Introduction
This comprehensive examination is designed to assess the foundational knowledge
and applied clinical skills essential for competent practice in the field of nutrition
and dietetics. It evaluates a candidate’s understanding of core scientific principles,
including the metabolism of macronutrients and micronutrients, as well as their
application in diverse physiological states. The assessment utilizes multiple-choice
and scenario-based questions to measure critical thinking and the ability to
integrate evidence-based knowledge into real-world decision-making, from
individual patient counseling to public health policy. Success requires not only
theoretical mastery but also the professional acumen to navigate regulatory
frameworks and uphold the highest ethical standards in practice.
,Section One: Questions 1–50
1. Which of the following is the primary role of insulin in carbohydrate
metabolism?
A. Stimulate glycogenolysis in the liver
B. Enhance glucose uptake into muscle and adipose tissue
C. Promote gluconeogenesis in the kidney
D. Increase the breakdown of triglycerides for energy
🟢 Correct Answer: B. Enhance glucose uptake into muscle and adipose tissue
🔴 Explanation: Insulin is an anabolic hormone that facilitates the transport of
glucose from the bloodstream into cells, particularly skeletal muscle and adipose
tissue, by promoting the translocation of GLUT-4 transporters to the cell
membrane. Glycogenolysis and gluconeogenesis are primarily stimulated by
glucagon and cortisol, not insulin.
2. Which of the following is a hallmark of a deficiency in vitamin B12?
A. Night blindness
B. Pernicious anemia
C. Pellagra
D. Hemolytic anemia
🟢 Correct Answer: B. Pernicious anemia
🔴 Explanation: Pernicious anemia is a specific type of macrocytic anemia caused
by an inability to absorb vitamin B12 due to a lack of intrinsic factor. Night
blindness is associated with vitamin A deficiency, pellagra with niacin deficiency,
and hemolytic anemia with vitamin E deficiency.
3. A patient is prescribed warfarin (Coumadin). Which dietary modification is
most critical to ensure the efficacy and safety of this medication?
,A. Reducing consumption of foods high in potassium
B. Increasing intake of green, leafy vegetables
C. Maintaining a consistent intake of vitamin K
D. Avoiding foods with high glycemic index
🟢 Correct Answer: C. Maintaining a consistent intake of vitamin K
🔴 Explanation: Warfarin is an anticoagulant that acts by inhibiting vitamin K-
dependent clotting factors. Sudden, significant changes in dietary vitamin K
intake, which is abundant in green leafy vegetables, can antagonize or potentiate
the drug's effect, requiring dosage adjustments to maintain the international
normalized ratio (INR) within a therapeutic range.
4. Which of the following correctly describes the nitrogen balance in a healthy,
growing child?
A. Negative nitrogen balance
B. Zero nitrogen balance
C. Positive nitrogen balance
D. Unstable nitrogen balance
🟢 Correct Answer: C. Positive nitrogen balance
🔴 Explanation: A positive nitrogen balance occurs when nitrogen intake (from
dietary protein) exceeds nitrogen excretion (e.g., in urine and feces), indicating
net protein synthesis. This is characteristic of growth, tissue repair, and pregnancy.
A negative balance indicates net protein breakdown, while a stable zero balance
represents maintenance in healthy adults.
5. What is the primary function of cholecystokinin (CCK) in digestion?
A. Stimulate the release of hydrochloric acid in the stomach
B. Promote the secretion of pancreatic enzymes and bile release
, C. Initiate the cephalic phase of gastric secretion
D. Inhibit the action of pancreatic lipase
🟢 Correct Answer: B. Promote the secretion of pancreatic enzymes and bile
release
🔴 Explanation: Cholecystokinin (CCK) is a peptide hormone released by I-cells in
the duodenum in response to the presence of fats and proteins. It stimulates the
gallbladder to contract and release bile and the pancreas to secrete digestive
enzymes, thus facilitating digestion and absorption.
6. A dietitian is educating a client with celiac disease. Which of the following
grains is SAFE for the client to consume?
A. Barley
B. Rye
C. Spelt
D. Amaranth
🟢 Correct Answer: D. Amaranth
🔴 Explanation: Celiac disease is an autoimmune disorder triggered by the
ingestion of gluten, a protein found in wheat, barley, and rye. Spelt is an ancient
form of wheat and is therefore unsafe. Amaranth is a gluten-free pseudo-cereal
and is considered safe for individuals with celiac disease.
7. Which of the following is a characteristic of soluble dietary fiber?
A. Increases fecal bulk primarily by holding water
B. Is poorly fermented by colonic bacteria
C. Can help lower serum cholesterol levels
D. Is found in high concentrations in wheat bran
🟢 Correct Answer: C. Can help lower serum cholesterol levels
