1. 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.

2. Which statement indicates understanding of a low-fiber diet?

A. I can cut up carrots and celery sticks for my lunch.
B. I will eat a bran muffin for my mid-morning snack.
C. I will have oatmeal with skim milk for my breakfast.
D. I should choose canned peaches for my fruit serving.

Correct answer: D

Rationale: The correct answer is D because canned peaches are low in fiber compared to the other options provided. Option A contains high-fiber vegetables (carrots and celery), option B includes a bran muffin which is fiber-rich, and option C involves oatmeal which is also a good source of fiber. Therefore, choosing canned peaches aligns with a low-fiber diet.

3. In managing Type 2 diabetes, what is the most important dietary change?

A. Increase carbohydrate intake
B. Increase fiber intake
C. Increase protein intake
D. Reduce fat intake

Correct answer: B

Rationale: Increasing fiber intake can help regulate blood sugar levels in patients with Type 2 diabetes.

4. A client who follows the dietary laws of Orthodox Judaism is being cared for by a nurse. Which of the following meal choices should the nurse request for the client?

A. Turkey and cheese sandwich
B. Spaghetti with tomato sauce
C. Pork chop and applesauce
D. Scrambled eggs and bacon

Correct answer: B

Rationale: The correct meal choice for a client following the dietary laws of Orthodox Judaism is 'Spaghetti with tomato sauce.' Orthodox Judaism prohibits mixing meat and dairy and consuming pork. The other choices - 'Turkey and cheese sandwich' (mixing meat and dairy), 'Pork chop and applesauce' (contains pork), and 'Scrambled eggs and bacon' (mixing meat and dairy) - do not adhere to the kosher dietary laws.

5. Which lipid contains 3 fatty acids?

A. cholesterol
B. phospholipid
C. saturated
D. triglyceride

Correct answer: D

Rationale: The correct answer is 'D. triglyceride.' Triglycerides are composed of one glycerol molecule and three fatty acids, making them the primary form of stored fat in the body. Cholesterol (A) is a different type of lipid, phospholipids (B) have two fatty acids, and 'saturated' (C) refers to the structure of fatty acids, not a specific lipid containing 3 fatty acids.
