A caregiver of a client diagnosed with AD asks the nurse about the cholinesterase inhibitor galantamine prescribed for the client. Which response by the nurse would be most appropriate?
- A. The drug will help to cure the memory problems the client is experiencing.
- B. Once the symptoms improve, the drug will most likely be stopped.
- C. These drugs help to slow the progression of the disease.
- D. This drug is primarily given to control the delirium the client is experiencing.
Correct Answer: C
Rationale: The progression of memory loss associated with dementia is treated with cholinesterase inhibitors. These drugs slow progression but do not cure dementia. These drugs are given to clients with mild to moderate dementia, but they do not treat any delirium that the clients may experience. Cholinesterase inhibitors are not frequently used in late-stage AD.
