Test 1 Flashcards
What is ageism?
A: Prejudice or discrimination against a particular age-group, especially the elderly.

Q: What are the good exercise prescription parameters for those with HTN, DM, OA?
A: HTN: Moderate aerobic exercise, 5-7 days/week. DM: 150 minutes of moderate exercise weekly. OA: Low-impact aerobic and strengthening exercises.
Q: What is the optimal exercise prescription for pre-frail and frail individuals?
A: Strength training 2-3 days a week, balance exercises, and moderate aerobic activity.
Q: Discuss the i-STRONGER program used in this study including who the program is for, the exercise parameters used, the results of the study, and the clinical significance.
A: For: Older adults at risk of frailty. Parameters: Progressive resistance and functional exercises. Results: Improved strength and mobility. Significance: Reduces frailty and improves functional capacity.
Q: What are the common characteristics of polypharmacy?
A: Use of 5 or more medications, increased risk of adverse reactions, and drug interactions.
Q: What is the impact of pharmacokinetic changes in older adults?
A: Slower metabolism and elimination of drugs, leading to prolonged effects and higher risk of toxicity.
Q: What are common adverse drug reactions (ADRs) experienced by older adults and which types of medications produce specific ADRs?
A: Sedation and dizziness (benzodiazepines), postural hypotension (antihypertensives), cognitive impairment (antidepressants).
Q: What are the normal age-related cellular immune changes that result in increased systemic inflammation?
A: Decline in T-cell function and increased pro-inflammatory markers.
Q: What is the proposed reason for these normal age-related changes?
A: Immunosenescence, where the immune system declines with age.
Q: What are the normal aging changes associated with the central nervous system?
A: Decreased brain volume, slower neural processing, and reduced neurotransmitter levels.
Q: How do the normal age-related changes of the central nervous system impact the function of an older adult?
A: Slower reaction times, reduced cognitive function, and impaired motor coordination.
Q: How do the normal age-related changes of the peripheral nervous system impact the function of an older adult?
A: Reduced motor control, slower reflexes, and higher fall risk.
Q: What is fiber (re)grouping?
A: Motor neurons reinnervate denervated muscle fibers, creating larger motor units.
Q: What are the normal aging changes associated with the peripheral nervous system?
A: Reduced nerve conduction velocity and loss of motor neurons.
Q: What are approaches to address total-body inflammation and what is the impact of exercise?
A: Anti-inflammatory diet, exercise reduces systemic inflammation and improves immune function.
Q: What are the typical first signs of illness in older adults?
A: Weakness, confusion, and loss of appetite.
Q: Describe the normal age-related sensory changes to vision in older adults.
A: Presbyopia, reduced contrast sensitivity, and narrower visual field.
Q: What are some compensatory measures that can be taken to address specific vision impairments?
A: Improved lighting, use of magnifiers, contrast enhancement.
Q: What are the common vision pathologies experienced by older adults and what is the impact on their vision/visual field?
A: Cataracts, glaucoma, macular degeneration; all result in reduced central or peripheral vision.
Q: Of the sensory impairments experienced by older adults, which one impacts balance the most?
A: Loss of proprioception.
Q: Does hearing decline with age?
A: Yes, presbycusis causes difficulty in hearing high-frequency sounds.
Q: What are some strategies a physical therapist can use when working with a patient with hearing impairment?
A: Use visual cues, face the patient while speaking, and reduce background noise.
Q: Which sensory changes have been linked to dementia?
A: Decline in both vision and hearing.
Q: What is sarcopenia and why does it occur?
A: Sarcopenia is the loss of muscle mass and strength, caused by aging, hormonal changes, and reduced physical activity.
Q: What physiologic changes contribute to the normal aging of muscle tissue?
A: Decrease in muscle fibers, reduced protein synthesis, and loss of motor units.
Q: What metabolic changes affect our musculature as we age?
A: Decreased mitochondrial efficiency, reduced insulin sensitivity, and slower energy metabolism.
Q: What physiologic changes contribute to the normal aging of the skeletal system?
A: Decreased bone density, slower bone remodeling, and reduced calcium absorption.
Q: What physiologic changes contribute to normal joint aging?
A: Thinning cartilage, reduced synovial fluid, and joint stiffness.
Q: What physiologic changes contribute to the normal aging of tendons?
A: Tendons become less elastic, heal slower, and have reduced collagen production.
Q: What physiologic changes contribute to the normal aging of cartilage?
A: Loss of water content, thinning, and increased brittleness of the cartilage.
Q: What physiologic changes contribute to the normal aging of the intervertebral discs?
A: Loss of water content, reduced disc height, and increased degeneration.
Q: What trends in joint range of motion are noted within the aging adult?
A: Decreased flexibility in most joints, particularly in the spine and hips.
Q: Which joints are not typically limited in range?
A: Shoulder flexion and extension tend to be less affected.
Q: What are the two most common fractures associated with osteoporosis?
A: Hip fractures and vertebral compression fractures.
Q: What are the key components of the history specific to the aging adult population?
A: Functional status, fall history, medications, and comorbid conditions.
Q: What movement or loading precautions exist for a patient with spinal stenosis? Why?
A: Avoid excessive extension and high-impact exercises to prevent nerve compression.
Q: When would you use the wall to occiput distance or plumb line assessment and what can it tell us as practitioners?
A: Used to assess thoracic kyphosis; a positive test may indicate vertebral fractures or postural changes.
Q: What movement or loading precautions exist for a patient with a medical diagnosis of osteoporosis? Why?
A: Avoid high-impact activities and excessive spinal flexion to reduce fracture risk.
Q: What is spinal stenosis and how is it classified?
A: Narrowing of the spinal canal, classified as either lumbar or cervical stenosis.
Q: What are the key findings associated with spinal stenosis?
A: Pain, numbness, and weakness in the legs or arms, relieved by flexion.
