Final answer:
The nurse should emphasize taking alendronate on an empty stomach.
Step-by-step explanation:
The correct answer is A: "Be sure to take this medication on an empty stomach."
Alendronate is a medication used to treat osteoporosis. It should be taken on an empty stomach, at least 30 minutes before the first food, drink, or medication of the day. Taking it with food, milk, calcium, or juice can interfere with the absorption of the medication, reducing its effectiveness.
Therefore, it's important for the nurse to emphasize to the client that they should take alendronate on an empty stomach to ensure optimal absorption and effectiveness of the medication.
