, Q1. A hospitalized patient with malnutrition and a serum albumin of 2.1 g/dL is
prescribed parenteral nutrition. Which laboratory value most critically requires
monitoring to prevent refeeding syndrome?
A. Serum potassium
B. Serum calcium
C. Serum magnesium
D. Serum phosphorus
Correct Answer: D. Serum phosphorus
Rationale: Refeeding syndrome is characterized by severe hypophosphatemia due to
intracellular shift of phosphate during anabolic processes. Monitoring phosphorus is
critical to prevent cardiac and respiratory complications. Potassium and magnesium also
drop but phosphorus is the hallmark. Calcium is not the primary concern.
Why Wrong:
A - Potassium does drop but is not the hallmark of refeeding syndrome.
B - Calcium levels are not the primary focus in refeeding syndrome.
C - Magnesium deficiency occurs but is not the defining characteristic.

Q2. In the United States, the Dietary Guidelines for Americans recommend that
added sugars be limited to less than what percentage of total daily caloric intake?
A. 5%
B. 10%
C. 15%
D. 20%
Correct Answer: B. 10%
Rationale: The 2020-2025 Dietary Guidelines for Americans recommend limiting added
sugars to less than 10% of total daily calories. This is based on evidence linking high
added sugar intake to chronic disease risk. The other percentages are not the official
recommendation.
Why Wrong:
A - 5% is stricter than the official recommendation.
C - 15% exceeds the recommended limit.
D - 20% is too high and not evidence-based.

2020-2025, 9th Ed.
Q3. Which combination of nutrition-focused physical exam findings is most indicative
of severe protein-energy malnutrition in an adult?
A. Temporal wasting, cheilosis, and peripheral edema
