Correct Answer: A

Correct Answer: C

Rationale: The patient is presenting with sudden-onset weakness and sensory loss on one side of the body along with difficulty speaking and understanding speech, which are classic symptoms of a stroke. The involvement of the right middle cerebral artery territory on imaging suggests an acute infarction, confirming an ischemic stroke. Ischemic stroke occurs due to a blockage or obstruction within a blood vessel supplying blood to the brain, leading to a lack of oxygen and nutrients reaching brain tissue. This results in neurological deficits corresponding to the affected area of the brain. In contrast, a transient ischemic attack (TIA) would present with similar symptoms but resolve within 24 hours without evidence of acute infarction on imaging. Intracerebral hemorrhage and subarachnoid hemorrhage involve bleeding into the brain tissue or the space surrounding the brain, respectively, resulting in different clinical presentations.

Correct Answer: A

Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.

Correct Answer: B

Rationale: The most appropriate response from the nurse when a patient expresses frustration with the treatment plan proposed by the healthcare team is to empathize with the patient's frustration and explore their concerns further. It is important to actively listen to the patient, acknowledge their feelings, and address any questions or uncertainties they may have about the treatment plan. By engaging in open communication and demonstrating empathy, the nurse can foster a therapeutic relationship with the patient and work towards finding a solution that is mutually agreeable and beneficial for the patient's well-being. Dismissing the patient's concerns (Option A) or ignoring their frustration (Option C) can lead to a breakdown in communication and trust, which may ultimately impact the patient's compliance with the treatment plan. Similarly, telling the patient that they have no choice but to follow the treatment plan (Option D) can be perceived as dismissive and confrontational, which is not conducive to promoting patient-centered care.

Correct Answer: B

Rationale: The nurse's best approach to address a patient's concerns about the potential side effects of a prescribed medication is to provide the patient with accurate information about potential side effects and management strategies. It is important for the nurse to acknowledge the patient's concerns, listen attentively, and offer clear explanations to help alleviate any fears or uncertainties. Providing accurate information can empower the patient to make informed decisions about their healthcare and feel more confident in taking the prescribed medication. Dismissing or ignoring the patient's concerns can lead to mistrust and non-adherence to the treatment plan. It is essential for the nurse to prioritize open communication and patient education to ensure the patient's well-being and compliance with the prescribed medication regimen.
