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?
Non-Hodgkin's lymphoma.
Endometriosis.
Breast cancer.
Polycystic ovary syndrome.
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A rationale:
The nurse should plan to administer Ampicillin to the client with a group B streptococcus (GBS) B-hemolytic infection. Ampicillin is the first-line antibiotic treatment for intrapartum prophylaxis in GBS-positive pregnant women. It helps prevent the transmission of the bacteria from the mother to the newborn, reducing the risk of early-onset GBS infection in the infant.
Choice B rationale:
Azithromycin is not the appropriate choice for treating GBS B-hemolytic infection during labor. While Azithromycin is effective against certain bacteria, it is not the recommended antibiotic for GBS prophylaxis in labor. Ampicillin or Penicillin is the preferred medication in this scenario.
Choice C rationale:
Ceftriaxone is not the appropriate medication for treating GBS B-hemolytic infection during labor. Ceftriaxone belongs to the cephalosporin class of antibiotics and is not the first-line treatment for GBS prophylaxis. Ampicillin or Penicillin is the preferred choice.
Choice D rationale:
Acyclovir is an antiviral medication and is not indicated for the treatment of GBS B-hemolytic infection. GBS is a bacterial infection, and antiviral medications like Acyclovir do not have an effect on bacteria.
Correct Answer is C
Explanation
Choice A rationale:
Vitamin E is essential for cell function and acts as an antioxidant. While vitamin E is important during pregnancy, there is no specific recommendation to increase its intake during gestation. The recommended daily allowance (RDA) for vitamin E during pregnancy is 15 mg.
Choice B rationale:
Vitamin D is crucial for calcium absorption and bone health. However, it is not explicitly advised to increase vitamin D intake during pregnancy, and it largely depends on the individual's baseline vitamin D levels. The RDA for vitamin D during pregnancy is 600 IU.
Choice C rationale:
Fiber is essential during pregnancy as it helps prevent constipation, which is a common problem due to the increased levels of progesterone. A high-fiber diet also helps in maintaining healthy blood sugar levels, which is important to avoid gestational diabetes.
Choice D rationale:
Calcium is vital for the development of the baby's bones and teeth. While it is an important nutrient during pregnancy, the body's ability to absorb calcium improves during pregnancy, so the recommended intake does not increase as much as fiber.
