1. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?

• 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 indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.

2. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

• A. vitamin B12
• B. folate
• C. niacin
• D. vitamin B6

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.

3. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

4. What are the contraindications for using MI Paste?

• A. Children under six
• B. Individuals with a milk casein allergy
• C. Pregnant women
• D. Both A and B

Correct answer: D

Rationale: MI Paste is contraindicated in children under six and in individuals with a milk casein allergy. The reason is that MI Paste contains casein phosphopeptide, which is derived from milk. Therefore, it may cause allergic reactions in those who are sensitive to milk proteins. Pregnant women (Choice C) are not contraindicated for using MI Paste unless they have a known allergy to milk casein. Hence, the correct answer is 'D: Both A and B'.

5. Causes of acute renal failure include:

• A. chronic renal failure
• B. uncontrolled diabetes mellitus
• C. recurrent urinary tract infections
• D. severe injury such as extensive burns

Correct answer: D

Rationale: The correct answer is D. Severe injuries, like extensive burns, can cause acute renal failure due to shock, reduced blood flow to the kidneys, and tissue damage. Choices A, B, and C are incorrect because chronic renal failure, uncontrolled diabetes mellitus, and recurrent urinary tract infections are more likely to contribute to chronic kidney disease rather than acute renal failure.
