Correct Answer is D
Explanation
Obesity is a primary risk factor for the development of osteoarthritis, particularly in weight-bearing joints such as the knees and hips. Excess weight puts increased stress on the joints, leading to cartilage breakdown and the development of osteoarthritis. While age, family history, and a sedentary lifestyle can also contribute to the development of osteoarthritis, obesity is the most significant risk factor.
a. While age over 65 years is a risk factor for osteoarthritis, it is not the primary risk factor. Osteoarthritis can occur at any age, especially if other risk factors are present.
b. Family history of osteoporosis is not a primary risk factor for osteoarthritis. Osteoarthritis and osteoporosis are separate conditions with different risk factors.
c. While a sedentary lifestyle can contribute to the development of osteoarthritis, it is not the primary risk factor. Obesity is a more significant risk factor in this context.
Correct Answer is A
Explanation
Instructing the client to take frequent breaks during activities to rest the affected joints helps reduce stress and prevent worsening of symptoms. Avoiding the use of assistive devices can lead to increased joint strain and pain, so it is essential to encourage their appropriate use. Performing high-impact exercises is not recommended, as they can worsen joint pain and damage. Applying a heating pad for an extended period is not advisable, as it can cause burns and skin irritation.
b. "Avoid using assistive devices to prevent dependency on them." Encouraging the appropriate use of assistive devices is important for clients with osteoarthritis to reduce joint stress during daily activities.
c. "Perform high-impact exercises regularly to strengthen your joints." High-impact exercises can exacerbate joint pain and damage in clients with osteoarthritis. Low-impact exercises are recommended instead.
d. "Apply a heating pad for at least 1 hour to alleviate joint pain." Applying a heating pad for an extended period can cause burns and skin irritation. Using a heating pad for short intervals is appropriate for pain relief.
