Psychobiologic Disorders Questions
Question 1 of 5
In which location of the cardiovascular system is the highest concentration of baroreceptors?
Correct Answer: C
Rationale: The correct answer is C: The aorta and carotid arteries. Baroreceptors are sensors that detect changes in blood pressure. The highest concentration of baroreceptors is found in the aorta and carotid arteries because these are major arteries close to the heart and brain, which are crucial for maintaining blood pressure regulation. The aorta and carotid arteries constantly monitor blood pressure and send signals to the brain to help regulate it. Choices A, B, and D are incorrect because the carotid veins, supraclavicular arteries, and femoral arteries do not contain as high a concentration of baroreceptors as the aorta and carotid arteries, which play a significant role in blood pressure regulation.
Question 2 of 5
The nurse is caring for a client with schizophrenia. Orders from the physician include 100 mg chlorpromazine IM STAT and then 50 mg PO bid; 2 mg benztropine PO bid prn. Why is chlorpromazine ordered?
Correct Answer: C
Rationale: Correct Answer: C - To decrease psychotic symptoms Rationale: 1. Chlorpromazine is a typical antipsychotic used to manage psychotic symptoms in schizophrenia. 2. It acts by blocking dopamine receptors in the brain, helping to alleviate hallucinations and delusions. 3. The IM STAT dose provides rapid relief, followed by the oral dose for maintenance. 4. Benztropine is an anticholinergic used to manage extrapyramidal symptoms, not chlorpromazine. 5. Chlorpromazine does not prevent neuroleptic malignant syndrome or induce sleep. Summary: A: Incorrect - Chlorpromazine does not primarily reduce extrapyramidal symptoms. B: Incorrect - Chlorpromazine does not prevent neuroleptic malignant syndrome. D: Incorrect - Chlorpromazine is not primarily used to induce sleep.
Question 3 of 5
The nurse is interviewing a client on the psychiatric unit. The client tilts his head to the side, stops talking in midsentence, and listens intently. The nurse recognizes from these signs that the client is likely experiencing:
Correct Answer: C
Rationale: The correct answer is C: Auditory hallucinations. When a client tilts their head to the side, stops talking, and listens intently, it suggests that they are hearing something that others cannot, indicating auditory hallucinations. This behavior aligns with the sensory experience of hearing voices. Somatic delusions (A) involve false beliefs about one's body, not auditory experiences. Catatonic stupor (B) is characterized by immobility and unresponsiveness, not specific behavioral cues like tilting the head. Pseudoparkinsonism (D) refers to drug-induced symptoms resembling Parkinson's disease, not related to the client's behavior during the interview.
