1. What differentiates one amino acid from another?

• A. The amine group
• B. The acid group
• C. The side chain
• D. None of the above

Correct answer: C

Rationale: The side chain, also known as the R group, is what differentiates one amino acid from another. It imparts unique properties to each amino acid, thereby influencing their roles and functions in proteins. The amine group (Choice A) and the acid group (Choice B) are components of all amino acids and do not cause the differences among various amino acids. Choice D is incorrect as it suggests that none of the given options account for the differences, which is not true as the side chain does.

2. In a patient with osteoporosis, which mineral is essential to prevent further bone loss?

• A. Iron
• B. Phosphorus
• C. Magnesium
• D. Calcium

Correct answer: D

Rationale: Calcium is crucial in preventing bone loss in patients with osteoporosis.

3. A client is being taught about foods to include in a low-fiber diet. Which statement indicates the client understands the teaching?

• A. "A fresh pear would be a good snack option."?
• B. "I can prepare refried beans for supper."?
• C. "Bran cereal would be a good breakfast choice."?
• D. "I should choose white rice as a side dish."?

Correct answer: D

Rationale: The correct answer is "I should choose white rice as a side dish." In a low-fiber diet, foods that are low in fiber are recommended to reduce gastrointestinal irritation. White rice is a low-fiber option suitable for this diet. Choices A, B, and C are high-fiber options and not suitable for a low-fiber diet. A fresh pear, refried beans, and bran cereal are all high in fiber, which should be avoided in a low-fiber diet.

4. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

5. Match protease with its digestive action:

• A. breaks down carbs
• B. breaks down proteins
• C. breaks down lipids
• D. helps fat digestion

Correct answer: B

Rationale: Proteases are enzymes that break down proteins into smaller peptides and amino acids.
