BIOD 121 FINAL EXAM REVIEW QUESTIONS
WITH ANSWERS AND EXPLANATIONS
Question 1.
Which comparison best distinguishes Older adult nutrition from a related nutrition
concept?
A. Vitamin E functions primarily as an antioxidant, unlike vitamin K's clotting role
B. Soluble fiber differs from insoluble fiber by forming viscous gels in water
C. Essential amino acids must come from food; nonessential amino acids can be
synthesized
D. Older adults may need fewer calories but not fewer essential nutrients
Correct Answer: D. Older adults may need fewer calories but not fewer essential
nutrients
Explanation: This choice fits the clinical picture because Older adult nutrition is best
understood in relation to nutrition adapted to age-related changes in appetite, body
composition, and absorption and prioritizes protein, hydration, calcium, vitamin d, b12,
and nutrient density. In this context, Older adults may need fewer calories but not fewer
essential nutrients directly addresses the concept being tested. The other options are
more closely associated with other nutrients, diet patterns, or assessment principles with
different functions and therefore do not fit as well. Recognizing this distinction supports
accurate nutrition assessment, counseling, and interpretation of exam scenarios in exam
questions and clinical decision-making.
Question 2.
A client asks how to apply the concept of Lactose intolerance in everyday nutrition. Which
recommendation is most appropriate?
A. Strict avoidance and emergency planning are central for true allergy
B. Increase intake gradually and drink adequate fluid
C. Use lactose-reduced foods or smaller portions as tolerated
D. Follow a strict lifelong gluten-free diet after appropriate diagnosis
Correct Answer: C. Use lactose-reduced foods or smaller portions as tolerated
Explanation: The key point is that Lactose intolerance is best understood in relation to
reduced lactase activity causing malabsorption of lactose and causes gas, bloating, and
diarrhea after sufficient lactose intake. In this context, Use lactose-reduced foods or
smaller portions as tolerated directly addresses the concept being tested. The other
options are more closely associated with other nutrients, diet patterns, or assessment
principles with different functions and therefore do not fit as well. Recognizing this
distinction supports accurate nutrition assessment, counseling, and interpretation of exam
scenarios in exam questions and clinical decision-making.
,Question 3.
Which risk or clinical problem is most closely associated with an imbalance or misuse of
Pantothenic acid B5?
A. Extreme distributions may compromise nutrient adequacy or chronic disease risk
B. Deficiency is rare because the vitamin is widespread in foods
C. Excess refined carbohydrate can displace nutrient-dense foods and worsen glycemic
control
D. Inadequate folate raises neural tube defect risk; inadequate iron raises anemia risk
Correct Answer: B. Deficiency is rare because the vitamin is widespread in foods
Explanation: This choice fits the clinical picture because Pantothenic acid B5 is best
understood in relation to a water-soluble vitamin component of coenzyme a and supports
fatty-acid metabolism and acetyl-group transfer. In this context, Deficiency is rare because
the vitamin is widespread in foods directly addresses the concept being tested. The other
options are more closely associated with other nutrients, diet patterns, or assessment
principles with different functions and therefore do not fit as well. Recognizing this
distinction supports accurate nutrition assessment, counseling, and interpretation of exam
scenarios in exam questions and clinical decision-making.
Question 4.
A client asks how to apply the concept of Hypertension nutrition in everyday nutrition.
Which recommendation is most appropriate?
A. Reduce sodium and increase nutrient-dense potassium-rich foods when kidney function
permits
B. Emphasize unsaturated fats while limiting saturated and trans fats
C. Useful when randomization is impractical or unethical
D. Pay attention to iron for menstruating adolescents and calcium for peak bone mass
Correct Answer: A. Reduce sodium and increase nutrient-dense potassium-rich
foods when kidney function permits
Explanation: This choice fits the clinical picture because Hypertension nutrition is best
understood in relation to dietary strategies that support lower blood pressure and
emphasizes lower sodium, adequate potassium, and overall diet quality. In this context,
Reduce sodium and increase nutrient-dense potassium-rich foods when kidney function
permits directly addresses the concept being tested. The other options are more closely
associated with other nutrients, diet patterns, or assessment principles with different
functions and therefore do not fit as well. Recognizing this distinction supports accurate
nutrition assessment, counseling, and interpretation of exam scenarios in exam questions
and clinical decision-making.
