Chapter 25 Cardiovascular Drugs Quizlet Questions
Question 1 of 5
A client diagnosed with bipolar I disorder is exhibiting severe manic behaviors. A physician prescribes lithium carbonate (Eskalith) and olanzapine (Zyprexa). The client’s spouse asks the nurse how Zyprexa works. Which is the appropriate nursing response?
Correct Answer: D
Rationale: The correct answer is D: “Zyprexa calms hyperactivity until the Eskalith takes effect.” Rationale: 1. Zyprexa (olanzapine) is an atypical antipsychotic used to treat manic symptoms in bipolar disorder by stabilizing mood. 2. Lithium carbonate (Eskalith) is a mood stabilizer that takes time to reach therapeutic levels and effectiveness. 3. Zyprexa acts quickly to calm hyperactivity and aggression associated with mania while Eskalith gradually takes effect to stabilize mood long-term. 4. Therefore, the appropriate nursing response is to explain that Zyprexa helps manage acute symptoms until Eskalith fully kicks in. Other Choices: A: Incorrect. Zyprexa does not cure manic symptoms but helps manage them alongside Eskalith. B: Incorrect. Zyprexa does not prevent extrapyramidal side effects, which are more commonly associated with typical antipsychotics. C
Question 2 of 5
A patient with schizophrenia has received typical (first-generation) antipsychotics for a year. His hallucinations are less intrusive, but he remains apathetic, has poverty of thought, cannot work, and is socially isolated. To address these symptoms, the nurse might consult the prescribing health care provider to suggest a change to:
Correct Answer: B
Rationale: The correct answer is B, olanzapine (Zyprexa). Olanzapine is an atypical (second-generation) antipsychotic that is known to target negative symptoms of schizophrenia such as apathy, poverty of thought, and social withdrawal. It is also effective for treating positive symptoms like hallucinations. This medication can help improve the patient's overall functioning and quality of life. Choice A, haloperidol, is a typical antipsychotic similar to what the patient has already been taking, which may not effectively target the negative symptoms. Choice C, diphenhydramine, is an antihistamine and not indicated for schizophrenia. Choice D, chlorpromazine, is also a typical antipsychotic and may not address the negative symptoms effectively. Overall, olanzapine is the best choice for addressing the patient's remaining symptoms.
Question 3 of 5
In New South Wales, Australia, personal cannabis use has been:
Correct Answer: B
Rationale: The correct answer is B: decriminalised. In New South Wales, personal cannabis use is not fully legal but is treated as a minor offense, resulting in a fine or caution rather than criminal charges. Decriminalisation aims to reduce the burden on the criminal justice system while maintaining some level of control over cannabis use. This approach is a middle ground between full legalisation (C) and de facto legalisation (D), where cannabis use is widely accepted without formal legalisation. Criminalisation (A) entails serious legal consequences for cannabis use, which is not the case in New South Wales.
Question 4 of 5
The __________ constitute a class of drugs that are commonly prescribed for cardiac arrhythmias but also have been found to be effective treatment for social phobias.
Correct Answer: D
Rationale: The correct answer is D: Beta-blockers. Beta-blockers are commonly prescribed for cardiac arrhythmias due to their ability to block the effects of adrenaline on the heart. In the context of social phobias, beta-blockers can help reduce physical symptoms of anxiety such as rapid heart rate and trembling, making them an effective treatment option. A: Benzodiazepines are typically used to treat anxiety disorders, but they are not specifically known for treating social phobias. B: Tricyclics are a class of antidepressants and are not commonly prescribed for social phobias. C: Azaspirones are anxiolytic drugs used to treat generalized anxiety disorder and are not commonly used for social phobias.
Question 5 of 5
A patient with a history of depression reports not feeling well rested in recent weeks. Before making the assumption that the complaint is related to depression, a nurse should investigate whether the patient has had any recent changes in:
Correct Answer: A
Rationale: The correct answer is A: work schedule that affect the hours of sleep. This is because changes in work schedule can directly impact the amount and quality of sleep a person gets, leading to feelings of not being well-rested. Investigating this factor is important before assuming the complaint is solely related to depression. Choice B: vacations taken within the same time zone, is incorrect as vacations within the same time zone should not significantly affect sleep patterns unless there are other factors involved. Choice C: fluid intake with reduced overall intake of water, is incorrect because while hydration is important for overall health, it is less likely to be the primary cause of not feeling well-rested. Choice D: food intake with decreased intake of heavy foods before bedtime, is incorrect as while diet can impact sleep quality, it is less likely to be the primary cause of feeling not well-rested in this case.
