1. What type of diet would most likely benefit a patient with cystic fibrosis?

• A. Low sodium
• B. Low fat
• C. Clear liquid
• D. High calorie, high protein

Correct answer: D

Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.

2. Which vitamin is also known as Niacin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

3. For a patient on a ketogenic diet, which macronutrient is primarily increased?

• A. Carbohydrates
• B. Protein
• C. Fats
• D. Fiber

Correct answer: C

Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.

4. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

5. 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.
