1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

2. Which organ produces and secretes bicarbonate ions and insulin?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

3. Which food is a reliable source of B12 for a pregnant vegan client?

• A. Soybeans
• B. Algae
• C. Fortified soy milk
• D. Sea vegetables

Correct answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.

4. Generally, patients who wear dentures have reduced masticatory efficiency. Mandibular implant-supported dentures can have positive effects on the clinical aspects of mastication and swallowing.

• 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: A

Rationale: Both statements are true. Patients who wear dentures typically experience reduced masticatory efficiency. Mandibular implant-supported dentures are known to have positive effects on the clinical aspects of mastication and swallowing, significantly improving chewing function. Option A is correct because both statements align with these facts. Option B is incorrect as both statements are true. Option C is incorrect as the second statement is also true. Option D is incorrect as the first statement is true.

5. Patients with congestive heart failure need to restrict their intake of:

• A. fiber
• B. sodium
• C. cholesterol
• D. saturated fat

Correct answer: B

Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.
