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 D rationale
When assessing a patient with an altered level of consciousness, the nurse’s initial action should be to assess the patient’s response to pain. This is a fundamental part of the neurological examination and can provide valuable information about the patient’s level of consciousness and neurological function. Pain response can be assessed by applying a painful stimulus, such as a pinch, and observing the patient’s reaction.
Choice A rationale
Assessing the patient’s ability to follow complex commands is an important part of the neurological examination, but it is not typically the initial action when assessing a patient with an altered level of consciousness. This assessment requires a higher level of cognitive function and may not be possible in a patient with significantly altered consciousness.
Choice B rationale
Assessing the patient’s judgment is an important part of the mental status examination, but it is not typically the initial action when assessing a patient with an altered level of consciousness. Like the ability to follow complex commands, judgment requires a higher level of cognitive function and may not be assessable in a patient with significantly altered consciousness.

Choice C rationale
Assessing the patient’s verbal response is an important part of the neurological examination, but it is not typically the initial action when assessing a patient with an altered level of consciousness. The patient’s ability to speak and the content of their speech can provide important information about their neurological function, but this assessment may not be possible in a patient with significantly altered consciousness.

Choice C rationale
Dimming the lights and reducing stimulation can be an effective nursing intervention for a patient with herpes simplex virus encephalitis who is complaining of a headache. Bright lights and excessive noise can exacerbate headaches, so creating a quiet, dimly lit environment can help to alleviate this symptom.
Choice A rationale

While administering hydromorphone as needed can help to manage the patient’s pain, it does not directly address the patient’s complaint of a headache. Moreover, opioids like hydromorphone can have side effects such as drowsiness and constipation, which may not be desirable in a patient with encephalitis.
Choice B rationale
Distracting the patient with activity may not be appropriate for a patient with herpes simplex virus encephalitis who is complaining of a headache. Rest and quiet are often more beneficial for these patients.
Choice D rationale
Initiating a patient-controlled analgesia (PCA) of morphine sulfate can provide effective pain relief for some patients, but it may not be the best first-line approach for a patient with a headache due to herpes simplex virus encephalitis. Like hydromorphone, morphine can have side effects such as drowsiness and constipation.
