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.

- A. pepsin
- B. salivary amylase
- C. CCK
- D. secretin

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.
3. Clients with type 2 diabetes are most likely to achieve metabolic control if they:
- A. lose weight
- B. use self-monitoring of blood glucose
- C. eliminate all dietary sugars

4. Age group categories within older adults are classified as 'young old,' 'old,' and 'oldest old,' the latter of which comprises adults aged _____.
- A. 70-80 years
- B. 75-84 years
- C. 80-90 years
- D. 85 years or older
Correct answer: D
Rationale: The 'oldest old' category includes adults aged 85 years or older. This age group faces unique health challenges and requires specialized care. Choices A, B, and C are incorrect as they do not fall within the age range specified for the 'oldest old' category.
5. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.
- A. witness
- B. primary caregiver
- C. health care agent
- D. state proxy
Correct answer: C
Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.
