cm tall. Using the Mifflin-St Jeor equation, which formula is appropriate?
A. REE = 10(weight kg) + 6.25(height cm) - 5(age) - 161 *[CORRECT]*
(612.0, 792.0). REE = 655.1 + 9.6(weight kg) + 1.85(height cm) - 4.7(age)
(612.0, 792.0). REE = 66.5 + 13.8(weight kg) + 5(height cm) - 6.8(age)
(612.0, 792.0). REE = weight (kg) × 30 kcal/kg
Correct Answer: A
Rationale: The Mifflin-St Jeor equation for females is: REE = 10(weight kg) + 6.25(height cm) - 5(age) - 161 (ATI
Nutrition: Energy Expenditure). Option B is the Harris-Benedict equation for women. Option C is Harris-Benedict for
men. Option D is a quick clinical estimate (25-30 kcal/kg), not a predictive equation. Mifflin-St Jeor is currently
considered the most accurate predictive equation.
Q11: A nurse is teaching about lipid digestion. Where does the majority of fat absorption occur, and in what
form are fats transported into the lymphatic system?
(612.0, 792.0). Stomach as free fatty acids entering the portal vein
B. Small intestine as chylomicrons entering the lymphatic lacteals *[CORRECT]*
(612.0, 792.0). Large intestine as bile salts entering the bloodstream
(612.0, 792.0). Liver as very-low-density lipoproteins entering the bile
Correct Answer: B
Rationale: Most fat digestion and absorption occur in the small intestine, where pancreatic lipase breaks triglycerides
into monoglycerides and free fatty acids. These are reassembled into triglycerides, packaged with cholesterol and
apolipoproteins into chylomicrons, and absorbed into lymphatic lacteals (ATI Nutrition: Lipid Digestion/Absorption).
Chylomicrons enter circulation via the thoracic duct. Short-chain fatty acids can enter the portal vein directly, but most
fats use the lymphatic route.
