What is the primary reason that older adults often experience adverse drug reactions?
- A. Their body metabolizes drugs faster than younger adults
- B. They typically take fewer medications
- C. They have slower renal and hepatic function
- D. They have better immune function
Correct Answer: C
Rationale: The correct answer is C because older adults often experience adverse drug reactions due to their slower renal and hepatic function. This leads to a decreased ability to clear drugs from the body efficiently, increasing the risk of drug accumulation and toxicity. Choice A is incorrect because aging typically results in slower drug metabolism, not faster. Choice B is also incorrect as older adults tend to take more medications, increasing the likelihood of drug interactions and adverse reactions. Choice D is incorrect because aging is associated with a decline in immune function, making older adults more susceptible to adverse drug reactions.

On which biological theory of aging is the prevention of telomere shortening based?
- A. Genetic research
- B. Caloric restriction
- C. Oxidative stress
- D. Cross-link
Correct Answer: A
Rationale: The correct answer is A: Genetic research. Telomere shortening is primarily based on the theory of cellular senescence, which is related to genetic research. Telomeres are protective caps at the end of chromosomes that shorten with each cell division. Genetic research has shown that telomere shortening is associated with aging and age-related diseases. Caloric restriction, oxidative stress, and cross-link theories of aging are not directly linked to telomere shortening. Caloric restriction focuses on extending lifespan by reducing calorie intake, oxidative stress theory suggests that aging is caused by cumulative damage from reactive oxygen species, and cross-link theory emphasizes the accumulation of non-reversible bonds between molecules as a cause of aging.
What is the most common type of dementia in older adults?
- A. Alzheimer's disease
- B. Vascular dementia
- C. Lewy body dementia
- D. Frontotemporal dementia
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.
An older adult who lives in an assisted living facility tells a nurse that she is engaged in life review. The nurse understands which of the following about life review?
- A. Life review is only useful at the very end of an individual’s life.
- B. Life review and reminiscence are the same phenomenon.
- C. Life review is a highly personal activity.
- D. Life review can help an individual change course or set new goals.
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.
The nurse is providing instructions to a nursing assistant regarding care of an older client with hearing loss. The nurse tells the assistant that clients with a hearing loss:
- A. Respond to low pitched tones.
- B. Have difficulty hearing any frequency of sound.
- C. Need assistance with lip-reading only.
- D. Respond to high-pitched tones more clearly.
Correct Answer: A
Rationale: The correct answer is A because clients with hearing loss typically have difficulty hearing high-pitched tones, making it easier for them to respond to low-pitched tones. Low-pitched tones are easier for individuals with hearing loss to perceive due to the nature of hearing loss affecting the ability to hear higher frequencies. Choice B is incorrect as it is a generalization that does not consider the specific nature of hearing loss. Choice C is incorrect because individuals with hearing loss may require various forms of assistance beyond just lip-reading. Choice D is incorrect as individuals with hearing loss generally struggle more with high-pitched tones.
The nurse is teaching a client with COPD about proper use of an inhaler. What should the nurse emphasize?
- A. Use the inhaler only when you feel short of breath.
- B. Inhale deeply before activating the inhaler.
- C. Inhale rapidly after activating the inhaler.
- D. Use the inhaler as often as possible for maximum benefit.
Correct Answer: B
Rationale: The correct answer is B because inhaling deeply before activating the inhaler ensures proper medication delivery to the lungs. This allows the medication to reach the affected areas efficiently. Choice A is incorrect because inhalers are often used preventatively, not just when short of breath. Choice C is incorrect as inhaling rapidly may not allow the medication to be effectively deposited in the lungs. Choice D is incorrect because using the inhaler excessively can lead to overuse and potential side effects.
