1. Which vitamin acts most like a hormone?

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

2. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

3. 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.

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.

4. Which ethnic group has the lowest rates of type 2 diabetes?

Correct answer: A

Rationale: Statistical data suggest that Caucasians generally have lower rates of type 2 diabetes compared to the other ethnic groups listed in the choices. This is not to say that Caucasians are immune to the disease, but rather that they have fewer reported instances. On the other hand, African Americans and Pacific Islanders are often identified as groups with a significantly higher risk and prevalence of type 2 diabetes. Asian Indians also exhibit higher rates compared to Caucasians. It is important to note that these are general trends observed in statistical data, and individual health outcomes can vary based on various factors such as lifestyle, diet, and genetics, among others. Therefore, the correct answer is A: Caucasians because they generally have the lowest rates of type 2 diabetes when compared to the other ethnic groups mentioned.

5. Before and after the operation, the operating suite is managed by the:

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.
