A nurse is providing teaching to a client who has prostate cancer and a new prescription for leuprolide. The nurse should explain to the client that leuprolide treats prostate cancer by which of the following actions?

A. "Leuprolide decreases the production of testosterone.": Leuprolide is a gonadotropin-releasing hormone (GnRH) agonist that works by reducing testosterone production, which is essential for the growth of prostate cancer cells. This mechanism slows the progression of the cancer. B. "Leuprolide kills cells at all stages of cellular division.": This describes how chemotherapy drugs work, but leuprolide does not function by directly killing cancer cells at different stages of their division. C. "Leuprolide increases estrogen levels in your body to counteract the cancer cells.": Leuprolide does not increase estrogen levels. Instead, it reduces testosterone levels, which is more effective in managing prostate cancer. D. "Leuprolide suppresses the pituitary gland's production of growth hormone to decrease cancer cellular growth.": Leuprolide suppresses the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), not growth hormone, to decrease testosterone levels.
