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.

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.
Identify the correct statement describing the abuse of elderly persons in the United States.
- A. Elder abuse is the most often reported form of domestic violence
- B. Statistically, neglect is the most common form of elder abuse
- C. Most cases of elder abuse are reported to the proper authorities
- D. Healthcare practitioners are only mandated to report verified, not suspected, cases of elder abuse
Correct Answer: B
Rationale: The correct answer is B: Statistically, neglect is the most common form of elder abuse. Neglect involves the failure to provide necessary care or assistance to an elderly person, making it a prevalent form of elder abuse. This is supported by research and studies on elder abuse cases.
A is incorrect because elder abuse is often underreported compared to other forms of domestic violence.
C is incorrect as many cases of elder abuse go unreported due to various reasons such as fear, shame, or lack of awareness.
D is incorrect as healthcare practitioners are mandated to report any suspected cases of elder abuse, not just verified cases, to protect the well-being of the elderly.
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.
Which action should the nurse take when addressing older adults?
- A. Speak in an exaggerated pitch.
- B. Use a lower quality of speech.
- C. Use endearing terms such as 'honey.'
- D. Speak clearly.
Correct Answer: D
Rationale: The correct answer is D: Speak clearly. This is important when addressing older adults as many may have hearing impairments. Speaking clearly helps ensure they can understand and follow instructions. Using an exaggerated pitch (A) may come across as patronizing. Using a lower quality of speech (B) can be perceived as disrespectful. Using endearing terms (C) may not be appropriate for all individuals and can be seen as condescending. In summary, speaking clearly is the most effective way to communicate respectfully with older adults.
Which of the following assessment findings would be most suggestive of deep vein thrombosis (DVT)?
- A. Bilateral calf tenderness after walking up a flight of stairs
- B. Swelling in one leg with pitting edema
- C. Shortness of breath after activity
- D. Two plus palpable pulses
Correct Answer: B
Rationale: The correct answer is B because swelling in one leg with pitting edema is a classic sign of DVT. Pitting edema suggests fluid accumulation due to compromised venous circulation, which is common in DVT. Bilateral calf tenderness (choice A) is more indicative of muscle strain. Shortness of breath (choice C) is suggestive of a pulmonary embolism, a complication of DVT. Two plus palpable pulses (choice D) indicate good arterial circulation, not DVT.
