C. Impaired health maintenance might be applicable if the client was not adhering to prescribed drug therapy, but this diagnosis doesn't address the need for education.

D. Self-care deficit may apply if the client is unable to perform necessary self-care activities due to physical limitations but does not address the educational aspect of dietary changes.
