Correct Answer: C

Rationale: The correct answer is C: Loss of a spouse or close family member. This is the most significant predictor of social isolation in older adults because losing a spouse or close family member can result in decreased social interactions and emotional support. This loss can lead to feelings of loneliness and isolation. Incorrect options: A: Lack of access to healthcare - While lack of access to healthcare can impact overall health, it is not the primary factor contributing to social isolation. B: Limited income and resources - Financial constraints can affect social activities, but they are not as impactful as losing a loved one. D: High levels of physical activity - While physical activity is important for overall well-being, it is not directly correlated with social isolation in older adults.

Correct Answer: A

Rationale: The correct answer is A because health refers to a state of physical, mental, and social well-being, encompassing attitudes and behaviors. Choice B is incorrect as previous generations did consider illness prevention. Choice C is incorrect as wellness and self-actualization can also be influenced by genetics and environment. Choice D is incorrect as wellness can still be achieved through various aspects even if one's health is compromised.

Correct Answer: C

Rationale: The correct answer is C: Life review is a highly personal activity. This is because life review involves reflecting on past experiences, relationships, and accomplishments, which are unique to each individual. It is a process of self-reflection and introspection that helps individuals make sense of their lives and find meaning. Option A is incorrect because life review can occur at any point in an individual's life, not just at the very end. Option B is incorrect as reminiscence focuses on recalling past events, while life review involves deeper reflection and analysis. Option D is incorrect because while life review can promote self-awareness, it is primarily a reflective process rather than a tool for setting new goals.

Correct Answer: A

Rationale: The correct answer is A: Alzheimer's disease. It is the most common type of dementia in older adults, accounting for around 60-80% of cases. Alzheimer's is characterized by the presence of beta-amyloid plaques and tau protein tangles in the brain, leading to memory loss and cognitive decline. Vascular dementia (B) is caused by impaired blood flow to the brain, Lewy body dementia (C) is characterized by abnormal protein deposits in the brain, and Frontotemporal dementia (D) affects the frontal and temporal lobes of the brain, leading to changes in behavior and personality. However, in older adults, Alzheimer's disease is the most prevalent form of dementia due to its widespread impact on memory and cognition.

Correct Answer: B

Rationale: The correct answer is B because a peak flow meter is used to monitor and measure the peak expiratory flow rate, which helps determine if the client is developing asthma symptoms such as airway constriction. It provides feedback on the client's lung function, helping to assess asthma control and guide treatment. Choices A, C, and D are incorrect because a peak flow meter is not used for administering medications, identifying allergy triggers, or limited to specific healthcare professionals.
