What nursing diagnosis is suggested by a client who states they take extra griseofulvin when their infection worsens?

The nursing diagnosis of deficient knowledge related to correct medication use is appropriate for a client who mistakenly takes extra griseofulvin when their infection worsens. This behavior indicates that the client may not fully understand the appropriate dosing or the rationale behind their medication regimen.

Griseofulvin is an antifungal agent used to treat skin and nail infections, and it is crucial for patients to adhere to the prescribed dosage to avoid potential side effects or reduced effectiveness of the treatment. Taking more than the recommended dose could lead to unnecessary complications or excessive drug accumulation, reinforcing the notion that the client lacks the necessary knowledge about how to properly manage their medication.

This highlights the importance of patient education in pharmacological treatments, ensuring that clients are aware of the correct usage and implications of their medications. By addressing this knowledge gap, nurses can support better health outcomes and medication adherence for the client.
