Question 5 of 5

A 74-year-old woman states that many of her peers underwent hormone replacement therapy (HRT) in years past. The woman asks the nurse why her primary care provider has not yet proposed this treatment for her. What fact should underlie the nurse's response to the woman?

A. The risks of stroke and breast cancer are unacceptably high in women taking HRT. B. HRT was found to cause mood disturbances in many women who used it long term. C. HRT was found to be a significant risk factor for bone fractures and osteoporosis. D. The risks of chronic obstructive pulmonary disease were found to be significantly higher in women using HRT.

Correct Answer: A

Rationale: The correct answer is A because the main reason HRT is not recommended for all women is due to the increased risks of stroke and breast cancer associated with its use. Choices B, C, and D are incorrect as they do not address the primary concerns regarding HRT use. HRT can indeed cause mood disturbances and may have effects on bone health, but the main concerns regarding its use revolve around the risks of stroke and breast cancer.
