A nurse is caring for a client who has placenta previa. Which of the following interventions should the nurse implement for this client? (Select all that apply.)

Choice A rationale:
Tamoxifen is not used to treat Non-Hodgkin's lymphoma. Tamoxifen is a selective estrogen
receptor modulator (SERM) and is primarily used in breast cancer treatment. It functions by
binding to estrogen receptors, blocking estrogen's effects, and inhibiting the growth of
hormone-sensitive breast cancer cells.
Choice B rationale:
Tamoxifen is not used to treat endometriosis. Endometriosis is a condition in which tissue
similar to the lining of the uterus grows outside the uterus, and it is typically managed with
hormonal therapies, pain medications, or surgical interventions, but not tamoxifen.
Choice C rationale:

This is the correct choice. Tamoxifen is widely used in the treatment of breast cancer,
especially in cases of estrogen receptor-positive breast cancer. It helps prevent cancer
recurrence and is often prescribed for both early-stage and advanced breast cancer patients.
Choice D rationale:
Tamoxifen is not used to treat polycystic ovary syndrome (PCOS). PCOS is a hormonal
disorder characterized by enlarged ovaries with small cysts, and it is typically managed with
lifestyle changes, hormonal contraceptives, and medications to regulate menstrual cycles and
manage symptoms like hirsutism and acne.

Choice A rationale:

Nulliparity (never having given birth) is a known risk factor for ovarian cancer. Women who have never had children have a higher risk compared to those who have. This is believed to be associated with the number of ovulatory cycles a woman experiences throughout her lifetime.

Choice B rationale:

History of breastfeeding does not have a direct link to ovarian cancer risk. In fact, breastfeeding is associated with a reduced risk of both breast and ovarian cancer due to hormonal changes that occur during lactation.

Choice C rationale:

Previous use of oral contraceptives is associated with a decreased risk of ovarian cancer. Women who have used birth control pills have a lower risk compared to those who have never used them. The protective effect is believed to be due to the suppression of ovulation.

Choice D rationale:

History of breast cancer is not a risk factor for ovarian cancer. Although both cancers are related to the reproductive system, they have distinct risk factors and characteristics.

Choice E rationale:

Hormone replacement therapy (HRT) is a potential risk factor for ovarian cancer, especially long-term use. The hormones used in HRT can affect hormone levels and may increase the risk of ovarian cancer.
