The nurse is caring for a client with onychomycosis (nail
fungus) who is receiving oral terbinafine (Lamisil) for treatment. The client
questions the need for 3 months’ worth of pills. What is the nurse’s best
response?

1. “The health care provider will evaluate the nails monthly
and stop treatment earlier if warranted.” 2. “It is cheaper to buy more pills
at one time than on a monthly schedule.” 3. “The extensive prescription avoids
the need for shorter term, potentially toxic doses.” 4. “Nails grow slowly and
the nail beds must receive adequate length of treatment to eliminate the
infection.”
