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.

- A. Not be harmed
- B. Disclosure

Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
3. What is the most appropriate nutritional advice for a patient with hypertension?
- A. Increase salt intake
- B. Reduce fiber intake
- C. Increase potassium intake

4. Which is NOT a characteristic or function of lipids?
- A. Involved in energy metabolism and storage
- B. Provide insulation and protection
- C. Act as hormones that regulate the body
- D. Are hydrophilic
Correct answer: D
Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.
