Question #1 Is the following statement true or false?
Exercise programs to increase strength and endurance in the older adult population may help delay the onset of the age-related functional consequences of decreased strength and endurance<br>
Exercise programs to increase strength and endurance in the older adult population may help delay the onset of the age-related functional consequences of decreased strength and endurance<br>
09
Answer to Question #1 True
Age-related changes in skeletal muscles, which are controlled by motor neurons, directly affect all activities of daily living. The end result of these age-related changes is a decline in motor function and a loss of strength and endurance, even in healthy older adults. Exercise programs to increase strength and endurance may help delay the onset of the age-related consequences of disability and loss of function<br>

11
Answer to Question #2 C. Osteoporosis can cause serious negative functional consequences even in the absence of additional risk factors
Osteoporosis is a gradual loss of bone mass that affects all adults to some degree and is strongly associated with low-trauma fractures in older adults. Osteoporosis is classified as primary when it is associated with age-related changes and as secondary when it is caused by medications or pathologic disturbances<br>

Question #3 Which statement related to risk factors for falls and the older adult is true?
Falls are most often the result of an isolated risk factor
The risk of falling increases in proportion to the number of risk factors
Risk factors for falls do not vary according to the environment
Functional abilities of the older adult are not considered a risk factor for falls<br>

16
Answer to Question #3 B. The risk of falling increases in proportion to the number of risk factors
Falls are the result of a combination of risk factors rather than one isolated risk factor, and the risk of falls increases in proportion to the number of risk factors<br>

Question #4 Which statement related to musculoskeletal function and the older adult population is true?
There is a greater decline in muscle strength in the upper extremities
Diminished muscle strength is attributed primarily to age-related loss of muscle mass
Older adults experience muscle fatigue after longer periods of exercise than do younger adults
Lifelong patterns of exercise and activity have little effect on muscle strength<br>

20
Answer to Question #4 B. Diminished muscle strength is attributed primarily to age-related loss of muscle mass
Beginning at about the age of 40 years, muscle strength declines gradually, resulting in an overall decrease of 30% to 50% by the age of 80 years, with a greater decline in muscle strength in the lower extremities than in the upper extremities<br>

27
Answer to Question #5 B. Calcium supplementation lowers the rate of fractures in older adults
A recent report from the U.S. Surgeon General recommended a pyramidal treatment approach to osteoporosis that includes physical activity, fall prevention, and supplementation with calcium and vitamin D as the foundation for fracture prevention. Absorption of calcium supplements is optimal at not more than 600 mg per dose<br>
