ACCP Nutrition Support Pharmacy Practice Exam
1. In nutritional assessment, which component is essential for determining a patient’s
nutritional status?
A) Dietary history
B) Family history
C) Genetic profile
D) Sleep patterns
Answer: A
Explanation: Dietary history directly reflects the patient’s food intake, making it a cornerstone of
nutritional assessment.
2. Which laboratory parameter is most useful in assessing protein-energy malnutrition?
A) Glucose level
B) Serum albumin
C) Serum sodium
D) Hemoglobin
Answer: B
Explanation: Serum albumin is widely used to evaluate protein status, although it can be
influenced by other factors.
3. What does body mass index (BMI) primarily assess in a nutritional evaluation?
A) Micronutrient deficiencies
B) Hydration status
C) Weight relative to height
D) Muscle mass distribution
Answer: C
Explanation: BMI is a calculated value that relates weight to height, serving as a screening tool
for underweight or overweight conditions.
4. Which anthropometric measurement is particularly useful for assessing central obesity?
A) Mid-upper arm circumference
B) Waist circumference
C) Thigh circumference
D) Calf circumference
Answer: B
Explanation: Waist circumference is a key indicator of central adiposity, which is linked to
metabolic risk.
,5. In the context of metabolism, what is the primary energy source during prolonged
fasting?
A) Carbohydrates
B) Proteins
C) Fats
D) Vitamins
Answer: C
Explanation: During prolonged fasting, the body increasingly relies on fat oxidation for energy.
6. How is the resting energy expenditure (REE) best estimated in clinical practice?
A) Using predictive equations
B) Direct measurement of blood pressure
C) Calculating BMI only
D) Assessing sleep quality
Answer: A
Explanation: Predictive equations such as the Harris-Benedict equation are commonly used to
estimate REE.
7. Which macronutrient is primarily responsible for providing structural components to
cells?
A) Carbohydrates
B) Lipids
C) Proteins
D) Minerals
Answer: C
Explanation: Proteins are the building blocks for tissues and enzymes, forming essential
structural components.
8. In a critically ill patient, why is it important to assess both energy and protein
requirements separately?
A) Because energy and protein are measured in the same unit
B) To ensure adequate supply for metabolic demands and tissue repair
C) To reduce the number of laboratory tests
D) Because protein requirements are negligible in critical illness
Answer: B
Explanation: Critical illness increases both energy expenditure and protein catabolism,
necessitating separate and precise assessments.
9. What is the primary role of micronutrients in metabolism?
A) To provide energy directly
B) To serve as coenzymes and cofactors
,C) To form cell membranes
D) To store genetic information
Answer: B
Explanation: Micronutrients, such as vitamins and minerals, are essential as coenzymes and
cofactors in many metabolic pathways.
10. Which electrolyte imbalance is most often associated with the refeeding syndrome in
malnourished patients?
A) Hyperkalemia
B) Hypophosphatemia
C) Hypercalcemia
D) Hypomagnesemia
Answer: B
Explanation: Hypophosphatemia is a hallmark of refeeding syndrome due to shifts in phosphate
during carbohydrate reintroduction.
11. In fluid management, what is the most reliable indicator of a patient’s hydration
status?
A) Skin turgor
B) Urine output
C) Blood pressure
D) Body temperature
Answer: B
Explanation: Urine output provides an objective measure of kidney function and hydration
status.
12. Which acid-base disorder is commonly seen in patients receiving parenteral nutrition?
A) Metabolic acidosis
B) Respiratory alkalosis
C) Metabolic alkalosis
D) Respiratory acidosis
Answer: A
Explanation: Metabolic acidosis may occur due to the accumulation of acids from nutrient
metabolism during PN.
13. Which test is most useful in evaluating a patient’s electrolyte balance?
A) Complete blood count (CBC)
B) Basic metabolic panel (BMP)
C) Liver function tests
D) Coagulation profile
, Answer: B
Explanation: A BMP includes key electrolytes like sodium, potassium, and chloride, making it
essential for electrolyte assessment.
14. How does the metabolism of carbohydrates primarily contribute to energy production?
A) Through beta-oxidation
B) Via glycolysis and the Krebs cycle
C) By deamination
D) Through direct ATP binding
Answer: B
Explanation: Carbohydrate metabolism involves glycolysis and the Krebs cycle to efficiently
generate ATP.
15. Which component of the nutritional assessment can best indicate long-term nutritional
status?
A) Serum prealbumin
B) Recent dietary recall
C) Hydration status
D) Blood pressure trends
Answer: A
Explanation: Serum prealbumin, with its short half-life, is sensitive to changes and can indicate
recent nutritional status, though for long-term status, additional markers are needed.
16. Which parameter is most effective for assessing muscle mass in nutritional
assessments?
A) Body weight
B) Mid-arm muscle circumference
C) Serum lipid profile
D) Bone mineral density
Answer: B
Explanation: Mid-arm muscle circumference is a specific measure to assess muscle mass and
nutritional reserves.
17. What is the clinical significance of a high respiratory quotient (RQ) in nutrition
support?
A) Indicates predominant fat metabolism
B) Suggests carbohydrate overfeeding
C) Reflects high protein intake
D) Shows balanced nutrient intake
Answer: B
Explanation: A high RQ (above 1.0) may indicate overfeeding carbohydrates, leading to
increased carbon dioxide production.
