Correct Answer: B

Rationale: Correct Answer: B Rationale: The thymus gland is responsible for producing T-cells, crucial for immune responses. As individuals age, the thymus gland shrinks and becomes less efficient, reducing the production of new T-cells. This decline in T-cell production weakens the immune response in older adults, making them more susceptible to infections. Therefore, choice B is correct. Summary of Incorrect Choices: A: Aging does not increase the production of white blood cells. In fact, the immune system may weaken with age due to a decline in key immune cells. C: Aging does not improve the body's ability to recognize and fight off pathogens. Instead, it often leads to a decline in immune function. D: While some inflammatory responses may increase with age, excessive inflammation can actually be harmful and contribute to age-related diseases, rather than providing protection.

Correct Answer: B

Rationale: The correct answer is B: Continuity theory. This theory suggests that as individuals age, they strive to maintain a sense of consistency in their activities, interests, and relationships. In this scenario, both the older woman and man are adapting their lifestyles to maintain a sense of continuity with their past selves. The woman continues to engage in social activities, reflecting her outgoing nature, while the man maintains his solitary habits but explores new interests, such as creative writing, to fulfill his need for personal growth. A: Activity theory focuses on the idea that continued engagement in activities leads to a higher quality of life in old age. While the older woman's active engagement aligns with this theory, the older man's solitary activities do not fully support this concept. C: Social exchange theory emphasizes the balance of costs and benefits in social relationships. This theory is not directly applicable to the scenario as it does not address the individuals' personal activities and interests. D: Disengagement theory suggests that older adults gradually withdraw

Correct Answer: D

Rationale: The correct answer is D, Standards of gerontological nursing practice, as the ANA Scope and Standards of Gerontological Nursing (2010) specifically outlines the accepted standards and guidelines for gerontological nursing practice. This document does not focus on skills and knowledge (Choice A), levels of practice (Choice B), or certification requirements (Choice C), but rather on setting the standards and expectations for gerontological nursing care. It is essential for nurses to adhere to these standards to provide high-quality care to older adults.

Correct Answer: C

Rationale: The correct answer is C because it highlights a common issue in nursing education where gerontological nursing content is often underrepresented, with less than 25% of the curriculum dedicated to geriatric care. This is accurate as many nursing programs prioritize other areas over gerontology. A is incorrect as gerontological nursing integration has historically been lacking in nursing curricula. B is incorrect because undergraduate programs often lack extensive coverage of gerontological nursing compared to other specialties like psychiatric nursing. D is incorrect as accreditation does not guarantee specific proportions of gerontological nursing content in the curriculum. Thus, choice C is the most accurate statement regarding gerontological nursing education.

Correct Answer: C

Rationale: The correct answer is C: Being adequately nourished. Malnutrition weakens the immune system, making individuals more susceptible to infections like tuberculosis. Diabetes (A), living in crowded institutions (B), and immunosuppression (D) all lower immunity, increasing the risk of developing TB. In summary, adequate nutrition is not a risk factor for TB in the elderly, while diabetes, institutional living, and immunosuppression are.
