A patient started Alendronate (Fosamax) once a week for the treatment of osteoporosis. The nurse determines that further instruction about the drug is needed when what is said by the patient?

Choice A reason: Alendronate must be taken on an empty stomach with a full glass of water to ensure proper absorption and minimize esophageal irritation. Taking it with a meal reduces its bioavailability, as food interferes with absorption in the gastrointestinal tract. This statement indicates a misunderstanding, requiring further instruction. Choice B reason: Sitting or standing upright for at least 30 minutes after taking Alendronate is correct, as it prevents esophageal reflux and irritation, a common side effect. This position allows the drug to pass into the stomach, reducing the risk of esophagitis, making this statement accurate and not requiring correction. Choice C reason: Alendronate works by inhibiting osteoclast activity, preventing bone resorption, and promoting bone density increase. This statement is correct, as the drug’s mechanism supports bone health in osteoporosis patients. It reflects an accurate understanding of the drug’s purpose, so no further instruction is needed here. Choice D reason: Continuing calcium supplements with Alendronate is correct, as osteoporosis treatment requires adequate calcium and vitamin D to support bone formation. Alendronate enhances bone density, but calcium is essential for its efficacy, making this statement accurate and not requiring additional teaching.
