Correct Answer: B

Rationale: The correct answer is B. Decreased hearing in older individuals can lead to increased danger as they may not be able to hear important warning sounds like smoke or security alarms. This can compromise their safety and well-being. A is incorrect because decreased hearing may lead to increased stressful interactions due to difficulties in communication. C is incorrect because decreased hearing can actually increase danger when driving or walking in traffic as the individual may not be able to hear car horns or other traffic sounds, leading to potential accidents. D is incorrect because decreased hearing can contribute to an increased risk of falls due to decreased awareness of environmental sounds and hazards.

Correct Answer: C

Rationale: The correct answer is C because regularly reviewing and adjusting medications can help minimize adverse effects of polypharmacy in older adults. This approach ensures that the medications are appropriate, necessary, and not causing harm. A: Encouraging herbal supplements is not a recommended approach as they can interact with prescription medications. B: Prioritizing over-the-counter medications may not address the complexities of polypharmacy and can still contribute to drug interactions. D: Limiting patient discussions about medications can lead to misunderstandings and non-adherence.

Correct Answer: A

Rationale: The correct answer is A because social aging refers to changes in a person's roles and relationships as they age. Retiring from a job is a significant social change that typically accompanies aging. This indicates a shift in the man's social status and activities, which aligns with the concept of social aging. B, C, and D are incorrect because taking multiple medications, using a walker, and celebrating a 65th birthday are not direct indicators of social aging. While these factors may be related to aging, they do not specifically address the social aspects of aging, which is the focus of the question.

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 because Mezey and Fulmer (2002) justify gerontological nursing research by emphasizing that it positively influences outcomes from nursing care. This is supported by evidence showing how research in gerontological nursing can lead to improved quality of care for older adults. Other choices are incorrect: A is not directly supported by the justification provided by Mezey and Fulmer (2002), C is too specific and not the main focus of their justification, and D is not mentioned in the justification and does not address the impact of research on nursing care outcomes.
