B is wrong because water contamination does not directly relate to respiratory health.

A postmenopausal female client diagnosed with osteoporosis asks the nurse how a decrease in estrogen can cause problems with bon
larisa [96]

Answer:

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.
