Exophthalmos (choice A) is hyperthyroid, renal failure (choice B) and hemolysis (choice C) aren't typical risks. Cardiac caution is key.

Question 5 of 5
Progesterone is added to estrogens in hormone replacement therapy (HRT) to achieve which ALL of the following effects EXCEPT:
Correct Answer: A
Rationale: In HRT, progesterone counters unopposed estrogen effects, reducing endometrial cancer risk (choice D) by opposing endometrial proliferation, and may allow lower estrogen doses (choice B) while aiding bone loss prevention indirectly (choice C). It doesn't increase estrogen's breast action (choice A); it may mitigate breast proliferation, a cancer risk factor. This exception reflects progesterone's protective role in HRT, primarily safeguarding the endometrium, not enhancing breast effects, which aligns with minimizing risks like breast cancer in postmenopausal women.
