Which statement by a client taking amlodipine indicates a need for further teaching?

The statement indicating the need for further teaching is the client's assertion that it is important to take amlodipine on an empty stomach. Amlodipine, a calcium channel blocker, can be taken with or without food, as its absorption is not significantly impacted by food intake. Ensuring that clients understand the flexibility in dosing with regard to meals is crucial for adherence to the medication and for managing their condition effectively.

The other statements made by the client demonstrate understanding of the medication's use and precautions. Indicating that they can take amlodipine whenever experiencing pain suggests a misunderstanding of the chronic use of the medication, as it is used for preventing angina rather than treating acute episodes. However, it does show that they are aware of its purpose. The information about not using amlodipine with other calcium channel blockers indicates awareness of potential drug interactions and the need for caution with multiple medications in the same class. Lastly, experiencing fewer angina episodes is a positive response to treatment, showing that the medication is effective for this client.
