The nurse is providing patient education to a patient with early-stage Alzheimer’s disease (AD) and their family. The patient has been prescribed donepezil hydrochloride.
What should the nurse explain to the patient and family about this drug?

Choice B rationale
Patients who experience severe cluster headaches should be instructed to take medications as soon as they sense the onset of symptoms. Cluster headaches are characterized by severe, debilitating pain that reaches peak intensity within a short period of time, often within 15 minutes. Therefore, early intervention is crucial to manage the pain effectively.
Choice A rationale

Waiting twenty to thirty minutes after the onset of symptoms to take medications may not be effective for cluster headaches. The pain of a cluster headache often reaches peak intensity within 15 minutes, so delaying medication could result in unnecessary suffering.
Choice C rationale
Waiting until the patient’s pain becomes unbearable is not recommended for managing cluster headaches. The goal of treatment is to prevent or reduce pain, not to wait until it becomes unbearable.
Choice D rationale
Taking medications when the patient senses their symptoms are peaking is not the most effective strategy for managing cluster headaches. Given the rapid onset and severe pain associated with cluster headaches, medications should be taken as soon as the patient senses the onset of symptoms.

Choice A rationale
Slowing of activity, also known as bradykinesia, is a common symptom of Parkinson’s disease. It is characterized by a general reduction in the speed and amplitude of voluntary movements, leading to difficulties with tasks such as walking, talking, and performing other self-care activities.
Choice B rationale
Muscle flaccidity is not typically associated with Parkinson’s disease. Instead, people with Parkinson’s often experience muscle rigidity or stiffness.
Choice C rationale
A gait with the body leaning backward is not a typical symptom of Parkinson’s disease. People with Parkinson’s disease often have a stooped posture, with the body leaning forward.
Choice D rationale
Continuous tremors are a hallmark symptom of Parkinson’s disease, but they are not present in all cases. Tremors in Parkinson’s disease are often described as a “pill-rolling” tremor because the movement resembles the motion of trying to roll a pill between the thumb and index finger.
