How does sarcopenia impact functional independence in older adults?
- A. It leads to increased body fat and reduced muscle mass, hindering mobility.
- B. It results in diminished lung capacity, reducing the ability to perform daily activities.
- C. It causes joint stiffness, leading to pain and limited range of motion.
- D. It significantly affects balance and mobility, increasing the risk of falls.
Correct Answer: D
Rationale: The correct answer is D because sarcopenia, which is the age-related loss of muscle mass and strength, directly impacts balance and mobility in older adults. Muscle weakness from sarcopenia reduces stability and coordination, increasing the risk of falls. This affects functional independence as it limits the ability to perform daily activities safely. Choices A, B, and C are incorrect as sarcopenia primarily affects muscle mass and strength, not body fat, lung capacity, or joint stiffness.

A peak flow meter
- A. is used to administer inhaled medications in dry powder form
- B. gives feedback to determine whether the client is developing asthma symptoms
- C. is used to identify specific allergy trigger agents
- D. can only be used by a respiratory therapist or nurse with special education
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.
Which of the following best describes the concept of "cognitive reserve" in older adults?
- A. It refers to the brain's ability to compensate for damage through enhanced neurogenesis.
- B. It refers to the relationship between cognitive decline and physical health.
- C. It is the brain's ability to maintain function despite age-related changes and pathology.
- D. It is the process of developing new cognitive abilities later in life.
Correct Answer: C
Rationale: The correct answer is C: "It is the brain's ability to maintain function despite age-related changes and pathology." Cognitive reserve in older adults refers to the brain's ability to withstand age-related changes and pathology while maintaining cognitive function. This concept suggests that individuals with higher cognitive reserve may show fewer cognitive deficits even in the presence of brain damage or pathology.
Choice A is incorrect because cognitive reserve is not about compensating for damage through enhanced neurogenesis but rather about maintaining function despite changes.
Choice B is incorrect because cognitive reserve is not specifically about the relationship between cognitive decline and physical health; it focuses on maintaining cognitive function.
Choice D is incorrect because cognitive reserve is not about developing new cognitive abilities later in life but rather preserving existing cognitive function.
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.
What is the primary goal of the Program for All-Inclusive Care for the Elderly (PACE)?
- A. To provide intensive medical treatment for seniors
- B. To ensure nursing home placement for frail seniors
- C. To offer holistic care that allows older adults to live in the community
- D. To reduce healthcare costs for elderly populations
Correct Answer: C
Rationale: The correct answer is C: To offer holistic care that allows older adults to live in the community. PACE aims to provide comprehensive and coordinated care to help seniors remain independent in their homes and communities. This includes medical, social, and behavioral services. Choice A is incorrect as PACE focuses on holistic care rather than just intensive medical treatment. Choice B is incorrect as PACE aims to prevent nursing home placement by supporting older adults to live at home. Choice D is incorrect as while PACE may help reduce healthcare costs through preventive and coordinated care, the primary goal is to support seniors in living in the community.
An older patient who was just diagnosed with a terminal disease states, "All my life I attended church, but I am still worried about what will happen after death." The nurse's best response is which of the following?
- A. "The unknown may be frightening. Do you want to talk about this?"
- B. "Religious people know that God is a good God."
- C. "People that have had near-death experiences say it is peaceful."
- D. "You must feel good about attending church most of your life."
Correct Answer: A
Rationale: The correct answer is A: "The unknown may be frightening. Do you want to talk about this?" This response acknowledges the patient's fear and offers an opportunity for the patient to express their concerns. It shows empathy and encourages open communication.
Choice B is incorrect because it assumes all religious people share the same belief, which may not be the case for this patient. Choice C is incorrect as it imposes experiences of others onto the patient, which may not align with their beliefs or feelings. Choice D is incorrect as it assumes the patient's feelings without giving them a chance to express themselves.
