When preparing a presentation for a senior center about age-related musculoskeletal changes, which of the following changes should be included?
Decreased muscle mass
Thickened vertebral disks
Increased force of isometric contraction
Reduced chest width
The Correct Answer is A
Choice A rationale
Decreased muscle mass is a common age-related musculoskeletal change. As people age, they tend to lose muscle mass due to changes in muscle fiber and decreased physical activity. This can lead to weakness and decreased mobility.
Choice B rationale
Thickened vertebral disks are not typically an age-related change. Instead, the disks often become thinner and less flexible with age, which can lead to conditions like degenerative disk disease.
Choice C rationale
Increased force of isometric contraction is not an age-related musculoskeletal change. In fact, both isometric and isotonic muscle strength tend to decrease with age.
Choice D rationale
Reduced chest width is not typically an age-related musculoskeletal change. However, changes in posture and spinal curvature can affect the shape and function of the chest.

Correct Answer is C
Explanation
Choice A rationale
Decreased follicle-stimulating hormone is not the major cause of the onset of menopause and the resulting atrophy of the vulvar organs. The major cause is decreased estrogen.
Choice B rationale
Increased levels of prostaglandin are not the major cause of the onset of menopause and the resulting atrophy of the vulvar organs. The major cause is decreased estrogen.
Choice C rationale
Decreased estrogen is the major cause of the onset of menopause and the resulting atrophy of the vulvar organs. During perimenopause, less estrogen may cause the tissues of the vulva and the lining of the vagina to become thinner, drier, and less elastic or flexible.
Choice D rationale
Increased luteinizing hormone is not the major cause of the onset of menopause and the resulting atrophy of the vulvar organs. The major cause is decreased estrogen.
Correct Answer is B
Explanation
Choice B rationale
The normal respiratory rate for a newborn is between 30 and 60 breaths per minute. Therefore, a respiratory rate of 48 breaths per minute is within the expected reference range for a newborn.
