ANS:  A

In AD, the level of ACh in the brain is reduced. ACh is the primary neurochemical that affects memory and the ability to acquire new information. Donepezil is an anticholinesterase inhibitor and improves symptoms by making more ACh available. The drug does not have any of the actions mentioned in the other options.

4. The focus of nursing care for a patient diagnosed with dementia is:

ANS:  C

Because memory is impaired, an individual with dementia cannot learn easily, so maintaining functioning as long as possible is important. The patient’s abilities are expected to decline over time. Use of the word “optimum” suggests the changing nature of the level of functioning. Individualizing care and promoting esteem and confidence are of lesser importance than maintaining optimal function.
