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 A rationale:

The nurse should discontinue the oxytocin infusion if the client's contraction frequency is every 3 minutes. Frequent contractions may lead to uterine hyperstimulation, which can reduce fetal blood flow and oxygenation, potentially causing fetal distress. Normal contraction frequency during labor is typically every 2 to 5 minutes.

Choice B rationale:

Contraction duration of 100 seconds is not an indication to discontinue the oxytocin infusion. The duration of contractions can vary during labor, and 100 seconds is within the normal range of contraction duration, which is usually 45 to 90 seconds.

Choice C rationale:

Fetal heart rate with moderate variability is not an indication to discontinue the oxytocin infusion. Moderate variability in fetal heart rate is a reassuring sign, indicating a healthy fetal response to labor. It shows that the fetus is tolerating the contractions well and is not experiencing fetal distress.

Choice D rationale:

A fetal heart rate of 118/min is not an indication to discontinue the oxytocin infusion. The normal fetal heart rate range is typically between 110 to 160 beats per minute, and a heart rate of 118/min falls within this normal range. However, if the fetal heart rate deviates significantly from the normal range or shows signs of distress, further assessment and intervention are required.
