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.

The correct answer is choice C: "I will tip the nipple so air is present as my baby sucks.”
Choice A rationale:

The parent's statement in choice A, "I will keep my baby's head elevated while he is feeding,” indicates an understanding of proper bottle feeding techniques. Keeping the baby's head slightly elevated can help prevent choking and aspiration during feedings. This is a correct statement, and no further instruction is needed in this regard.

Choice B rationale:

The parent's statement in choice B, "I will allow my baby to burp several times during each feeding,” also demonstrates knowledge of appropriate bottle feeding practices. Burping the baby during and after feedings helps release swallowed air, reducing the likelihood of excessive gas and discomfort. This statement is correct, and no additional instruction is required.

Choice C rationale:

Choice C is the incorrect statement because tipping the nipple to introduce air while the baby sucks is not a recommended practice. In fact, it can lead to an increased intake of air, potentially causing gas, discomfort, and colic in the baby. Therefore, further instruction is needed to correct this misconception.

Choice D Rationale:

Choice D is not directly related to the need for further instruction in bottle feeding techniques and is not addressed in the explanation.
