A nurse is caring for a client who has osteoporosis and a new prescription for raloxifene. Which of the following should the nurse assess prior to initiating therapy?

A. "CBC results": While it is important to monitor blood counts during treatment for various conditions, CBC results are not specifically required before initiating therapy with raloxifene. Raloxifene is not known to have a direct impact on blood cell production. B. "Family history of colon cancer": While a family history of colon cancer is important for overall health assessments, it is not directly related to the initiation of raloxifene therapy. Raloxifene is used primarily for bone health and does not require an assessment of colon cancer history. C. "Thyroid function": Thyroid function is not directly related to the initiation of raloxifene. Raloxifene primarily affects estrogen receptors and bone metabolism, and thyroid function is not a routine screening requirement for this medication. D. "Pregnancy status": Raloxifene is contraindicated in pregnancy because it can cause harm to the fetus. It is essential to confirm that the client is not pregnant before initiating therapy, as this medication is classified as a pregnancy category X drug.
