A nurse is educating a group of elderly patients about osteoarthritis.
Which statement by the nurse accurately explains a risk factor associated with osteoarthritis?

Osteoarthritis is indeed more common in older individuals, but it is not primarily due to genetic factors.

While genetics can play a role, the primary risk factor for osteoarthritis in older adults is wear and tear on the joints over time.

Choice B rationale:

Excessive weight is a well-established risk factor for osteoarthritis.

The rationale behind this is that carrying excess body weight puts additional stress on the joints, particularly the weight-bearing joints like the knees and hips.

This increased mechanical stress can lead to the degeneration of joint cartilage and the development of osteoarthritis.

Choice C rationale:

Osteoarthritis can be exacerbated by joint trauma, such as fractures, but it is not primarily caused by trauma.

The degeneration of joint cartilage and the development of osteoarthritis typically occur over time due to various factors, including mechanical stress and inflammation.

Choice D rationale:

While the exact cause of osteoarthritis is not fully understood, it is not accurate to say that it is entirely unknown.

Osteoarthritis is believed to result from a combination of factors, including genetics, aging, joint injury, and mechanical stress.

Understanding these risk factors can help in its prevention and management.

Choice A rationale:

"Maintaining a healthy weight." Maintaining a healthy weight is an essential preventive strategy for osteoarthritis.

Excess weight can put added stress on joints, increasing the risk of osteoarthritis and worsening symptoms.

Choice B rationale:

"Avoiding all forms of physical activity." This statement is not appropriate because physical activity, when done correctly, can actually help prevent osteoarthritis or manage its symptoms.

Avoiding all physical activity is not a recommended strategy.

Choice C rationale:

"Engaging in regular physical activity." This is the correct choice.

Regular physical activity, such as low-impact exercises and strength training, can help prevent osteoarthritis and improve joint health.

It also helps in managing the condition if already present.

Choice D rationale:

"Smoking regularly." Smoking is not a preventive strategy for osteoarthritis, and it can have numerous adverse health effects.

It is not recommended as a part of osteoarthritis prevention.

Choice E rationale:

"Practicing joint protection techniques." This is another correct choice.

Joint protection techniques, such as using assistive devices, maintaining proper posture, and avoiding excessive joint stress, are essential for preventing further joint damage in individuals with osteoarthritis.
