A nurse is teaching a client who is to start using a diaphragm for contraception. Which of the following client statements indicates an understanding of the teaching?

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 C rationale:

Hypotension is a finding that indicates the client is experiencing decreased cardiac output. Excessive vaginal bleeding can lead to hypovolemia, reducing the volume of blood pumped by the heart and resulting in decreased cardiac output. The body responds to hypovolemia and decreased cardiac output by trying to maintain blood pressure, which leads to hypotension.

Choice A rationale:

Bradycardia is not a finding indicating decreased cardiac output in this scenario. While bradycardia (abnormally slow heart rate) can be associated with decreased cardiac output in certain situations, it is not the primary finding in a postpartum client experiencing excessive vaginal bleeding.

Choice B rationale:

A flushed face is not an indicator of decreased cardiac output. A flushed face may result from various factors such as fever or emotional stress, but it is not directly related to cardiac output.

Choice D rationale:

Polyuria (excessive urination) is not an indicator of decreased cardiac output. Polyuria may occur due to factors like diuresis or increased fluid intake but is not directly related to cardiac output in the context of excessive vaginal bleeding.
