Final Exam (includes outline & practice questions)

Final Exam (includes outline & practice questions) T/F Decreased size, number of cells in CNS (gyral atrophy), Ventricular dilation, and cerebral metabolic rate of O2 utilization decline are normal processes of aging in CNS. - ANSWERSTrue T/F Cortical neuronal loss is part of normal aging. - ANSWERSFalse! - not part of normal aging Areas where there is neuronal loss - ANSWERSThalamus, straitum, basal forebrain, hippocampus T/F Not all older adults are frail and not all frail older adults are disabled. - ANSWERSTrue T/F Frail older adults have decreased rates of survival as they age. - ANSWERSTrue Define frailty - ANSWERSDecreased ability to cope with acute stressors due to age-related physiological/functional decline T/F Frailty may be reversible via PT. - ANSWERStrue Typical characteristics in frailty - ANSWERSDecreased functional reserve Impairment in multiple physiological systems Reduced ability to regain physiological homeostasis after stressful event Older adult shows weakness, slowness, exhaustion, weight loss, grip strength in lowest 20%, walking time in lowest 20%, unintentional weight loss over 10 lbs in past week. How would you describe this patient? - ANSWERSFrail older adult (typical phenotype) Fried's frailty levels criteria What groups are there? - ANSWERSWeight loss Weakness Slowness Exhaustion Low physical activity Non frail: no criteria Pre frail: one or two criteria Frail: three or more criteria This model describes frailty as a dynamic state, where frailty is based on the tenuous balance between assets and deficits; this balance determines a person's ability to remain independent. - ANSWERSRockwood model/ Frailty index (FI)
