CNS Stimulants Drugs Pharmacology Quiz Questions
Question 1 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 2 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.
Question 3 of 5
The following drugs are useful in management of gout EXCEPT:
Correct Answer: A
Rationale: Colchicine (choice B) treats acute gout by reducing inflammation, Allopurinol (choice C) lowers uric acid long-term, and Sulphinpyrazone (choice D) promotes urate excretion. Thiazide diuretics (choice A) increase uric acid retention, worsening gout, making them the exception. This distinguishes gout management from contraindicated drugs.
Question 4 of 5
Drugs useful to initiate sleep include which of the following:
Correct Answer: D
Rationale: Flurazepam (choice A), Triazolam (choice B), and Chlordiazepoxide (choice C), all benzodiazepines, initiate sleep via GABAa potentiation, differing in duration (long, short, intermediate). ‘All of the above' (choice D) is correct, as each is a hypnotic, tailored to insomnia needs, highlighting benzodiazepine versatility.
Question 5 of 5
Side effects of MAO inhibitors include the following EXCEPT:
Correct Answer: B
