Use of Psychotropic Medications Questions
Question 1 of 5
While the nurse is taking the history of a 68-year-old patient who sustained a head injury 3 days earlier, he tells the nurse that he is on a cruise ship and is 30 years old. The nurse knows that this finding is indicative of a(n):
Correct Answer: D
Rationale: The correct answer is D: Decreased level of consciousness. The patient's confusion about his age and location after a head injury indicates disorientation, a classic sign of altered mental status. This is likely due to the head injury affecting his brain function, leading to impaired cognitive abilities. This finding raises concern for decreased level of consciousness, as the patient is unable to accurately perceive his age or location. Summary: A: Great sense of humor - This choice is incorrect as the patient's response is not a deliberate attempt at humor. B: Uncooperative behavior - This choice is incorrect as the patient's response is not indicative of intentional noncompliance. C: Inability to understand questions - This choice is incorrect as the patient's response suggests more than just a simple misunderstanding of questions.
Question 2 of 5
A 69-year-old patient has been admitted to an adult psychiatric unit because his wife thinks he is getting more and more confused. He laughs when he is found to be forgetful, saying 'I'm just getting old!' After the nurse completes a thorough neurologic assessment, which findings would be indicative of Alzheimer disease? Select all that apply.
Correct Answer: C
Rationale: The correct answer is C. Misplacing items, such as putting dish soap in the refrigerator, is indicative of Alzheimer's disease as it reflects difficulties with executive functioning and memory. This behavior goes beyond occasional forgetfulness (choice A) and having trouble finding the right word (choice D). Difficulty performing familiar tasks (choice B) can also be a sign of Alzheimer's, but misplacing items is more specific to memory and executive function impairment. In this case, the patient's behavior suggests a pattern of cognitive decline rather than just normal aging.
Question 3 of 5
A patient has delusions and hallucinations. Before beginning treatment with a psychotropic medication, the health care provider wants to rule out the presence of a brain tumor. For which test will a nurse need to prepare the patient?
Correct Answer: B
Rationale: The correct answer is B: Computed tomography (CT) scan or magnetic resonance imaging (MRI). To rule out a brain tumor, a CT scan or MRI is essential because they provide detailed images of the brain structure, allowing healthcare providers to visualize any abnormalities such as tumors. Step-by-step rationale: 1. CT scan and MRI are common imaging tests used to detect structural abnormalities in the brain, including tumors. 2. These tests provide detailed cross-sectional images of the brain, enabling healthcare providers to assess the presence of any masses or lesions. 3. By evaluating the images from a CT scan or MRI, healthcare providers can determine if a brain tumor is present before initiating treatment with psychotropic medication. Summary of other choices: - A: Cerebral arteriogram is used to visualize blood vessels in the brain and is not specifically for detecting brain tumors. - C: PET or SPECT scans are more useful in assessing brain function and blood flow, rather than detecting structural abnormalities like tumors.
Question 4 of 5
A patient has anxiety, increased heart rate, and fear. The nurse would suspect the presence of a high concentration of which neurotransmitter?
Correct Answer: D
Rationale: The correct answer is D: Norepinephrine. In anxiety and fear, the body's "fight or flight" response is activated, leading to increased heart rate and heightened arousal. Norepinephrine is a neurotransmitter that plays a key role in this response by increasing heart rate, blood pressure, and alertness. A high concentration of norepinephrine is associated with these symptoms. A: GABA is an inhibitory neurotransmitter that typically has a calming effect, so a high concentration of GABA would not produce symptoms of anxiety and increased heart rate. B: Histamine is involved in allergic reactions and regulates sleep-wake cycles, not typically associated with anxiety and increased heart rate. C: Acetylcholine is involved in muscle control and memory, not directly related to anxiety symptoms such as increased heart rate and fear. In summary, the presence of anxiety, increased heart rate, and fear points towards a high concentration of norepinephrine due to
Question 5 of 5
A nurse cares for patients taking various medications, including buspirone (BuSpar), haloperidol (Haldol), trazodone (Desyrel), and phenelzine (Nardil). The nurse will order a special diet for the patient taking:
Correct Answer: D
Rationale: The correct answer is D: phenelzine (Nardil). Phenelzine is a monoamine oxidase inhibitor (MAOI) that requires a special diet low in tyramine to prevent hypertensive crisis. Tyramine-rich foods like aged cheese, cured meats, and fermented foods can interact with MAOIs. Buspirone, haloperidol, and trazodone do not have specific dietary restrictions related to their mechanisms of action.
