CNS Pharmacology Drug Quiz Questions
Question 1 of 5
A 63-year-old man with a history of Parkinson's disease and generalized anxiety is placed on a first-generation antipsychotic medication. Characteristics of this class of medications include which of the following?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Adverse effect of morphine include all of the following EXCEPT:
Correct Answer: D
Rationale: Morphine's adverse effects stem from mu receptor agonism. Physical and psychological dependence (choice A) arises from chronic use, activating reward pathways. Constipation (choice B) results from reduced GIT motility, a common issue requiring laxatives. Respiratory depression (choice C), the most dangerous, depresses brainstem respiratory centers, critical in overdose. Hyperpyrexia (choice D), or fever, is not a morphine effect; opioids typically cause hypothermia in overdose due to CNS depression, unlike stimulants. This exception highlights morphine's depressant profile, essential for monitoring and distinguishing it from other drug classes causing hyperthermia.
Question 3 of 5
Aspirin is useful in treatment of:
Correct Answer: B
Rationale: Aspirin treats simple headaches (choice B) via COX inhibition, reducing prostaglandin-mediated pain. Bronchial asthma (choice A) may worsen with aspirin due to leukotriene shifts. Peptic ulcer (choice C) is contraindicated due to GI irritation. Viral infections in children (choice D) risk Reye's syndrome with aspirin. Headache relief is a standard use, reflecting its analgesic efficacy.
Question 4 of 5
Acetylsalicylic acid (aspirin) produces all of the following actions EXCEPT:
Correct Answer: C
Rationale: Aspirin provides analgesic/antipyretic (choice A), anti-inflammatory/anti-rheumatic (choice B), and anti-platelet effects (choice D) via COX inhibition. Uricosuric action (choice C) occurs at high doses (>4g/day), not small doses, where it retains uric acid, potentially worsening gout. This exception clarifies dose-dependent effects, critical for therapeutic precision.
Question 5 of 5
The following are true about neurolept analgesia EXCEPT:
Correct Answer: B
Rationale: Neurolept analgesia, from droperidol (antipsychotic) and fentanyl (opioid) (choice A), provides analgesia (choice D) and antiemetic effects (choice C) without full unconsciousness, unlike general anesthesia. Loss of consciousness (choice B) isn't typical; patients remain responsive. This exception defines its use in procedures needing sedation and pain control.
