1. 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.

2. Which of the following is a poor food source of iron?

• A. Dried fruits
• B. Cheese
• C. Clams
• D. Legumes

Correct answer: B

Rationale: Iron is an essential nutrient for the body, and while it can be found in many different types of foods, the amounts can vary significantly. Cheese, while a good source of other nutrients like calcium and protein, is not a particularly rich source of iron. On the other hand, clams, legumes, and dried fruits are known to contain higher levels of iron. Therefore, among the provided choices, cheese is considered a poor source of iron. It's important to note that a balanced diet should include a variety of foods to ensure the intake of all necessary nutrients.

• A. Make an incident report
• B. Call security to report the incident
• C. Wait for 2 hours before reporting

4. A person who consumes mostly pre-packaged meals is likely consuming too much ____.

• A. iron

5. A client is on a 2,000-calorie American Diabetes Association (ADA) diet and substitutes whole milk with skim milk. Which of the following items can the client add to the oatmeal on his breakfast tray?

• A. One 1/8 teaspoon of salt
• B. One ounce of raisins
• C. One tablespoon of low-fat margarine
• D. One teaspoon of brown sugar

Correct answer: B

Rationale: The correct answer is one ounce of raisins. Raisins are a healthy option to add to oatmeal as they provide natural sweetness without added sugars. They are a good source of fiber and essential nutrients. Option A, one 1/8 teaspoon of salt, is not necessary for flavoring oatmeal. Option C, one tablespoon of low-fat margarine, may add unnecessary fat to the meal. Option D, one teaspoon of brown sugar, adds extra sugar, which should be limited in a diabetes-friendly diet.
