A client develops a seizure disorder as a result of a traumatic fall. During a clinic visit, the client states, "I have not had a seizure in 2 years. When can I stop taking my antiseizure medications?" Which response would the nurse provide? "A gradual reduction in seizure medication may be considered." "You will require medication for the rest of your life." "The medication probably will be discontinued at this visit." "A minimum of 10 years without seizures is necessary before discontinuation of medications is considered."

"A gradual reduction in seizure medication may be considered." (Specific protocols are designed to gradually reduce the dosage of antiseizure medications after a client is seizure free, provided the electroencephalogram is within acceptable limits. The client is monitored for seizure activity because recurrence is greatest within the first year after medication withdrawal.)

The nurse provides teaching regarding vitamin B12 injections to a client with pernicious anemia. Which statement by the client indicates that teaching was understood? "I must take this medication for the rest of my life." "I should take this vitamin, as needed, when feeling fatigued." "Once my symptoms subside, I can stop taking this vitamin." "I need to have this available for use during exacerbations of anemia."

Because the intrinsic factor does not return to gastric secretions even with therapy, B12 injections will be required for the remainder of the client's life.
