Nursing Elites

1. 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.

2. Which of the following is the most important risk factor for development of Chronic Obstructive Pulmonary Disease?

• A. Cigarette smoking
• B. Occupational exposure
• C. Air pollution
• D. Genetic abnormalities

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. When rickets occurs, how is the alveolar bone affected compared to other bones in the body?

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. When rickets occurs, the alveolar bone is affected similar to other bones in the body, with the trabeculae of the alveolar bone also weakening. In addition to damaged alveolar bone caused by vitamin D deficiency, dental changes include delayed dentition and small molars. The other choices are incorrect because both statements provided are accurate based on the effects of rickets on the alveolar bone.

4. What is the term for mobilizing people to become aware of their own problems and to take action to solve them?

• A. Community Organizing
• B. Family Nursing Care Plan
• C. Nursing Intervention
• D. Nursing Process

Correct answer: A

Rationale: The correct answer is Community Organizing. This involves engaging and mobilizing individuals in a community or group to take action for the mutual benefit or to solve common problems. The options 'Family Nursing Care Plan', 'Nursing Intervention', and 'Nursing Process' are incorrect as these terms refer to specific nursing practices and methods, not the broader action of mobilizing and engaging a community to solve its own problems. Moreover, the provided rationale does not match the original question and correct answer. It instead describes the proactive and preventative nature of nursing care, which is unrelated to the concept of community organizing.

5. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.
