A nurse is reviewing a client's medical record and notes that the client is taking tamoxifen.
The nurse should identify that tamoxifen is used to treat which of the following conditions?

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:

Digoxin is a cardiac glycoside and is primarily used in the management of certain heart conditions, such as heart failure and atrial fibrillation. It is not indicated for hyperemesis gravidarum, which is severe and persistent vomiting during pregnancy.

Choice B rationale:

Calcium gluconate is a mineral supplement used to treat calcium deficiencies. It is not a standard treatment for hyperemesis gravidarum.

Choice C rationale:

Vitamin Bs (B6 and B12) are commonly used to manage hyperemesis gravidarum. Vitamin B6, also known as pyridoxine, has been shown to alleviate nausea and vomiting during pregnancy. Vitamin B12 may also be administered to help manage symptoms. Both vitamins are safe to use during pregnancy.

Choice D rationale:

Propranolol is a beta-blocker used to treat high blood pressure, heart conditions, and migraines. It is not recommended for managing hyperemesis gravidarum and is generally avoided during pregnancy due to potential risks to the developing fetus.
