1. Does the hypothalamus control the feeling of hunger and satiety, and are fats the best nutrient in creating the feeling of satiety?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Yes, the hypothalamus plays a crucial role in regulating hunger and satiety. Fats are indeed known to be highly satiating nutrients, helping to create a feeling of fullness and satisfaction after a meal. Therefore, both statements are true. Choice B is incorrect because fats are indeed effective in promoting satiety.

2. In the management process, the periodic checking of the results of action to make sure that it coincides with the goal of the institution is termed as:

• A. Planning
• B. Evaluating
• C. Directing
• D. Organizing

Correct answer: B

Rationale: The correct answer is B: Evaluating. Evaluating involves the periodic checking of results to ensure they align with the institution's goals. Planning (choice A) is about setting goals and determining the actions required to achieve them. Directing (choice C) involves overseeing and guiding the activities of individuals or teams to accomplish goals. Organizing (choice D) is about arranging resources and tasks to achieve objectives. In the context of the management process described, evaluating best fits the action of checking results against goals.

3. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

4. All of the following are seen in a child with measles. Which one is not?

• A. Reddened eyes
• B. Coryza
• C. Pustule
• D. Cough

Correct answer: C

Rationale: Measles typically presents with symptoms like reddened eyes, coryza (inflammation of the mucous membrane in the nose), and cough. However, pustules are not a common symptom of measles. Pustules are more characteristic of conditions like chickenpox rather than measles. Understanding these distinctions is crucial for accurate diagnosis and appropriate treatment.

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.
