Question 1

Compared to the year 2000, by the year 2030 what will have happened to the number of people over the age of 65?

Accepted Answer

The number of people over the age of 65 is expected to double by 2030 compared to the year 2000, due to factors such as increased life expectancy and aging baby boomer generation.

Question 2

Research on postural sway in adults has determined which of the following?

Accepted Answer

Research indicates that declines in balance, as evidenced by increases in postural sway, can begin as early as age 30. This is contrary to the belief that such declines only occur in much older adults.

Question 3

By the year 2050, many regions of the world (e.g., Europe, Latin America, the Caribbean, North America, Oceania) will have a life expectancy of nearly:

Accepted Answer

By 2050, many regions of the world are projected to have a life expectancy of nearly 80 years, according to the World Health Organization.

Question 4

According to research on older adults, which of the following is true?

Accepted Answer

Movement time tends to decline with age, meaning it takes longer for older adults to physically respond to stimuli. This is due to various factors such as decreased muscle strength, slower nerve conduction speeds, and other age-related physiological changes.

Question 5

By what year will the number of children from birth to nine years of age be exceeded by the number of people over sixty years old?

Accepted Answer

According to a report by the United Nations, the number of people over sixty years old is expected to exceed the number of children from birth to nine years of age by 2030. This demographic shift is largely due to declining fertility rates and increased life expectancy around the world.

Question 6

What was found in balance-related research studies on adults aged 50 to 75?

Accepted Answer

General decreases were seen yearly in overall balance ability.

Question 7

Which of the following are examples of intrinsic falls?

Accepted Answer

Intrinsic falls are caused by factors within the individual, such as fatigue, dizziness, and disease, which affect their balance or physical condition leading to a fall.

Question 8

Recommendations for older adults who wish to compensate for reduced speed , strength, or endurance and maintain high levels of performance include:

Accepted Answer

All the options provided are valid recommendations for older adults aiming to maintain high levels of performance despite reductions in speed, strength, or endurance. Setting higher expectations can motivate continued effort and improvement, conserving energy by pacing helps manage limited resources, and focusing on accuracy over speed can ensure quality performance despite slower execution.

Question 9

Regarding falls, which of the following is true?

Accepted Answer

All of the statements are true.

Question 10

According to results from the Baltimore Longitudinal Study on walking among older people:

Accepted Answer

The Baltimore Longitudinal Study on walking among older people found that factors such as longer stride and cadence are more closely associated with walking speed declines than age itself, and that slower walking is associated with a greater number of falls. This suggests that the mechanics of walking and its changes are more indicative of mobility issues than age alone, and that these changes can lead to increased fall risk.

Question 11

For those over the age of eighty years, the drop-off rate movement activity participation is

Accepted Answer

The drop-off rate for movement activity participation for those over the age of eighty years is 3 percent per year.

Question 12

In research on fall-prevention programs, what was the minimum criterion determined for the duration of an effective fall-prevention program?

Accepted Answer

The answer of In research on fall-prevention programs, what was...

Question 13

Compared to 2011, the number of drivers over the age of 65 years, by 2020, will have increased to:

Accepted Answer

The answer of Compared to 2011, the number of drivers...

Question 14

Older adults are characterized by which of the following?

Accepted Answer

Older adults often experience a decline in cognitive and motor functions, which can affect their ability to program and execute rapid series of movements efficiently compared to their younger counterparts. This is part of the normal aging process and can impact various aspects of daily living.

Question 15

Which of the following is NOT a major cause of falls in older adulthood?

Accepted Answer

All the options listed (fatigue, improper clothing or attire, and medication) can contribute to falls in older adults, making none of them an incorrect choice.

Question 16

Which of the following is a major factor relating to declines in driving ability with old age?

Accepted Answer

The answer of Which of the following is a major...

Question 17

The Mobility Consequences Model depicts the series of events that lead to which of the following?

Accepted Answer

The Mobility Consequences Model specifically outlines how changes in an individual's driving behavior can lead to various consequences, focusing on the impacts and adjustments related to driving habits and transportation needs.

Question 18

Which of the following is an example of an instrumental activity of daily living (IADL)?

Accepted Answer

Taking medication is an example of an instrumental activity of daily living (IADL), which refers to more complex skills needed for independent living, such as managing medications, finances, transportation, and housekeeping. Activities like feeding oneself, rising from a chair, and getting in/out of bed are considered basic activities of daily living (ADLs), which are fundamental tasks needed for personal care.

Question 19

Comparing older men and women and falling, which of the following is true?

Accepted Answer

Men are more likely to die from a fall. Studies have shown that while women may fall more frequently than men, men are more likely to suffer fatal outcomes from falls. This is attributed to various factors, including differences in body composition, pre-existing health conditions, and the nature of the falls.

Question 20

Regarding driving trends with age, which of the following is true of drivers who are over the age of 25?

Accepted Answer

Drivers over the age of 25 are generally more experienced and tend to have fewer accidents overall, but when they are involved in accidents, they are statistically more likely to be involved in fatal accidents compared to younger drivers.
