CNS Stimulants Drugs Pharmacology Quiz Questions
Question 1 of 5
A 71-year-old man with gradual impairment in short-term memory and speech is thought to have Alzheimer's disease. His primary care physician begins him on rivastigmine. This agent will most likely cause which of the following effects?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A 49-year-old man with long-standing schizophrenia is hospitalized for a symptom exacerbation. His primary care physician places him on a second-generation antipsychotic agent. Characteristics of this agent include which of the following?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A 49-year-old man with manic depression has been maintained on lithium for long-term therapy. However, because of worsening of symptoms, he is placed on ziprasidone. The patient must be warned about which of the following adverse effects?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Symptoms of acute morphine toxicity include:
Correct Answer: A
Rationale: Acute morphine toxicity, an overdose scenario, presents a classic triad: coma, pinpoint pupils (miosis), and depressed respiration (choice A). Coma results from profound CNS depression, miosis from parasympathetic overstimulation, and respiratory depression from medullary suppression, often fatal without intervention (e.g., naloxone). Abdominal cramps and diarrhea (choice B) suggest withdrawal, not toxicity. Hypertension and arrhythmias (choice C) align with stimulants, not opioids. Dry mouth and mydriasis (choice D) are anticholinergic signs, opposite to morphine's effects. This triad is critical for rapid diagnosis and treatment in emergency settings, distinguishing opioid toxicity from other syndromes.
Question 5 of 5
The following are useful in management of an acute attack of gout EXCEPT:
Correct Answer: A
Rationale: Acute gout attacks require rapid inflammation reduction. Colchicine (choice B) disrupts microtubule function, reducing neutrophil activity. Indomethacin (choice C), an NSAID, inhibits COX, lowering prostaglandin levels. Glucocorticoids (choice D) suppress inflammation broadly. Allopurinol (choice A), a xanthine oxidase inhibitor, lowers uric acid long-term but doesn't address acute inflammation, making it the exception. This distinction guides acute versus chronic gout management.
