A nurse is teaching the parents of a newborn how to care for their child's uncircumcised penis. Which of the following instructions should the nurse include?

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.

Assess the fetal heart rate pattern.

Choice B rationale:

When a laboring client's membranes have just ruptured, the nurse's next action should be to assess the fetal heart rate pattern. Rupture of membranes can lead to changes in amniotic fluid, which can affect the fetal environment and potentially cause fetal distress. By assessing the fetal heart rate pattern, the nurse can determine if the baby is tolerating the labor process well or if there are signs of fetal compromise that require further intervention.

Choice A rationale:

While assessing the client's blood pressure (Choice A) is important during labor, it is not the immediate next action when the membranes have ruptured.

Choice C rationale:

Taking the client's temperature (Choice C) is also important, but it is not the priority action when the membranes have ruptured.

Choice D rationale:

Preparing for a c-section (Choice D) is not the initial action unless there are specific indications for an emergency cesarean section. Assessing the fetal heart rate is more critical at this stage.
