The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?

A. Consult with a pharmacist about scheduling the dose one hour after the client eats: Risedronate should be taken first thing in the morning, at least 30 minutes before any food or drink other than water, to maximize absorption. B. Withhold the medication until the client's breakfast tray is available on the unit: Giving risedronate with breakfast will significantly reduce absorption, making the medication less effective. The priority is to administer it with plain water on an empty stomach. C. Assign an unlicensed assistive personnel (UAP) to bring the client a glass of low fat milk: Milk contains calcium, which binds to risedronate and prevents its absorption. This would make the dose ineffective and should be avoided during administration. D. Instruct the client that it is necessary to take nothing but water with the medication: Risedronate should be taken with a full glass of plain water only, followed by remaining upright for at least 30 minutes, to prevent esophageal irritation and ensure optimal absorption.
