Answer to Question 1

ANS: A
The patient's age and DVT history place her at risk for thrombosis. Tamoxifen would not be indicated for this patient. A prior hysterectomy, osteoporosis, and hyperlipidemia are not contraindications to tamoxifen.

Answer to Question 2

ANS: B
The nurse should withhold the dose if the patient has new-onset cough and dyspnea, because these may indicate the development of interstitial pulmonary changes and acute respiratory distress syndrome. Alopecia would not cause the nurse to withhold the dose. Neutropenia is expected and is not at a critical level. Although this count is low, it would not prevent administration of the medication. Peripheral neuropathy is expected with vinorelbine.
