Question

which of the following is a therapeutic action of raloxifene?

blocks the effects of estrogen on endometrial tissue

mimics the effects of estrogen on bone tissue

stimulates secretion of parathyroid hormone

stimulates menstruation

Explanation:

Raloxifene is a selective estrogen receptor modulator (SERM). It acts as an estrogen agonist on bone tissue, meaning it mimics estrogen's effects there to help prevent osteoporosis. It is an antagonist on endometrial tissue (so it doesn't block estrogen effects there in a way that's a therapeutic action for its main use), it doesn't stimulate parathyroid hormone secretion (in fact, it helps with bone health by reducing bone resorption, opposite of PTH's role in some ways), and it doesn't stimulate menstruation. So the correct option is the one about mimicking estrogen effects on bone tissue.

Answer:

B. Mimics the effects of estrogen on bone tissue (assuming the options are labeled A, B, C, D with A being "Blocks the effects of estrogen on endometrial tissue", B "Mimics the effects of estrogen on bone tissue", C "Stimulates secretion of parathyroid hormone", D "Stimulates menstruation")
