1. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

2. Which metabolic disease is characterized by poor healing, severe forms of periodontal disease, necrosis, xerostomia, and candidiasis?

• A. Hypopituitarism
• B. Diabetes mellitus
• C. Hyperthyroidism
• D. Renal disease

Correct answer: B

Rationale: Diabetes mellitus is the correct answer. It is associated with poor wound healing, severe periodontal disease, tissue necrosis, dry mouth (xerostomia), and an increased susceptibility to oral infections like candidiasis. Hypopituitarism, hyperthyroidism, and renal disease are not typically linked to the specific oral manifestations described in the question.

3. What type of drug therapy is typically administered immediately after a heart attack?

• A. Antilipemic drugs
• B. Corticosteroids
• C. Diuretics
• D. Thrombolytic drugs

Correct answer: D

Rationale: Thrombolytic drugs are typically administered immediately after a heart attack to dissolve the clot blocking the coronary artery and restore blood flow to the heart muscle. Antilipemic drugs are used to lower lipid levels and prevent atherosclerosis, but they are not typically administered immediately after a heart attack. Corticosteroids are used to reduce inflammation and suppress the immune response, which are not immediate concerns after a heart attack. Diuretics are used to reduce fluid build-up and lower blood pressure, but these are not the primary concerns immediately following a heart attack.

4. A patient on a low-sodium diet should avoid which of the following foods?

• A. Fresh fruits
• B. Unsalted nuts
• C. Canned soup
• D. Plain rice

Correct answer: C

Rationale: Canned soup is the correct answer. Canned soups are often high in sodium due to added salt and should be avoided on a low-sodium diet. Fresh fruits (Choice A) are typically low in sodium and a good choice for a low-sodium diet. Unsalted nuts (Choice B) are also low in sodium and can be included in a low-sodium diet. Plain rice (Choice D) is a low-sodium food and can be part of a low-sodium diet.

5. Stimulates secretion of bicarbonate ions and digestive enzymes from the pancreas to the small intestine:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin

Correct answer: D

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.
