Write numerical answer only - no units.
The Correct Answer is ["675"]

Correct Answer is B
Explanation
Choice A rationale
Chemotherapy and radiation can significantly affect fertility. It would be incorrect to reassure the patient that these treatments will not impact her ability to become pregnant, as these treatments often reduce fertility or cause temporary or permanent infertility.
Choice B rationale
Discussing fertility counseling and contraception options allows the patient to make informed decisions about her reproductive health. Fertility preservation methods, such as egg or embryo freezing, can be considered before starting treatment. This approach respects the patient's desire to become pregnant while acknowledging the impact of cancer treatment.
Choice C rationale
Referring the patient to a social worker for pregnancy surrogacy is premature and not directly addressing the patient's immediate concerns about fertility and treatment. Fertility counseling is a more appropriate initial step.
Choice D rationale
Delaying treatment for cancer to allow for pregnancy can have severe negative impacts on the patient's prognosis and is not advised. Immediate treatment is crucial to control the disease and improve survival chances.
Correct Answer is C
Explanation
Choice A rationale
Administering isotonic intravenous fluids and a loop diuretic is a treatment for conditions like hypercalcemia or fluid overload but is not appropriate for a patient with metastatic prostate cancer presenting with neurologic symptoms.
Choice B rationale
Administering anticoagulants and supplemental oxygen is a treatment for pulmonary embolism but does not address the neurologic symptoms and back pain related to metastatic prostate cancer.
Choice C rationale
Frequent neurologic assessments and administering intravenous corticosteroids are essential for managing spinal cord compression, a common complication in metastatic prostate cancer that can cause back pain, weakness, and paresthesia.
Choice D rationale
Interferon beta-1a is used in multiple sclerosis to reduce inflammation and immune response. Stretching exercises may help but are not the primary intervention for acute neurologic symptoms in metastatic prostate cancer. .
