1. What is the most significant dietary influence on the development of dental caries?

• A. Carbohydrates
• B. Vitamins
• C. Minerals
• D. Fats

Correct answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

2. A common side effect of diuretic medications is _____.

• A. dry mouth
• B. urinary tract infection
• C. increased taste perception
• D. nausea

Correct answer: A

Rationale: Diuretic medications can lead to dry mouth due to increased fluid loss through urination, reducing saliva production.

3. A nurse is reviewing blood glucose values for a client who is at risk for Diabetes Mellitus. Which of the following findings should the nurse report to the provider?

• A. 2-hour glucose tolerance test level 150 mg/dL
• B. Fasting blood glucose 70 mg/dL
• C. Glycosylated hemoglobin 5%
• D. Casual blood glucose 90 mg/dL

Correct answer: A

Rationale: The correct answer is A. A 2-hour glucose tolerance test level of 150 mg/dL is above the normal range and should be reported to the provider as it indicates impaired glucose tolerance. Choice B (Fasting blood glucose 70 mg/dL) is within the normal range. Choice C (Glycosylated hemoglobin 5%) is also within the normal range. Choice D (Casual blood glucose 90 mg/dL) is within the normal range and does not indicate impaired glucose tolerance.

4. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

5. Which vitamin deficiency is most likely to cause bleeding disorders?

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

Correct answer: C

Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.
