1. Which enzyme digests fiber in the large intestine?

A. salivary amylase
B. pancreatic amylase
C. cellulase
D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. A patient who reports stomach ulcers should avoid all the following foods, except one. Which is the exception?

A. Proteins
B. Caffeine
C. Calcium
D. Wheat

Correct answer: D

Rationale: Patients with stomach ulcers are advised to avoid foods that can increase stomach acid levels, such as caffeine, proteins, and calcium. Wheat, on the other hand, is generally well-tolerated by individuals with ulcers as it does not stimulate gastric secretions. Therefore, the correct answer is D. Choice A (Proteins), B (Caffeine), and C (Calcium) are not recommended for patients with stomach ulcers due to their potential to exacerbate symptoms.

3. With which type of cancer is asbestos exposure most strongly associated?

A. Liver cancer
B. Peritoneal cancer
C. Skin cancer
D. Esophageal cancer

Correct answer: B

Rationale: Asbestos exposure is most strongly associated with peritoneal cancer, a type of cancer that affects the lining of the abdomen. While asbestos can potentially contribute to other types of cancer, there is a significant body of research indicating a robust correlation between asbestos exposure and peritoneal cancer. Asbestos exposure can also lead to mesothelioma, a cancer that affects the lining of the chest. The other options - liver cancer, skin cancer, and esophageal cancer - are not typically associated with asbestos exposure.

4. A client is being taught about following a low-cholesterol diet after coronary artery bypass grafting. Which of the following food choices reflects the client's understanding of these dietary instructions?

A. Liver
B. Milk
C. BEANS
D. Eggs

Correct answer: C

Rationale: Choosing beans as a food option indicates that the client understands the low-cholesterol diet instructions. Beans are a good source of fiber and plant-based protein, which can help lower cholesterol levels. On the other hand, liver and eggs are high in cholesterol and should be limited in a low-cholesterol diet. Milk, especially whole milk, can also be high in saturated fats and cholesterol, so it is not the best choice for a low-cholesterol diet.
