1. 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.
2. A client with anorexia undergoing radiation therapy is being taught by a nurse. Which instruction should the nurse include in the teaching?
- A. Limit high-calorie supplements to between meals
- B. Avoid overeating during your 'good' days
- C. Eat hot foods instead of cold foods
- D. Consume nutrient-dense foods first
Correct answer: D
Rationale: The correct instruction for a client with anorexia undergoing radiation therapy is to consume nutrient-dense foods first. This ensures that the client receives the necessary calories and nutrients. Option A is incorrect because high-calorie supplements should not be limited but rather incorporated wisely into the diet. Option B is incorrect as overeating is not recommended regardless of the type of day. Option C is incorrect as there is no specific preference for hot foods over cold foods in managing anorexia during radiation therapy.
3. Which food is most likely to be included in a low-fiber diet?
- A. Broccoli
- B. Ripe Bananas
- C. Onions
- D. Whole-Grain Bread
Correct answer: B
Rationale: A low-fiber diet is generally recommended for individuals who need to restrict their intake of dietary fiber for health reasons. Ripe bananas are low in fiber and easy to digest, making them an ideal choice for a low-fiber diet. On the other hand, broccoli, onions, and whole-grain bread are high in fiber. Therefore, they are less suitable for a low-fiber diet as they could cause digestive discomfort or exacerbate certain health conditions. Ripe bananas, being low in fiber, are the most appropriate choice for a low-fiber diet.
4. 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.
5. Each statement is true of vitamin K, except one. Which is the exception?
- A. Vitamin K is produced in the gut.
- B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
- C. Vitamin K maintains prothrombin levels.
- D. Vitamin K absorption increases with high levels of vitamin E supplementation.
Correct answer: D
Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.
