Correct Answer: C

Rationale: The correct answer is C: Coordinating members of the health care team. This demonstrates leadership as the nurse is taking charge of organizing and communicating with various healthcare professionals to ensure the best care for the older patient. By collaborating with the wound care team, the nurse shows effective coordination and communication skills, which are crucial in managing complex cases in older adults. Assessing older adults effectively (choice A) is important but does not specifically address leadership in coordinating care. Facilitating access to eldercare programs (choice B) is important but does not directly demonstrate leadership in coordinating care. Empowering older adults to manage chronic illness (choice D) is important for patient education but does not directly show leadership in coordinating the healthcare team.

Correct Answer: B

Rationale: The correct answer is B because health disparity refers to variations in health outcomes among different groups due to factors such as socioeconomic status, race, ethnicity, etc. This definition accurately captures the essence of health disparity as it highlights the unequal distribution of health outcomes. Choice A is incorrect because it refers to cultural elimination, which is not the definition of health disparity. Choice C is incorrect as it talks about differences in expected and actual incidence, not health outcomes among groups. Choice D is incorrect as it focuses on values and perspectives rather than health outcomes.

Correct Answer: A

Rationale: The correct answer is A: Decreased manual dexterity and inability to hold a toothbrush. As people age, they may experience decreased hand strength and motor skills, making it difficult to hold and manipulate objects like a toothbrush. This can lead to a decline in oral hygiene practices. Malocclusion of teeth (B) does not directly impact the ability to brush teeth. Decrease in taste acuity (C) may affect appetite but not tooth brushing habits. Lack of dental insurance (D) is a financial barrier and may affect access to dental care, but it does not directly impact the physical ability to brush teeth.

Correct Answer: B

Rationale: The correct answer is B because tuberculosis is an infectious bacterial disease that primarily affects the lungs. Clients taking immunosuppressant medications have weakened immune systems, making them more susceptible to developing active tuberculosis. This is due to the fact that the immune system is less able to fight off the bacteria causing tuberculosis. Choices A, C, and D are incorrect because tuberculosis is not spread by persons with positive skin tests and no symptoms, it is caused by bacteria (Mycobacterium tuberculosis) not a virus related to HIV, and it typically causes weight loss and not weight gain in the early stages.

Correct Answer: C

Rationale: The correct answer is C: Age-stratification theory. This theory suggests that age is a powerful determinant of social organization. In the given scenario, the retirement community is structured based on age groups, indicating stratification by age. This separation aligns with the concept of age-based social hierarchies and differing opportunities and resources based on age. Choice A (Role theory) focuses on how individuals adapt to social roles as they age, which is not directly reflected in the scenario. Choice B (Disengagement theory) posits that aging individuals withdraw from societal roles, which is not evident in the active engagement of residents in different age-specific communities. Choice D (Social exchange theory) emphasizes the relationships individuals form based on rewards and costs, which is not the primary focus in the scenario compared to the age-based stratification.
