A patient with mild symptoms of Alzheimer Disease is prescribed donepezil, Which statement made by the patient indicates the need for further teaching?

Choice A rationale: Patient-controlled analgesia (PCA) devices provide a controlled dose of medication when the patient presses the button. However, the onset of action for morphine is typically faster than 10 minutes.
Choice B rationale: PCA devices often have a lock-out period to prevent patients from administering too many doses too quickly and risking overdose.
Choice C rationale: Patient-controlled analgesia is designed for the patient to self- administer the medication. Allowing family members to press the button may lead to inaccurate dosing.
Choice D rationale: Morphine should be administered as needed, not preemptively.
Administering the medication 10 minutes before physical therapy could result in excessive sedation.

Choice A rationale: Donepezil works by enhancing the action of acetylcholine, improving neuronal transmission, so this statement is accurate.
Choice B rationale: Upset stomach is a common side effect of donepezil, and the patient's awareness of this potential side effect indicates understanding.
Choice C rationale: Taking donepezil with food can reduce the risk of stomach upset, so this statement is appropriate.
Choice D rationale: Donepezil helps manage symptoms of Alzheimer's Disease but does not stop the progression or damage to neurons. Further education is needed on the realistic expectations of the medication.
