A nurse is providing a class on osteoporosis at the local seniors' center. Which statement related to osteoporosis is most accurate?
Excess growth of bone formation causes the bones to weaken
Men are less likely than women to have secondary causes of osteoporosis
A modifiable risk factor for osteoporosis is a person's level of activity
Osteoporosis is categorized as a disease for the elderly
None of the above
The Correct Answer is C
Choice A reason: Excess growth of bone formation does not cause the bones to weaken, but rather the opposite. Osteoporosis is a condition that causes the bones to lose density and become brittle due to the imbalance between bone resorption and formation. The bone resorption exceeds the bone formation, leading to low bone mass and increased fracture risk.
Choice B reason: Men are not less likely than women to have secondary causes of osteoporosis, but rather more likely. Secondary osteoporosis is a type of osteoporosis that is caused by other diseases or medications that affect the bone metabolism. Men are more likely to have secondary osteoporosis due to conditions such as hypogonadism, hyperparathyroidism, hyperthyroidism, or chronic kidney disease, or medications such as glucocorticoids, anticonvulsants, or anticoagulants.
Choice C reason: A modifiable risk factor for osteoporosis is a person's level of activity, as it affects the bone health and strength. Physical activity, especially weight-bearing and resistance exercises, can stimulate the bone formation and prevent the bone loss. It can also improve the muscle strength, balance, and coordination, which can reduce the risk of falls and fractures.
Choice D reason: Osteoporosis is not categorized as a disease for the elderly, but rather a disease that can affect people of any age. Osteoporosis is more common in older adults, especially postmenopausal women, due to the hormonal changes and the natural decline of bone mass with aging. However, osteoporosis can also occur in younger people due to genetic factors, lifestyle factors, or secondary causes.
Choice E reason: None of the above is not a correct choice, as there is one option that matches the most accurate statement related to osteoporosis.

Correct Answer is E
Explanation
Choice A reason: Including an average daily intake of 300 mg of calcium is not a sufficient measure to prevent osteoporosis, as it is below the recommended dietary allowance (RDA) for calcium, which is 1000 mg for adults aged 19-50 years, and 1200 mg for adults aged 51 years and older. Calcium is an essential mineral for bone health, as it helps to build and maintain the bone density and strength.
Choice B reason: Walking 20-30 minutes three days a week is not an optimal measure to prevent osteoporosis, as it is below the recommended physical activity guidelines, which suggest at least 150 minutes of moderate-intensity aerobic exercise per week, and at least two sessions of muscle-strengthening activities per week. Physical activity is beneficial for bone health, as it stimulates the bone formation and reduces the bone loss.
Choice C reason: Engaging in isometric exercise 20-30 minutes weekly is not an effective measure to prevent osteoporosis, as it is not the best type of exercise for bone health, and it is not performed frequently enough. Isometric exercise is a form of exercise that involves contracting the muscles without moving the joints, such as holding a plank or a wall sit. Isometric exercise does not provide enough mechanical stress or load to the bones, which is needed to stimulate the bone remodeling and growth.
Choice D reason: Including adequate intake of vitamin E is not a relevant measure to prevent osteoporosis, as it is not a major nutrient for bone health, and it has no direct effect on the bone metabolism. Vitamin E is an antioxidant that helps to protect the cells from oxidative stress and inflammation, which may have some indirect benefits for the bone health, but it is not a key factor. Vitamin E is also not a common deficiency, and it can be obtained from various foods, such as vegetable oils, nuts, seeds, and green leafy vegetables.
Correct Answer is B
Explanation
Choice A reason: Green vegetables, whole wheat pasta, and poultry are not the best foods to include in the teaching plan when educating a client on increased calcium intake, as they are not rich sources of calcium. Green vegetables, such as kale, spinach, or broccoli, contain some calcium, but they also have oxalates, which can reduce the calcium absorption. Whole wheat pasta and poultry have very little calcium, and they are more sources of carbohydrates and protein, respectively.
Choice B reason: Low-fat milk, salmon with bones, and yogurt are the best foods to include in the teaching plan when educating a client on increased calcium intake, as they are high sources of calcium. Low-fat milk has about 300 mg of calcium per cup, salmon with bones has about 200 mg of calcium per 3 ounces, and yogurt has about 450 mg of calcium per cup. These foods also provide other nutrients, such as protein, vitamin D, and omega-3 fatty acids, which are beneficial for bone health.
Choice C reason: Fish, eggs, and potatoes are not the best foods to include in the teaching plan when educating a client on increased calcium intake, as they are not rich sources of calcium. Fish, such as tuna, cod, or halibut, have some calcium, but only if they are eaten with bones, which is not common. Eggs have about 25 mg of calcium per egg, which is very low. Potatoes have about 20 mg of calcium per medium potato, which is also very low.
Choice D reason: Poultry, broccoli, and yellow vegetables are not the best foods to include in the teaching plan when educating a client on increased calcium intake, as they are not rich sources of calcium. Poultry, such as chicken, turkey, or duck, have very little calcium, and they are more sources of protein and iron. Broccoli has about 40 mg of calcium per cup, which is low. Yellow vegetables, such as carrots, squash, or corn, have very little or no calcium, and they are more sources of vitamin A and fiber.
Choice E reason: Cheese, almonds, and tofu are not the best foods to include in the teaching plan when educating a client on increased calcium intake, as they are not suitable for everyone. Cheese has about 200 mg of calcium per ounce, but it is also high in fat, sodium, and calories, which may not be good for clients with high blood pressure, high cholesterol, or obesity. Almonds have about 75 mg of calcium per ounce, but they are also high in calories, and they may cause allergic reactions in some people. Tofu has about 250 mg of calcium per half cup, but it is also high in phytoestrogens, which may interfere with hormone levels in some people.
