Advanced Practice Questions Q1-Q100 for Nutrition for Healthy Living (6th Edition)
1. A 45-year-old client with a sedentary lifestyle asks about the appropriate application of
the Dietary Reference Intakes (DRIs) when planning meals for personal wellness. Which
component of the DRIs should the nutrition consultant primarily use to evaluate the
adequacy of the client's micronutrient intake? [Domain: Basics of Nutrition and Dietary
Guidelines]
A) Tolerable Upper Intake Level (UL)
B) Recommended Dietary Allowance (RDA)
C) Estimated Average Requirement (EAR)
D) Adequate Intake (AI)
Correct Answer: B
,Rationale: The Recommended Dietary Allowance (RDA) represents the daily dietary intake level
sufficient to meet the nutrient requirements of nearly all healthy individuals in a particular life
stage and gender group, making it the primary standard for individual diet evaluation. The
Tolerable Upper Intake Level (UL) establishes the maximum daily intake unlikely to cause
adverse health effects rather than assessing adequacy. The Estimated Average Requirement
(EAR) covers only half of the population and is used primarily for evaluating group populations
rather than individual meal planning. Adequate Intake (AI) is utilized when insufficient scientific
evidence is available to establish an RDA, making RDA the more precise target for nutrient
adequacy.
2. A public health dietitian is analyzing food label data for a newly formulated whole-grain
cereal. The product provides 6 grams of dietary fiber per serving, and the manufacturer
wants to claim it is a "high-fiber" food. Based on FDA regulations and nutrient density
guidelines, what percentage of the Daily Value (DV) must a serving provide to legally
support this claim? [Domain: Basics of Nutrition and Dietary Guidelines]
A) 10% or more of the DV
B) 15% or more of the DV
C) 20% or more of the DV
D) 50% or more of the DV
Correct Answer: C
Rationale: According to FDA food labeling regulations, a food designated as a "high" source of
a nutrient must provide 20 percent or more of the Daily Value (DV) per reference amount
customarily consumed. A "good source" claim requires between 10 and 19 percent of the DV.
Option A represents the threshold for a good source rather than a high source. Option D exceeds
regulatory definitions and is typically reserved for specialized fortification designations.
3. During a clinical rotation, a dietetic intern evaluates a patient experiencing chronic
malabsorption syndrome due to surgical resection of the terminal ileum. Which specific
nutrient deficiency is this patient at the highest risk of developing over time? [Domain: The
Human Body: Digestion, Absorption, and Metabolism]
A) Vitamin C
B) Vitamin B12
C) Folate
D) Calcium
Correct Answer: B
Rationale: Vitamin B12 absorption requires intrinsic factor secreted by the stomach, but the
actual absorption of the intrinsic factor-B12 complex takes place specifically in the terminal
ileum. Resection or disease of this specific region disrupts this mechanism, leading to deficiency
despite adequate dietary intake. Vitamin C and calcium are absorbed primarily in the upper
small intestine (duodenum and jejunum). Folate is primarily absorbed in the proximal small
intestine, making Vitamin B12 the unique vulnerability of terminal ileum compromise.
4. A patient with severe exocrine pancreatic insufficiency presents with steatorrhea and fat-
soluble vitamin deficiencies. Which enzyme deficiency is directly responsible for the
,impaired digestion of dietary triglycerides in this clinical presentation? [Domain: The
Human Body: Digestion, Absorption, and Metabolism]
A) Lingual lipase
B) Gastric lipase
C) Pancreatic lipase
D) Enteropeptidase
Correct Answer: C
Rationale: Pancreatic lipase is the primary enzyme responsible for hydrolyzing the majority of
dietary triglycerides into monoglycerides and free fatty acids within the small intestine. Exocrine
pancreatic insufficiency drastically reduces pancreatic enzyme output, leading to fat
malabsorption (steatorrhea). Lingual and gastric lipases play minor roles in infant digestion and
initial lipid breakdown but cannot compensate for pancreatic lipase failure. Enteropeptidase
activates trypsinogen, initiating the proteolytic cascade rather than lipid digestion.
