DOMAIN 1: CARBOHYDRATE METABOLISM AND DIGESTION
1. Brandy's dad has type 2 diabetes and recently purchased a book about low
glycemic index diet that he believes will help improve his blood sugar control.
What is the American Diabetes Association's recommendation regarding the
glycemic index?
A. Glycemic index should be the primary factor in meal planning for diabetics
B. Low glycemic index foods should completely replace all other carbohydrates
C. For diabetes management, the total amount of carbs consumed is more
important than the GI of individual foods
D. Glycemic index is not relevant to diabetes management at all
,Answer: C
Rationale: The American Diabetes Association emphasizes that total carbohydrate
intake has a greater impact on blood glucose levels than the glycemic index of
individual foods. While GI can be a useful tool, it should not replace overall
carbohydrate counting for diabetes management.

2. Which of the following are classified as monosaccharides?
A. Maltose, sucrose, and lactose
B. Glucose, fructose, and galactose
C. Starch, glycogen, and cellulose
D. Sucrose, glucose, and fructose
Answer: B
Rationale: Monosaccharides are the simplest form of carbohydrates and include
glucose, fructose, and galactose. These single sugar molecules are the building
blocks for more complex carbohydrates.
-------------------------------------------------------------------------------
3. Which of the following are classified as disaccharides?
A. Glucose, fructose, and galactose
B. Starch, glycogen, and cellulose
C. Maltose, sucrose, and lactose
D. Glucose, sucrose, and maltose
Answer: C
Rationale: Disaccharides are composed of two monosaccharide units linked
together. Maltose (glucose+glucose), sucrose (glucose+fructose), and lactose
(glucose+galactose) are the three main disaccharides.
-------------------------------------------------------------------------------
4. Carbs typically comprise the largest proportion of total daily calorie
intake. Select all of the meals that contribute significantly to meeting carb
needs:
A. Bowl of chili with kidney beans
B. Bowl of ice cream with fresh blueberries on top
C. Bowl of whole wheat pasta with red sauce
D. Grilled chicken breast with steamed broccoli
Answer: A, B, C
Rationale: Kidney beans (legumes), ice cream with blueberries (dairy and
fruit), and whole wheat pasta (grains) are all significant sources of
,carbohydrates. Grilled chicken with broccoli provides primarily protein and
non-starchy vegetables with minimal carbohydrate content.

5. Lisa is a 19-year-old college student who recently began experiencing
symptoms of lactose intolerance. Select all dietary practices that can help her
meet her calcium needs without aggravating her lactose intolerance symptoms:
A. Eat hard cheeses and yogurt
B. Drink low-lactose or lactose-treated milk
C. Drink calcium-fortified soy milk
D. Take lactase pills before eating or drinking dairy foods
Answer: A, B, C, D
Rationale: All of these strategies can help individuals with lactose
intolerance maintain adequate calcium intake. Hard cheeses and yogurt contain
less lactose, lactose-free milk products are available, fortified soy milk
provides calcium, and lactase enzyme supplements can aid in digestion.
-------------------------------------------------------------------------------
6. True or false: Brandy's 7-year-old daughter was recently diagnosed with
ADHD. According to scientific evidence, she should not feed her daughter any
refined sugar products because sugar intake causes hyperactivity in children.
A. True
B. False
Answer: B (False)
Rationale: Scientific evidence does not support a causal link between sugar
consumption and hyperactivity in children. While excessive sugar intake can
contribute to other health issues, it is not established as a cause of ADHD
symptoms or hyperactive behavior.
-------------------------------------------------------------------------------
7. Match the following glucose levels with their correct diabetes or glycemic
categories:
A. 70-100 mg/dL
B. <70 mg/dL
C. 100-125 mg/dL
D. >126 mg/dL
1. Hypoglycemia
2. Normal fasting blood glucose
3. Pre-diabetes
, 4. Diabetes
Answer: A-2, B-1, C-3, D-4
Rationale: Normal fasting blood glucose is 70-100 mg/dL. Levels below 70
indicate hypoglycemia. Fasting glucose between 100-125 mg/dL indicates
pre-diabetes. Fasting glucose of 126 mg/dL or higher indicates diabetes.
-------------------------------------------------------------------------------
8. What is the adult/age 1-3 child RDA for carbohydrates?
A. 100 grams
B. 130 grams
C. 150 grams
D. 200 grams
Answer: B
Rationale: The Recommended Dietary Allowance (RDA) for carbohydrates for both
adults and children aged 1-3 is 130 grams per day. This amount is sufficient to
meet the brain's glucose requirements.
-------------------------------------------------------------------------------
9. Which of the following carbohydrates is found in plain, fat-free milk?
A. Sucrose
B. Maltose
C. Lactose
D. Glucose
Answer: C
Rationale: Lactose is the primary carbohydrate found in milk and dairy products.
It is a disaccharide composed of glucose and galactose. Plain, fat-free milk
contains lactose even though the fat has been removed.

10. In the human intestinal tract, cooked rice is broken down into ______
molecules that can be absorbed.
A. Fructose
B. Sucrose
C. Glucose
D. Galactose
Answer: C
Rationale: Cooked rice contains starch, which is broken down by digestive
enzymes into glucose molecules. Glucose is the primary absorbable form of
