A patient is prescribed alendronate (Fosamax). Which statement indicates that the patient understands teaching about this drug?

Choice A reason: Lying down after taking alendronate increases the risk of esophageal irritation and ulceration. Patients should remain upright for at least 30 minutes post-dose. Choice B reason: Taking alendronate with a full glass of water helps ensure the tablet reaches the stomach quickly and reduces the risk of esophageal damage. This is a critical safety instruction. Choice C reason: Alendronate should be taken on an empty stomach, at least 30 minutes before the first food, beverage, or medication of the day to maximize absorption. Choice D reason: Calcium can interfere with the absorption of alendronate. These medications should be spaced apart to avoid reduced efficacy.
