SECTION ONE: QUESTIONS 1–100
Question 1
A dietetic technician is assessing a 65-year-old patient with type 2 diabetes who has recently been prescribed a
new medication. Which laboratory value is MOST important to monitor for potential drug-nutrient interaction?
A. Serum creatinine
B. Hemoglobin A1C
C. Fasting blood glucose
D. Serum potassium
🟢 Correct answer: D
, 🔴 RATIONALE: Serum potassium is critical to monitor because certain diabetes medications (particularly
ACE inhibitors and some oral antihyperglycemics) can affect potassium levels, leading to hypokalemia or
hyperkalemia. While A1C and blood glucose measure diabetes control, they do not reflect drug-nutrient
interactions.
Question 2
Which nutrient is MOST likely to be deficient in a strict vegan diet if not carefully planned?
A. Vitamin C
B. Iron
C. Vitamin B12
D. Fiber
🟢 Correct answer: C
🔴 RATIONALE: Vitamin B12 is naturally found only in animal products, making strict vegans at high risk for
deficiency without fortified foods or supplements. Iron, vitamin C, and fiber can all be obtained adequately from
plant sources.
Question 3
In a food service operation, what is the PRIMARY purpose of implementing a HACCP plan?
