A nurse is discussing recommendations for daily nutrient intake during pregnancy with a client who is at 10 weeks of gestation. For which of the following nutrients should the nurse instruct the client to increase intake during pregnancy?

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:

The client's statement about needing to have the IUD replaced each year is incorrect. The lifespan of most IUDs is longer than a year. Copper IUDs can last up to 10 years, and hormonal IUDs can last between 3 to 7 years, depending on the brand.

Choice B rationale:

The client's statement about needing to apply a spermicide prior to intercourse is unrelated to the correct use of an intrauterine device (IUD) for contraception. Spermicides are not required when using an IUD.

Choice C rationale:

The client's statement about expecting periods to stop while having the IUD is incorrect. Hormonal IUDs can often lead to lighter periods, and in some cases, periods may stop altogether. However, with a copper IUD, periods usually remain the same.

Choice D rationale:

This is the correct choice. The client's statement indicates an understanding of the teaching. Checking for the string each month after menstruation is crucial because it confirms that the IUD is still in place, reducing the risk of unintended pregnancy.