,Question 5.
Which risk or clinical problem is most closely associated with an imbalance or misuse of
Added sugars?
A. Oxidative damage can occur when oils are repeatedly overheated
B. Cross-contamination and temperature abuse increase infection risk
C. Excess during tooth development can cause fluorosis
D. High intake can displace nutritious foods and raise energy intake
Correct Answer: D. High intake can displace nutritious foods and raise energy
intake
Explanation: This option is correct because Added sugars is best understood in relation to
sugars added during processing or preparation rather than naturally occurring in intact
foods and provide energy with few intrinsic micronutrients. In this context, High intake can
displace nutritious foods and raise energy intake directly addresses the concept being
tested. The other options are more closely associated with other nutrients, diet patterns,
or assessment principles with different functions and therefore do not fit as well.
Recognizing this distinction supports accurate nutrition assessment, counseling, and
interpretation of exam scenarios in exam questions and clinical decision-making.
Question 6.
A client asks how to apply the concept of Leptin in everyday nutrition. Which
recommendation is most appropriate?
A. Limit added sugars within an overall nutrient-dense pattern
B. Obesity often involves leptin resistance rather than simple leptin deficiency
C. Use to replace saturated fat and meet essential fatty-acid needs
D. Long-term high-dose zinc can cause copper deficiency
Correct Answer: B. Obesity often involves leptin resistance rather than simple
leptin deficiency
Explanation: This choice fits the clinical picture because Leptin is best understood in
relation to an adipose-derived hormone that signals stored energy to the brain and helps
suppress appetite and regulate energy expenditure. In this context, Obesity often involves
leptin resistance rather than simple leptin deficiency directly addresses the concept being
tested. The other options are more closely associated with other nutrients, diet patterns,
or assessment principles with different functions and therefore do not fit as well.
Recognizing this distinction supports accurate nutrition assessment, counseling, and
interpretation of exam scenarios in exam questions and clinical decision-making.
, Question 7.
Which statement best defines Mediterranean-style pattern?
A. A dietary pattern rich in plant foods, olive oil, nuts, legumes, whole grains, and fish
B. A recommended intake used when evidence is insufficient to establish an EAR and RDA
C. An adipose-derived hormone that signals stored energy to the brain
D. A range of macronutrient intake associated with adequate nutrients and reduced
chronic disease risk
Correct Answer: A. A dietary pattern rich in plant foods, olive oil, nuts, legumes,
whole grains, and fish
Explanation: The key point is that Mediterranean-style pattern is best understood in
relation to a dietary pattern rich in plant foods, olive oil, nuts, legumes, whole grains, and
fish and associated with cardiovascular benefit and high nutrient density. In this context, A
dietary pattern rich in plant foods, olive oil, nuts, legumes, whole grains, and fish directly
addresses the concept being tested. The other options are more closely associated with
other nutrients, diet patterns, or assessment principles with different functions and
therefore do not fit as well. Recognizing this distinction supports accurate nutrition
assessment, counseling, and interpretation of exam scenarios in exam questions and
clinical decision-making.
Question 8.
A client asks how to apply the concept of Randomized controlled trial in everyday nutrition.
Which recommendation is most appropriate?
A. Meet calcium and vitamin D needs throughout life, especially during bone-building years
B. Long-term high-dose zinc can cause copper deficiency
C. Evaluate adherence, blinding, attrition, and clinical relevance
D. Match intake to duration and intensity of activity
Correct Answer: C. Evaluate adherence, blinding, attrition, and clinical relevance
Explanation: The most relevant principle is that Randomized controlled trial is best
understood in relation to an experimental design that randomly assigns participants to
interventions and best supports causal inference when well designed and ethical. In this
context, Evaluate adherence, blinding, attrition, and clinical relevance directly addresses
the concept being tested. The other options are more closely associated with other
nutrients, diet patterns, or assessment principles with different functions and therefore do
not fit as well. Recognizing this distinction supports accurate nutrition assessment,
counseling, and interpretation of exam scenarios in exam questions and clinical
decision-making.
