1. Which medical condition is characterized by symptoms such as oral candidiasis, hairy leukoplakia, herpetic ulcerations, Kaposi's sarcoma, xerostomia, and severe periodontal disease?

• A. Acquired Immunodeficiency Syndrome (AIDS)
• B. Acute Leukemia
• C. Anorexia Nervosa
• D. Bulimia

Correct answer: A

Rationale: Acquired Immunodeficiency Syndrome (AIDS) is known for a variety of oral manifestations such as oral candidiasis, hairy leukoplakia, herpetic ulcerations, Kaposi's sarcoma, xerostomia, and severe periodontal disease. These symptoms are not typically associated with acute leukemia, anorexia nervosa, or bulimia. Acute leukemia usually presents with symptoms like fatigue, frequent infections, and easy bruising. Anorexia nervosa and bulimia are eating disorders, thus their primary symptoms are primarily associated with eating habits and body weight, not oral health.

2. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.

• A. glucose
• B. monosaccharides
• C. galactose
• D. disaccharides

Correct answer: B

Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.

3. What are the potential consequences of damage to the stomach?

• A. Reduced digestion of carbohydrates
• B. Inability to produce or secrete bile
• C. Inability to produce or secrete gastric acid
• D. Increased ability to produce or secrete intrinsic factor

Correct answer: C

Rationale: Damage to the stomach can lead to a reduced ability to produce gastric acid (Choice C) and intrinsic factor, the latter of which is crucial for vitamin B12 absorption (Choice D). That's why these two choices are correct. The stomach doesn't play a direct role in the digestion of carbohydrates (Choice A) as this process primarily occurs in the small intestine with the help of pancreatic enzymes. Similarly, bile is produced by the liver and stored in the gallbladder, not the stomach, hence stomach damage wouldn't lead to an inability to produce or secrete bile (Choice B).

4. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.

• 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: Both statements are false. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.

5. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
