A nurse is reviewing a new prescription for alendronate 70 mg PO once per week upon waking to be taken 30 min before food, fluids, or medication with a client who has osteoporosis. The client is to remain upright for 30 min after administration. How should the nurse interpret this prescription for the client?

A. The client can return to bed after taking the medication, but before eating: Alendronate requires the client to remain upright for at least 30 minutes after administration to reduce the risk of esophageal irritation. Returning to bed immediately would increase complications. B. Take the medication at 1800, 30 min after the evening meal: Alendronate must be taken upon waking in the morning, at least 30 minutes before the first food, beverage, or other medication, to optimize absorption. Evening dosing after meals reduces its effectiveness. C. Over-the-counter oral preparations can be taken with this medication: Other oral medications, vitamins, or supplements, especially calcium or antacids interfere with alendronate absorption and should not be taken at the same time. D. Choose the same day of each week to take this medication: Alendronate 70 mg is prescribed once weekly and should be taken consistently on the same day each week to maintain steady therapeutic levels and improve adherence.
