A patient will begin taking a cholinesterase inhibitor for early Alzheimer's disease. The nurse is teaching the patient's spouse about the medication. Which statement by the spouse indicates a need for further teaching?
a. "Gastrointestinal symptoms are common with this medication."
b. "People taking this drug should not take antihistamines."
c. "This drug helps neurons that aren't al-ready damaged to function better."
d. "This drug significantly slows the pro-gression of the disease."
D
Cholinesterase inhibitors produce modest improvements in cognition, behavior, and function and may slightly delay disease progression; they do not have a major impact on delaying progression of the disease. Gastrointestinal symptoms are common side effects. Drugs that block cholinergic receptors, including antihistamines, can reduce therapeutic effects and should be avoided. Cho-linesterase inhibitors do not affect neurons already damaged, but they do improve function in those not yet affected.
