1. Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements true or false?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

2. The substance that is most supportive of bones and teeth is:

• A. Hemoglobin
• B. Collagen
• C. Insulin
• D. Pepsin

Correct answer: B

Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.

3. Which type of medication is most likely to induce xerostomia?

• A. Antibiotics
• B. Diuretics
• C. Local anesthetics
• D. Anticholinergics

Correct answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.

4. Which of the following foods or beverages would offer the most nutrients per calorie?

• A. chicken
• B. wine
• C. white bread
• D. broccoli

Correct answer: D

Rationale: Broccoli is indeed the correct answer. Broccoli is considered nutrient-dense, meaning it provides a significant amount of essential nutrients like vitamins, minerals, and fiber while being relatively low in calories. On the other hand, choices A, B, and C are not as nutrient-dense as broccoli. Chicken can be nutritious but may vary in nutrient content depending on the cut and preparation method. Wine, although containing antioxidants like resveratrol, is not a significant source of essential nutrients. White bread is often low in nutrients and fiber compared to whole grain options, making it less nutrient-dense than broccoli.

5. The recommended daily fluid intake of patients maintained using hemodialysis is:

• A. 150 mL plus the volume of urinary output
• B. 500 mL plus the volume of urinary output
• C. 1000 mL plus the volume of urinary output
• D. 1500 mL plus the volume of urinary output

Correct answer: C

Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.
