Question 1

Cells that break down or remove bone and get the bone ready for remodeling are known as _____.&#10;A) osteotes&#10;B) osteospurs&#10;C) osteoblasts&#10;D) osteoclasts

Accepted Answer

Osteoclasts are the cells responsible for breaking down bone tissue, a process known as bone resorption, which is essential for bone remodeling and calcium homeostasis.

Question 2

What are the most common sites of fractures related to osteoporosis?&#10;A) hip, wrist, and vertebrae&#10;B) wrist, hand, and foot&#10;C) hip, knee, and vertebrae&#10;D) hand, knee, and foot

Accepted Answer

The most common sites of fractures related to osteoporosis are the hip, wrist, and vertebrae due to their susceptibility to weakening and fractures as bone density decreases.

Question 3

Which group is at the highest risk for osteoporosis?&#10;A) African American women age 50 or older&#10;B) African American women between the ages of 20 and 40&#10;C) white women age 50 or older&#10;D) white men age 50 or older

Accepted Answer

White women age 50 or older are at the highest risk for osteoporosis due to lower bone density and hormonal changes after menopause.

Question 4

The World Health Organization defines osteoporosis as a bone mineral density value _____ the mean reference value for young women&#10;A) equal to&#10;B) more than 2.5 standard deviations below&#10;C) more than 2.5 standard deviations below&#10;D) more than 2.5 standard deviations above or below

Accepted Answer

Osteoporosis is defined by the World Health Organization as having a bone mineral density that is more than 2.5 standard deviations below the mean reference value for young women.

Question 5

Which two nutrients are of greatest importance for patients with osteoporosis?&#10;A) vitamin D and iron&#10;B) vitamin A and calcium&#10;C) vitamin D and calcium&#10;D) calcium and iron

Accepted Answer

Vitamin D and calcium are crucial for bone health, as calcium is a primary component of bone, and vitamin D helps the body absorb calcium effectively.

Question 6

Which osteoporosis treatment is administered once a year via IV therapy?&#10;A) zoledronic acid&#10;B) denosumab&#10;C) risedronate&#10;D) calcitonin

Accepted Answer

Zoledronic acid is administered once a year via intravenous (IV) therapy for the treatment of osteoporosis.

Question 7

Which type of medication has been implicated in bone loss?&#10;A) beta blockers&#10;B) stimulants&#10;C) anticoagulants&#10;D) anticonvulsants

Accepted Answer

Anticonvulsants have been associated with bone loss due to their effect on vitamin D metabolism, which can lead to decreased bone density.

Question 8

The prevalence of osteoporosis is expected to increase significantly as the population ages.

Accepted Answer

As the population ages, the number of individuals at risk for osteoporosis increases, leading to a higher prevalence of the condition.

Question 9

In general, BMD testing should be performed on all women aged 65 and older regardless of risk factors.

Accepted Answer

BMD (Bone Mineral Density) testing is recommended for all women aged 65 and older as a standard practice to assess the risk of osteoporosis and fractures, regardless of other risk factors.

Question 10

Physical activity in adulthood modestly increases bone mass and reduces bone loss.

Accepted Answer

Physical activity stimulates bone formation and slows down bone loss, contributing to increased bone density and strength.
