Apostmenopausal female client diagnosed with osteoporosis asks the nurse how a decrease in estrogen can cause problems with bone density. which statement is the best response from the nurse?
a. "a decrease in estrogen levels, which occurs at menopause, results in increased resorption of bone."
b. "estrogen is needed to push calcium into the bone."
c. "a lack of estrogen reduces the number and function of the osteoclasts."
d. "menopause causes a decrease in all circulating hormones, such as pth which lead to a decrease in bone strength."

The correct answer is option a.

Explanation:

Osteoporosis refers to a condition that weakens the bone, and enhances the threat of unanticipated and sudden fractures, also known as porous bones. It leads to an enhanced loss of bone mass and strength. The disease often advances without any kind of pain or signs.  

There is a direct association between the reduction of estrogen post menopause and the emergence of osteoporosis. Postmenopause, the breakdown or resorption of bone takes over the formation of novel bone. Estrogen diminishes the function and number of osteoclasts. Thus, the reduction in the levels of estrogen after menopause leads to bone loss.
