Introduction
This comprehensive examination has been developed to assess foundational knowledge, clinical reasoning,
and practical application skills essential for professional nutrition practice. The assessment covers core
competencies including macronutrient and micronutrient metabolism, nutrition assessment
methodologies, medical nutrition therapy across diverse disease states, and ethical considerations in
patient care. Through a combination of theoretical questions and scenario-based items, candidates will
demonstrate their ability to integrate scientific principles with real-world clinical decision-making. Each
question is accompanied by a detailed rationale to reinforce learning and support exam preparation. This
examination emphasizes the application of evidence-based practice, regulatory compliance, and
professional judgment in diverse healthcare settings.
SECTION ONE: QUESTIONS 1–100
1. A 45-year-old female patient presents with fatigue, pallor, and glossitis. Laboratory findings reveal
microcytic anemia, elevated total iron-binding capacity, and low serum ferritin. Which intervention is
most appropriate as initial management?
A. Administer intramuscular vitamin B12 injections
B. Prescribe oral ferrous sulfate supplementation
,C. Recommend increasing dietary intake of leafy green vegetables only
D. Order parenteral iron dextran infusion
🟢B
🔴 Explanation: The presentation of microcytic anemia with elevated TIBC and low ferritin indicates iron
deficiency anemia. Oral ferrous sulfate is the standard first-line treatment due to its efficacy, safety, and
cost-effectiveness. Vitamin B12 deficiency causes macrocytic anemia, not microcytic. Dietary
modification alone is insufficient for established deficiency. Parenteral iron is reserved for severe cases
or when oral therapy is not tolerated.
2. A patient with type 2 diabetes mellitus is being educated about carbohydrate counting. Which
statement demonstrates proper understanding of glycemic index principles?
A. "Foods with a high glycemic index are always healthier choices"
B. "I should choose foods with a lower glycemic index to help control my blood sugar"
C. "Glycemic index is the only factor I need to consider in meal planning"
D. "All carbohydrates have the same effect on my blood glucose regardless of glycemic index"
🟢B
🔴 Explanation: Lower glycemic index foods produce a slower, more gradual rise in blood glucose,
which is beneficial for glycemic control in diabetes. High glycemic index foods cause rapid spikes in
blood sugar. Glycemic index is one of several factors to consider alongside portion size, total
carbohydrate content, and individual response patterns.
3. A 68-year-old male patient with chronic kidney disease stage 4 has a serum potassium level of 6.2
mEq/L. Which dietary modification should be prioritized?
A. Encourage consumption of bananas and oranges for vitamin C
B. Restrict intake of high-potassium foods such as potatoes and tomatoes
C. Increase consumption of dairy products for calcium supplementation
D. Recommend high-protein intake to prevent malnutrition
🟢B
🔴 Explanation: Hyperkalemia (potassium >5.5 mEq/L) in chronic kidney disease requires restriction of
high-potassium foods including potatoes, tomatoes, bananas, and oranges. Dairy products contain
significant potassium and should be limited. Protein restriction, not increased intake, is typically
indicated in advanced CKD to reduce urea production.
4. During a nutrition assessment, a patient reports taking warfarin for atrial fibrillation. Which dietary
consideration is most critical to address?
,A. Increasing intake of vitamin K-rich foods to enhance anticoagulation
B. Maintaining consistent intake of vitamin K-containing foods
C. Eliminating all vitamin K from the diet for optimal drug efficacy
D. Supplementing with vitamin K to prevent bleeding complications
🟢B
🔴 Explanation: Warfarin therapy requires consistent vitamin K intake to maintain stable international
normalized ratio (INR). Significant fluctuations in vitamin K consumption can alter anticoagulation
effectiveness. Complete elimination is unnecessary and potentially harmful. Increasing vitamin K would
antagonize warfarin's effects.
5. A pregnant woman in her first trimester asks about appropriate weight gain during pregnancy.
Based on her pre-pregnancy BMI of 22 kg/m², what is the recommended total weight gain range?
A. 11–20 pounds
B. 25–35 pounds
C. 15–25 pounds
D. 28–40 pounds
🟢B
🔴 Explanation: For a woman with normal pre-pregnancy BMI (18.5–24.9 kg/m²), the recommended
total weight gain is 25–35 pounds (11.5–16 kg). Underweight women should gain 28–40 pounds,
overweight women 15–25 pounds, and obese women 11–20 pounds.
6. Which laboratory value is the most sensitive indicator of early protein-energy malnutrition?
A. Serum albumin
B. Prealbumin
C. Total protein
D. Hemoglobin
🟢B
🔴 Explanation: Prealbumin has a short half-life (2–3 days) and responds rapidly to changes in
nutritional status, making it the most sensitive indicator for early detection of protein-energy
malnutrition. Serum albumin has a longer half-life (18–21 days) and reflects chronic status. Total protein
and hemoglobin are less specific indicators.
7. A patient with celiac disease is reviewing food labels. Which ingredient indicates a product is
unsafe for consumption?
A. Corn starch
B. Modified food starch derived from wheat
, C. Rice flour
D. Potato starch
🟢B
🔴 Explanation: Modified food starch derived from wheat contains gluten and is unsafe for individuals
with celiac disease. Corn starch, rice flour, and potato starch are gluten-free alternatives. Patients must
carefully read labels to identify hidden sources of gluten.
8. A 55-year-old male patient with hypertension is advised to follow the DASH diet. Which dietary
pattern best aligns with DASH recommendations?
A. High sodium, high potassium, high calcium
B. Low sodium, high potassium, high calcium
C. High sodium, low potassium, low calcium
D. Low sodium, low potassium, high magnesium
🟢B
🔴 Explanation: The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes low sodium
intake combined with high intake of potassium, calcium, and magnesium. This combination has been
shown to effectively lower blood pressure through multiple mechanisms including vasodilation and
reduced vascular resistance.
9. A patient with congestive heart failure is prescribed furosemide. Which nutrient deficiency is most
likely to develop with long-term use?
A. Iron deficiency
B. Potassium deficiency
C. Calcium deficiency
D. Vitamin B12 deficiency
🟢B
🔴 Explanation: Furosemide is a loop diuretic that increases urinary excretion of potassium, potentially
leading to hypokalemia. Patients on long-term furosemide therapy should be monitored for potassium
depletion and may require potassium supplementation or dietary modification to maintain adequate
levels.
10. An infant's length and weight measurements fall below the 5th percentile on growth charts. The
pediatrician suspects failure to thrive. Which intervention should be prioritized?
A. Immediate initiation of total parenteral nutrition
B. Comprehensive nutrition assessment including feeding history