5. A clinical nutritionist is educating a patient with dumping syndrome following gastric
bypass surgery. The patient experiences weakness, dizziness, and palpitations 30 minutes
after consuming a high-carbohydrate meal. What is the underlying physiological
mechanism causing these acute symptoms? [Domain: The Human Body: Digestion,
Absorption, and Metabolism]
A) Delayed gastric emptying causing severe hyperglycemia
B) Rapid fluid shift from the intravascular space into the jejunum due to hyperosmolar
chyme
C) Immediate autoimmune reaction to processed sugars
D) Excessive insulin secretion triggered by slow-release fiber digestion
Correct Answer: B
Rationale: In dumping syndrome, undigested hyperosmolar food enters the small intestine too
rapidly, pulling water from the circulating blood vessels into the intestinal lumen via osmosis.
This acute fluid shift reduces blood volume, causing hypotension, tachycardia, weakness, and
dizziness. Delayed gastric emptying describes gastroparesis rather than dumping syndrome. The
symptoms are driven by rapid fluid shifts and subsequent reactive hypoglycemia, not
autoimmune responses or slow-release fiber.
6. A competitive endurance athlete asks about optimizing glycogen replenishment during a
multi-stage cycling event. Which carbohydrate transporter, located on the brush border of
the enterocyte, is responsible for the sodium-independent facilitated diffusion of fructose?
[Domain: The Human Body: Digestion, Absorption, and Metabolism]
A) SGLT1
B) GLUT5
C) GLUT4
D) GLUT2
Correct Answer: B
Rationale: GLUT5 is the specific brush border transporter responsible for the transport of
fructose into the enterocyte via facilitated diffusion independently of sodium. SGLT1 handles
, active co-transport of glucose and galactose with sodium. GLUT4 is insulin-sensitive and found
in skeletal muscle and adipose tissue, not the intestinal brush border. GLUT2 transports
monosaccharides out of the enterocyte into the basolateral blood circulation.
7. A 60-year-old male with chronic renal failure is counselled on minimizing serum
potassium accumulation. The nutritionist explains how dietary carbohydrates and amino
acids stimulate cellular uptake of potassium. Which hormone is primarily responsible for
shifting potassium intracellularly after a mixed meal? [Domain: Carbohydrates, Lipids,
and Proteins: The Energy Nutrients]
A) Glucagon
B) Cortisol
C) Insulin
D) Epinephrine
Correct Answer: C
Rationale: Insulin stimulates the Na+/K+-ATPase pump on cell membranes, driving potassium
ions from the extracellular fluid into intracellular compartments, particularly in skeletal muscle
and liver cells. This homeostatic mechanism prevents dangerous postprandial hyperkalemia.
Glucagon mobilizes energy stores but does not drive cellular potassium uptake. Cortisol and
epinephrine have complex effects on metabolism, but insulin is the primary hormone regulating
acute postprandial electrolyte shifts.
8. An interpretive culinary class is reviewing the glycemic index (GI) of various complex
carbohydrates. Which dietary factor most significantly lowers the glycemic index of a food
item containing starchy carbohydrates? [Domain: Carbohydrates, Lipids, and Proteins:
The Energy Nutrients]
A) High degree of starch gelatinization through prolonged boiling
B) Complete removal of dietary fiber and outer seed coats
C) Presence of viscous soluble fiber and intact cell structures
D) Consumption of the carbohydrate in liquid beverage form
Correct Answer: C
Rationale: Viscous soluble fibers (such as beta-glucan and pectin) slow gastric emptying and
delay enzymatic access to starches, thereby lowering the glycemic index. Intact plant cell walls
also require physical mastication and digestion, blunting the glucose response. Conversely,
starch gelatinization, fiber removal, and liquid processing accelerate digestion and absorption,
significantly raising the glycemic index.
9. A researcher is evaluating the fatty acid profile of a newly marketed plant spread.
Laboratory analysis reveals the presence of trans-fatty acids created through partial
hydrogenation. How do trans-fatty acids negatively impact cardiovascular health at the
molecular level? [Domain: Carbohydrates, Lipids, and Proteins: The Energy Nutrients]
A) They decrease low-density lipoprotein (LDL) cholesterol and increase triglycerides.
B) They increase low-density lipoprotein (LDL) cholesterol and decrease high-density
lipoprotein (HDL) cholesterol.
C) They inhibit the absorption of essential amino acids in the duodenum.
