Instructions: This 300-item test bank is designed for ATI RN Nutrition Edition 8.0 mastery and NCLEX-RN preparation.
Each item presents a clinical scenario or direct-recall question with four options (A–D) and exactly one best answer. The
verified correct answer is marked [CORRECT] and is followed by a concise rationale grounded in nutritional principles,
therapeutic diet rationale, and NCLEX-RN clinical judgment. Use the chapter tags for targeted remediation.
SECTION 1: Principles of Nutrition and Nutritional Assessment — Questions 1–30
Chapters 1–3 · Macronutrients, Micronutrients, Assessment Methods
Q1: [Ch 1] Which macronutrient provides the body's primary and preferred source of energy, supplying 4 kcal/g?
A. Carbohydrates [CORRECT]
B. Fats
C. Proteins
D. Alcohol
Correct Answer: A
Rationale: Carbohydrates are the body's primary energy source, especially for the brain and red blood cells, providing 4 kcal/g. Fats
supply 9 kcal/g (more energy but not preferred); proteins supply 4 kcal/g but are mainly structural; alcohol is not a nutrient.
Q2: [Ch 1] A nurse is teaching a client about dietary fiber. Which statement by the client indicates correct
understanding?
A. I will increase fiber slowly and drink extra water to prevent constipation. [CORRECT]
B. Fiber provides concentrated calories that boost weight gain.
C. I should eat all my fiber at one meal to maximize absorption.
D. Fiber is broken down into simple sugars in the small intestine.
Correct Answer: A
Rationale: Fiber should be increased gradually with adequate fluid to prevent gas, bloating, and constipation. Fiber is not calorie-dense,
should be distributed across meals, and is largely indigestible — fermentation occurs in the colon, not the small intestine.

Q3: [Ch 1] Which of the following foods provides complete protein containing all nine essential amino acids?
A. Eggs [CORRECT]
B. Black beans
C. White rice
D. Corn
Correct Answer: A
Rationale: Eggs are a complete (high biologic value) protein. Most plant proteins (beans, rice, corn) are incomplete and lack one or more
essential amino acids; complementary combinations (e.g., beans + rice) are needed for plant-based diets.
Q4: [Ch 1] A client on a low-fat diet asks which fat source is healthiest. Which option is best?
A. Unsaturated fats such as olive oil, avocado, and nuts [CORRECT]
B. Butter
C. Coconut oil
D. Partially hydrogenated margarine
Correct Answer: A
Rationale: Unsaturated fats (monounsaturated and polyunsaturated) lower cardiovascular risk. Butter and coconut oil are high in
saturated fat; partially hydrogenated margarine contains trans fats, which raise LDL and lower HDL.
Q5: [Ch 1] How many kilocalories per gram does dietary fat supply?
A. 9 kcal/g [CORRECT]
B. 4 kcal/g
C. 7 kcal/g
D. 0 kcal/g
Correct Answer: A
Rationale: Fat is the most energy-dense macronutrient at 9 kcal/g — more than double carbs/protein (4 kcal/g). Alcohol supplies 7 kcal/g
but is not a nutrient. Fiber is ~2 kcal/g after colonic fermentation.
Q6: [Ch 1] Which type of lipid is most strongly associated with increased risk of cardiovascular disease?
A. Trans fatty acids [CORRECT]
B. Monounsaturated fats
C. Omega-3 fatty acids
D. Polyunsaturated fats
Correct Answer: A
Rationale: Trans fats (partially hydrogenated oils) raise LDL and lower HDL, strongly increasing cardiovascular risk.
Mono-/polyunsaturated fats and omega-3s are cardio-protective.
Q7: [Ch 2] A client asks which vitamin is fat-soluble. The nurse correctly identifies:
A. Vitamin A [CORRECT]
B. Vitamin C
C. Vitamin B1 (thiamine)
D. Folate
Correct Answer: A
Rationale: Fat-soluble vitamins are A, D, E, and K — stored in the liver and adipose, risk of toxicity. Vitamins C and the B-complex
(thiamine, folate) are water-soluble; excess is excreted in urine.

