1. 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.

2. What is the function of the gallbladder?

• A. to store bile
• B. to produce bile
• C. to digest bile
• D. to modify bile to a liquid form

Correct answer: A

Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.

3. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?

• A. cleaning and disinfecting of utensils
• B. developing healthy menus
• C. controlling patient calorie intake
• D. prescribing diets for patients with swallowing problems

Correct answer: A

Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.

4. A nurse is instructing a group of clients regarding calcium-rich foods. Which of the following foods should the nurse include in the teaching as the best source of calcium?

• A. 1?2 cup ice cream
• B. 1 ounce Swiss cheese
• C. 1 cup milk
• D. 1 cup cottage cheese

Correct answer: D

Rationale: Cottage cheese is the best source of calcium among the options provided. It is rich in calcium and provides a significant amount per serving. 1 cup of cottage cheese contains more calcium compared to 1?2 cup of ice cream, 1 ounce of Swiss cheese, or 1 cup of milk. Ice cream is not a significant source of calcium and is often high in sugar and fat. Swiss cheese and milk contain calcium, but cottage cheese has a higher calcium content per serving, making it the best choice for meeting calcium needs.

5. A healthcare professional is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?

• A. BUN 8 mg/dL
• B. Hgb 15 g/dL
• C. Creatinine 0.8 mg/dL
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: A BUN level of 8 mg/dL indicates fluid volume excess in a client with heart failure. BUN (Blood Urea Nitrogen) levels can be low in fluid overload due to hemodilution, a common occurrence in heart failure. High levels of BUN usually indicate dehydration or impaired renal function, which are not the case in fluid volume excess. Choices B, C, and D are within normal ranges and do not specifically indicate fluid volume excess.
