Question 5 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.
