1. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

2. An imbalance of which nutrient may elicit delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: The correct answer is B: Iron. The provided extract mentions that iodine deficiency can cause delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter. Zinc, Sodium, and Potassium are not associated with these specific symptoms. Zinc deficiency can lead to other health issues but not the ones mentioned. Sodium and Potassium imbalances do not typically result in the symptoms described in the question.

3. 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.

4. Match amylase with its digestive action:

• A. breaks down carbs
• B. breaks down proteins
• C. breaks down lipids
• D. helps fat digestion

Correct answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.

5. Which nutrient is critical for wound healing and immune function?

• A. Vitamin B12
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.