Q8: [Ch 2] Which vitamin, when deficient, causes night blindness and xerophthalmia?
A. Vitamin A [CORRECT]
B. Vitamin B12
C. Vitamin C
D. Vitamin K
Correct Answer: A
Rationale: Vitamin A is essential for rhodopsin synthesis in the retina; deficiency causes night blindness and xerophthalmia (dry eyes),
progressing to corneal ulceration. The other vitamins affect other systems.
Q9: [Ch 2] A client has chronic alcohol use disorder and presents with confusion, ataxia, and nystagmus. Which vitamin
deficiency is most likely?
A. Thiamine (B1) [CORRECT]
B. Riboflavin (B2)
C. Folate (B9)
D. Cobalamin (B12)
Correct Answer: A
Rationale: Wernicke encephalopathy (confusion, ataxia, nystagmus) results from thiamine (B1) deficiency, common in chronic alcohol
use. IV thiamine must precede glucose to avoid precipitating Wernicke.
Q10: [Ch 2] Which finding best supports a diagnosis of scurvy?
A. Bleeding gums and perifollicular petechiae [CORRECT]
B. Rickets and bowing of legs
C. Pellagra with diarrhea and dermatitis
D. Macrocytic anemia
Correct Answer: A
Rationale: Scurvy is vitamin C deficiency; signs include bleeding gums, perifollicular petechiae, poor wound healing, and corkscrew hairs.
Rickets = vitamin D deficiency; pellagra = niacin deficiency; macrocytic anemia = folate/B12 deficiency.
Q11: [Ch 2] Sunlight exposure assists in the synthesis of which vitamin in the skin?
A. Vitamin D [CORRECT]
B. Vitamin A
C. Vitamin B12
D. Vitamin K
Correct Answer: A
Rationale: Ultraviolet B (UVB) light converts 7-dehydrocholesterol in the skin to previtamin D3, then to cholecalciferol (vitamin D3). Liver
and kidneys convert it to its active form, calcitriol.
Q12: [Ch 2] Which vitamin is essential for the synthesis of clotting factors II, VII, IX, and X in the liver?
A. Vitamin K [CORRECT]
B. Vitamin E
C. Vitamin C
D. Vitamin A
Correct Answer: A
Rationale: Vitamin K is the cofactor for gamma-carboxylation of clotting factors II, VII, IX, X, and proteins C and S. Deficiency (e.g., in
newborns or with broad-spectrum antibiotics) causes bleeding; it is reversed with phytonadione.

Q13: [Ch 3] Which laboratory value best reflects long-term protein status in the body?
A. Albumin [CORRECT]
B. Prealbumin
C. Transferrin
D. Hemoglobin
Correct Answer: A
Rationale: Albumin has a half-life of ~20 days and reflects long-term protein status. Prealbumin (half-life ~2 days) reflects
acute/short-term changes; transferrin reflects iron status; hemoglobin reflects red blood cell mass.
Q14: [Ch 3] Which of the following is the BEST indicator of recent (acute) nutritional status?
A. Prealbumin [CORRECT]
B. Albumin
C. Total lymphocyte count
D. Triceps skinfold
Correct Answer: A
Rationale: Prealbumin half-life ~2 days makes it a sensitive marker of acute nutritional changes; it responds quickly to nutritional
support. Albumin reflects chronic status; lymphocyte count is less specific; skinfold measures body fat.
Q15: [Ch 3] Which anthropometric measurement best reflects visceral protein and fat stores in adults?
A. Body mass index (BMI) [CORRECT]
B. Head circumference
C. Stature for age
D. Weight for length
Correct Answer: A
Rationale: BMI relates weight to height and screens for overweight/obesity and undernutrition. Head circumference is for children <2;
stature-for-age and weight-for-length are pediatric growth chart indices.
Q16: [Ch 3] A client's BMI is 27.5. How should the nurse classify this?
A. Overweight [CORRECT]
B. Normal weight
C. Class I obesity
D. Underweight
Correct Answer: A
Rationale: BMI 25.0–29.9 = overweight; 18.5–24.9 = normal; 30.0–34.9 = Class I obesity; <18.5 = underweight. A BMI of 27.5 falls in the
overweight range.
Q17: [Ch 3] Which technique is part of a comprehensive nutritional assessment using the ABCD method?
A. Anthropometric, Biochemical, Clinical, Dietary [CORRECT]
B. Auscultation, Blood pressure, Cardiovascular, Diet
C. Assessment, Behavior, Counseling, Diet
D. Anthropometric, Body fat, Caloric intake, Drug use
Correct Answer: A
Rationale: ABCD stands for Anthropometric, Biochemical, Clinical, and Dietary assessment. This framework ensures comprehensive data
gathering in nutritional screening.
